In particular, if you've really given yourself a good chance to see something - i.e., with no moon in the sky, and with a number of different eyepiece combinations in your instrument of choise - then a negative observation is just as interesting as a success! It's up to you whether to put "(NOT SEEN)" in your Subject line for these logs: I always do, but some others choose not to. Clear skies!

According to one of the forwards below, it has been seen in a 3.5" scope - presumably from a dark site, but still... ! :) This gorgeous, loose, well-known SAB galaxy may be considered tricky to find, due to a lack of bright landmark stars in Cam. It definitely requires decent charts and some starhopping, and the nearest starting points are either mag 3.5 Omicron UMa (aka "Muscida") some 8 degrees to the SE, or the pretty orange star Pi UMa, mag 4.5, which lies about about 7 degrees to the E. Once the hop is over, though, NGC2403 is well worth it - with or without the excitement of a mag 11 supernova inside, it is a very pretty sight in even moderate scopes, from a dark site: http://www.visualdeepsky.org/logs/msg01014.html http://www.visualdeepsky.org/logs/msg02044.html http://www.visualdeepsky.org/logs/msg03028.html PS: Here are emails from various sources, with supplementary details on this extraordinary extragalactic event!

This suggests the progenitor is a massive star, so thus a less-luminous type II supernova rather than type I (white dwarf progenitor).

If you don't live too far from northwestern Pennsylvania (USA), your attendance at Astroblast could mean a great deal to members of the Oil City Astronomical Society as you'll soon see. Below is a letter from Tim Spuck, President of ORAS. It's hard to believe the grief this small club has been going through lately. In fact, as you'll read, they had to get an injunction just to hold Astroblast this year. If you can possibly attend, please do so. They are a great group of guys and a large crowd would certainly tell the Parks Unlimited company where to get off. Astroblast is held August 17 - 22, with the 2 big days being Friday and Saturday, 8/20, 21. Details are available at: http://www.oras.org. Click the Astroblast link in the larger window. Thanks for your help. Terry ***************************************************** ORAS Members and Friends: As many of you are aware, Park Management has been attempting to stop Astroblast 2004. This has been a very challenging time for us, but this morning we won our first battle. The courts will be granting our request for an injunction that will prevent Park Management from interfering with Astroblast 2004. As a result Astroblast 2004 will be held as planned and as scheduled. (I'll let you know when the official paperwork is signed.) Thanks for all your support, and we are looking forward to seeing you at Astroblast 2004, August 17 - 22!! Tim If you want some background on what has been going on, these were my comments to the Park Board in reference to the issue. It will give you a better idea of what has taken place and ORAS's position. Prepared by: Tim Spuck, ORAS President Date: July 20, 2004, VPNRA Meeting I?ve prepared a written statement as I was unsure we would be provided an opportunity to speak at this meeting. Since July 9th I?ve personally visited the Galaxy Federal Credit Union twice, and called twice requesting to speak with your Chairperson Linda Lusher. Each time I left messages asking that she please contact me to verify that we were on today?s agenda. I?ve yet to be contacted. Last August at the close of the meeting between Ann Rudegeair, George Thompson, Mike Hadley, and myself I would never have guessed I would be here again. When people look at you and shake your hand it?s supposed to mean something; it?s how I was brought up. Unfortunately, to some people it has come to mean very little. On February 16, 1993 the group now known as the Oil Region Astronomical Society entered into an agreement with the County of Venango. In part that agreement would bring an Observatory to Two Mile Run County Park. The Oil Region Astronomical Society would at its own cost construct and operate the facility, and the County would insure and maintain the facility, as well as maintain the grounds at Lockwood and provide unobstructed access to the facility. Shortly after the Rudegair?s began managing the park the County?s obligations in this agreement were not being met. Among other issues the grounds were not being maintained and snow removal in the winter stopped. We understood the financial pressure the County was experiencing and wanted to try and do our part to help out. However coming to a mutual agreement with Park Management seemed all but impossible. Things finally came to head and ORAS was forced to seek legal council. Last summer Ann Rudegeair (Parks Unlimited), George Thompson (County?s legal council), Mike Hadley (ORAS?s legal council), and myself (ORAS President) had a fairly intense negotiation to see if differences could be resolved. By the end of the session an amicable resolution was achieved. This resolution would be realized in the form of a modified lease agreement. Both sides had come to agreement on the issues that would be included in the new agreement. Included in that agreement was language pertaining to Astroblast - ?Astroblast participants would not have to secure camping permits and they would have free access to the showers at Two Mile Run Park Campgrounds near the Lake.? A survey of the grounds would be completed and the document signed prior to the end of the year. Astroblast 2003 was able to move forward in September based on our efforts. We began planning Astroblast 2004 in the Fall shortly after the end of Astroblast 2003. Speakers were secured and advertisements went out to major magazines early in 2004. I had stopped by George Thompson?s office a couple times to check on the progress of the modified lease agreement and was reassured that everything was OK and that things were on track. The County once again was going through its own hardship dealing with the loss of $1.4 million, and we believed this was causing delays in finishing the draft of the new document. Unfortunately that was not the case. Imagine my surprise when we received a letter from Jim Greenfield (Park Authority?s legal council) requesting $1000 from ORAS in order to move the new agreement forward. My first reaction was, ?OK ... this is a mistake. I recall the $1000 being discussed, but it was not to come from ORAS it was to be paid to Park?s Unlimited by the County.? Following a couple more emails, I decided to visit the County Commissioner?s office in an attempt to resolve the matter. While there I spoke with Denise Jones. Ms. Jones recalled discussions last year with Bob Murray and others about the County paying the $1000. She said she would bring it up to the current Commissioners. The $1000 was an amount being demanded by Parks Unlimited from ORAS to move the process forward. The County rightly recognized that it had obligations to ORAS in the lease that Parks Unlimited (thus the County) was not fulfilling for some time. The $1000 was an agreed upon settlement in hopes to move the process forward. On June 9th the County approved the release of $1000, and a check was sent to the Park Authority/Parks Unlimited. ORAS hoped this would now move the process forward. However Parks Unlimited had other plans. On June 8th Ann and Marty came to the Observatory around 12:00 PM. I was at the site working on our new outdoor classroom and remote telescope project. The conversation started politely enough, but ending with Ann yelling, ?I may not be able to stop expansion of your facility, but I can stop Astroblast. You will not be holding Astroblast this year!? Shaking her finger at me again Ann stated, ?No ... Astroblast will not take place!? Marty started shaking his finger at me too, yelling something in the background, but I couldn?t hear him clearly over the idle of the tractor I was on. Why would anyone want to try and stop a project that holds such benefit for the people of Venango County? It doesn?t stop their either. On June 10th Ann Rudegeair sent a slanderous email to County Commissioners in regards to ORAS and the payment of the $1000. The County (both previous and current Commissioners) rightly recognized that it had obligations to ORAS in the lease that Parks Unlimited (thus the County) was not fulfilling. The $1000 was an agreed upon settlement in hopes to move the process forward. In the email Ann states that, ?ORAS stole public funds and that it was no different than what Gary Rhodes had done.? (Mr. Rhodes is accused of embezzling $1.4 million from the County.) I stop and think about all the hours and monetary contributions so many of us have given to Venango County and the entire region through the Observatory and the Oil Region Astronomical Society. To have your representative make such a comment goes far beyond being unprofessional and enters into the realm of what is unconscionable. Unfortunately, the writing was pretty much on the wall at that point. The Observatory is such a rare treat in our struggling community. I think of growing up and wishing I had a place like this to visit. Why anyone would not want to see it succeed is beyond me. But on June 28th Mike Hadley received a letter from Jim Greenfield stating that a substantial portion of the land designated for ORAS in the modified lease, as agreed to by Ann Rudegeair and George Thompson in August 2003, had already been leased to a local farmer for cultivation on April 30, 2003. This means Ann Rudegeair sat in the meeting in August and agreed to something she had no intention whatsoever of doing. Either she knew it and did it anyway, and that would make it dishonest. Or she did not recall and that would be an act of incompetence. Either way the time, the money ORAS had spent, and what we had agreed to in that session was now officially out the window. Add to this the fact that ORAS?s lease dated February 16, 1993 contains language that would prohibit such an agreement with the local farmer from being valid. The icing on the cake comes on July 8th when the $1000 is returned with the explanation being the Park Authority/Parks Unlimited had written it off as a bad debt and therefore had no place to deposit the funds. We obviously have many issues to confront at this point. Many of which can not be addressed at this meeting. The outdoor classroom project is well under way at the Observatory. These plans were shared with the County and Parks Unlimited in April 2003, they were discussed and additional requested documentation was provided. At the time of our meeting in August 2003, construction was to take place that Fall. All permits were secured. The only reason it did not take place was because of poor weather. It was part of the old lease as well as the new agreement. I stated clearly in the meeting what our intentions were, and nobody said ?No?. Why, as Ann stated, would she have wanted to prevent it from happening? I have many questions and too few answers relative to what has happened this past year. We have been planning ASTROBLAST 2004 for nearly a year. We planned it based on the shaking of hands. That used to mean something; what does it mean to the members of the Venango Park and Natural Resources Authority Board? If you believe there is honor in such a gesture then you would agree today that ASTROBLAST 2004 should take place as planned. You would not, as some among you have stated, attempt to stop the event which is the Observatory?s life-line. You would agree, today, the event nor the participants of ASTROBLAST 2004 will be assessed fees, and attendees will be provided access to showers. All I?m asking is that you keep the word of your representative. The event is right around the corner and June was just too late to expect changes. In closing I have a couple requests. First, don?t tell me how much you value and think the Observatory is an asset to this community. I?ve heard that before and frankly it?s too late. Words have come to mean very little. If you believe the Observatory is an asset, then it will become apparent in the action that you take. Secondly, I want to extend an invitation to each of you to attend ASTROBLAST in August. If you can?t spend the whole weekend then come for a day, if you can?t spend a whole day then come for an hour. Come see what it is, before you attempt to destroy it. Thank you for your time.

Brighter one ("central part") is gradually brighter toward its own center, while fainter, situated to the east or NE of central nebula part, is uniform and brighter toward dark streak by central part. Longer observing and averted vision gives better view, showing second part much more extended and fading out very slowly in the darkness toward NE. It also helps to see another, the faintest part of M 8, situated southern of the central part, separated also by a dark stripe. It is large, uniform, and slowly fades out. NGC 6530 is a bright open cluster involved in this nebula, situated eastern of nebula center. It is perfectly round and contains about 20-25 stars of similar brightness.

Situated very close to its rival M 12, a rather similar globular cluster. Not completely resolved at 40x, because of notable central condensation, but at 100x it was almost completely resolved, with five notably brighter stars than other. It was perfectly round, unlike its neighbour, with much brighter core gradually fading out. There were many stars scattered in its field of view, few of them somewhat brighter.

Averted vision helps in observing this cluster just to see how it fades out relatively slowly. Central brightening is weak, but obviuos. There is a bright star near the cluster.

Density of dimmer stars is the same as outside this grouping. I'm not sure if this is the cluster at all, because Cr 367 is supposed to be 30' to the S (acording to map). This means that this group of stars barely overlaps with the position of the cluster on the map (around 1 degree E of M8). I believe my map is wrong because this grouping really looks like typical Collinder cluster (no dimm stars, just scattered group of bright stars). All togehter, it's nothing worth starhopping to.

The cluster appeared to almost touch the neighboring star and I estimated it's diameter to be 3'. This is the first time that some globular looks bigger to me than it really is. Usually, my estimated diameters are between 1/3 and 1/5 of the real diameter! 48x: The cluster shrinks a little, but it's still as big as 2'30"! 79x: With direct vision, I see a uniform moderately bright nebula. Averted vision shows central brightening. I called my friend Igor to help me estimate the diameter of the cluster by comparing its diameter with the distance (1'52") between the cluster center and the neighbouring star. His diameter estimate was 2'40, while mine was 2'. I finally confined this cluster to its real borders :). 140x: The cluster looks even smaller!

Difficult object under less than perfect observing conditions. -- Optional related URLs: ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Tue Aug 17 11:09:51 2004 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 17 Aug 2004 15:09:51 -0000 Subject: (IAAC) Obj: NGC 6804 - Inst: 15 inch Obsession f4,5 Message-ID: <20040817150951.29119.qmail@sedna.atmob.org> ---- Observation Poster: Armin Hermann Observer: Armin Hermann Your skills: Advanced (many years) Date/time of observation: 16 Aug 2004 Location of site: Sangkhlaburi, Thailand (Lat 15?N, Elev 200m) Site classification: Exurban Sky darkness: better 5mag Seeing: 9+ <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 15 inch Obsession f4,5 Magnification: 131 and 342x Filter(s): none Object(s): NGC 6804 Category: Planetary nebula.

I myself was particularly interested in NGC 6337 - during my many visits to the nearby Bug Nebula, I don't recall ever observing this bright, decent-sized PN before. :) By the way, for objects like n6543, don't hesitate to put a "common name" in the Object field of your log, along with the NGC or other number. E.g., in this case, if you want, you can submit a log for: Object: NGC 6543 (Cat's Eye Nebula) That way, when other observers search on that common name rather than the NGC number, they will still pull up your fine observing log! Clear skies (hope your monsoon are over for the year?) And keep the great logs coming!

Djorgovski 2 -- This eyepiece seems to be a very good match for this scope. With an exit pupil of 2mm and a reasonably good (but not unmanageable magnification), it really performs well on deepsky objects. Now that I know where to look for this cluster, it's not difficult. In fact, it's probably more obviou now than when I first saw it at the TSP. However, that's probably due to familiarity with it, since the skies here (although not bad) are certainly not Prude Ranch skies...

The haze appears to be slightly oblong and brighter on one edge. -- Optional related URLs: ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Sat Aug 21 12:01:26 2004 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 21 Aug 2004 16:01:26 -0000 Subject: (IAAC) Obj: NGC 6717 (Palomar 9) - Inst: 14.5" f4.5 TeleKit Message-ID: <20040821160126.29066.qmail@sedna.atmob.org> ---- Observation Poster: Len Philpot Observer: Len Philpot Your skills: Intermediate (some years) Date/time of observation: 05/19/2004 08:50 UT Location of site: Prude Ranch (TSP), Ft.

Averted vision and rocking the scope helped to me to detect and see this galaxy. Looking up the size of the galaxy this morning I discovered that there was another galaxy in the same field and thinking back I believe I detect it as well. This needs to be revisited under better seeing conditions. I was surprised that I could detect this galaxy - seeing was degrading and there was some high haze in the air causing a lot of scatter from the moon. -- Optional related URLs: ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Wed Aug 25 10:49:54 2004 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 25 Aug 2004 14:49:54 -0000 Subject: (IAAC) Obj: ngc 7009 - Inst: c14, f/11 Message-ID: <20040825144954.15256.qmail@sedna.atmob.org> ---- Observation Poster: Scott L.

I don't believe it's COMPLETELY subjective - otherwise, the meteor data- gathering methods of the IMO would never work! And recent success in predicting meteor outbursts proves that they do in fact work well. Anyway, that's off-topic for IAAC: but I did want to mention that LM is primarily dependent on clean air, and on lack of light pollution - and NOT necessarily on altitude above sea level! I observe meteors (and deep sky) frequently from spots around the US (and one very wonderful week in China for the 2001 Leonids). And my experience is that skies in the Florida Keys - if one can still manage to escape the ubiquitous European-style resort hotels that are sadly marring the landscape more and more down there - can be just as dark as those at altitudes of 2000m or more in the American Southwest. The only observing site that I can unequivocally say has shown me better Limiting Magnitudes than I often got on the best nights from the Florida Keys in the past decade - would be the 2700m site on Mauna Kea in Hawai'i! (The actual observatories up at 4100m could assuredly give still better skies - but my flatlander, swamp-bottom lungs sadly just could not manage too well up at that height! :->) Now this isn't to say that the skies at SOME sites near sealevel aren't completely overcome by heavier moisture condensation in the air - coupled with light and air pollution... My observing in the Florida Everglades in recent decades makes that sadly clear. All of that said, of course, there is some reasonable debate as to whether EXTENDED faint objects are better perceived at altitude, than they are at sea level: I think there is definitely something to this, particularly near the tropics, where the effects of airglow (the natural emission of night-time atmosphere that has been bathed in sunlight all day) can be very prominent indeed from dark sites. And of course, where you have less air, there's also less airglow! Clear skies all!

One of the best ever. Clark Creek is located on the Pamlico Sound near Stumpy Point with an unobstructed view to the South and East toward the Atlantic Ocean. (75:51:12W; 35:35:53N) The following is pasted directly from the evenings report. ?Fabulous Skies at Clark Creek? 6 Nov. 2002 14:30 EST I arrived at the Clark Creek observing site in time to enjoy a colorful sunset between torrential showers and swarms of mosquitoes. As the rains came down I waited around for Eric Honeycutt. I finally decided that it was a bad evening and I wasn?t about to get out to be carried away by the hoards of flying villains so I drove back to the highway to wait for Eric. Along about 18:30 Eric arrived and he wanted to go on to the observing site and wait out the showers. He had verified that clearing was eminent, so back to the end of the access road named Pamlico Road that ends in the swampy grassland along the north side of the Pamlico Sound Between Stumpy Point and Engelhard south of US264. Sometime between 19:00 and 20:00 the sky mostly cleared and as the rain soaked into the sandy soil we decide to set up the scopes and prepare to stay the course. We laid every thing out on a tarp, but by the time we had both the 12? SCT and the 22? Dob set up the puddles were all gone, but things were still wet. A breezy wind was blowing which helped dry things and kept the mosquito hoards at bay. While there were clouds scudding by, we noticed a weak but broad light dome to the north about where the bombing range is located and another to the west at Engelhard. As the clouds thinned out the light domes all but disappeared and a few scattered clouds were like black ink blots moving across the sky. The sky transparency was phenomenal and seeing not so good toward the north. However to the south and east out across the water the seeing had to be 8/10 or better. The 3rd diffraction ring was visible most of the time in the 12? even if it did quiver a lot. The transparency was great right down to the horizon. About a quarter of a mile to the south of Clark creek is a levee with small scrub pines and the stars of Orion were showing through the limbs of the trees as the constellation rose above the horizon. Absolutely unbelievable transparency. Later as Triangulum was nearly at the zenith, M33 appeared as a fingerprint on the celestial window. It was the first time I have seen it without carefully star hopping to get the correct location and then seeing it as a faint smudge with averted vision. It was as easy to see as M31 is normally. This time it was a real attention getting experience to be remembered forevermore. I don?t believe I ever remember a better sky anywhere and I have seen some beautiful skies in the Carolina and Virginia mountains and the Southwest and in the high plateau in Washington State, but none were remembered to be as good as tonight at Clark Creek and it at sea level. I observed M33 with the 12? and the spiral arms really stood out against the blackness of the sky, black not deep blue. NGC604 was obvious and IC143 was suspect. All this in an f:10; 12?; SCT. It just isn?t possible, but I saw it, no doubt about it. The view was just overwhelming. I revisited NGC206 in M31 to confirm what I recorded at MASP on 02, Nov., 2002, on Figure D34A, I recorded Globular Cluster, G52 near NGC206. It is the first truly extragalactic Glob that I am aware of seeing. I observed it at MASP with the 22?, but I could also see it in the 12? at Clark Creek.

Gramer" Date: 2004/08/26 Thu AM 11:32:54 EDT To: "'IAAC: Internet Amateur Astronomers Catalog of Visual Deep-SkyObservations'" Subject: Re: (IAAC) Obj: M 27 - Inst: 24 cm dobsonian, f/6.6 Limiting Magnitude is indeed a very observer-specific thing. I don't believe it's COMPLETELY subjective - otherwise, the meteor data- gathering methods of the IMO would never work! And recent success in predicting meteor outbursts proves that they do in fact work well. Anyway, that's off-topic for IAAC: but I did want to mention that LM is primarily dependent on clean air, and on lack of light pollution - and NOT necessarily on altitude above sea level! I observe meteors (and deep sky) frequently from spots around the US (and one very wonderful week in China for the 2001 Leonids). And my experience is that skies in the Florida Keys - if one can still manage to escape the ubiquitous European-style resort hotels that are sadly marring the landscape more and more down there - can be just as dark as those at altitudes of 2000m or more in the American Southwest. The only observing site that I can unequivocally say has shown me better Limiting Magnitudes than I often got on the best nights from the Florida Keys in the past decade - would be the 2700m site on Mauna Kea in Hawai'i! (The actual observatories up at 4100m could assuredly give still better skies - but my flatlander, swamp-bottom lungs sadly just could not manage too well up at that height! :->) Now this isn't to say that the skies at SOME sites near sealevel aren't completely overcome by heavier moisture condensation in the air - coupled with light and air pollution... My observing in the Florida Everglades in recent decades makes that sadly clear. All of that said, of course, there is some reasonable debate as to whether EXTENDED faint objects are better perceived at altitude, than they are at sea level: I think there is definitely something to this, particularly near the tropics, where the effects of airglow (the natural emission of night-time atmosphere that has been bathed in sunlight all day) can be very prominent indeed from dark sites. And of course, where you have less air, there's also less airglow! Clear skies all!
