Class: Constellation: Eridanus Data: mag -- size Many Degrees Position: RA 4h:03m DEC +3:00' Description: Supernovae and fierce stellar winds from the Orion Stellar Association have blown large quantities of gas and dust out of the region surrounding the Orion, Horsehead, and other nebulae. Half of the gas headed toward the galactic plane where it slowed down as it collided with the interstellar medium. This is Sh2-276, better known as Barnard?s Loop. However, the other half of the gas was blown out, away from the galactic plain where the interstellar medium is less dense. Thus it did not slow down as much and is located much farther from the Orion Association than Barnard?s Loop is. This half is known as the Eridanus Bubble, and it is cataloged as Sh2-245. A good website that with images of the Eridanus bubble can be found at: http://canopus.physik.uni-potsdam.de/~axm/...bble_Halpha_600. However, how observable is this Eridanus Bubble? I had failed every time I had tried to see this very faint emission region from Alabama. However, on the night of 12/21 I was at last able to bag it. Starting with OIII filtration and 75X, I followed a tip of where to start the search, and may have detected a slight increase in sky background brightness as I swept the scope in an E-W direction at the coordinates 4h 02m +3 30?. Popping in the UHC got me more excited. I definitely was beginning to pick something up! Inserting the H-beta filter sealed the case. Using the H-beta, I was able to follow an EXTREMELY faint strip of nebulosity about 15?-20? wide from 4h 2m +3 45? south-southeast to about 4h 3m +2 10? at which point the nebulosity slowly faded from view. When I got back from Texas, I was able to finally find images of this nebular complex to see that this is just the brightest section of a huge, ~10 degree object. Chalk yet another object up as an H-beta target. -- 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 Fri Aug 3 14:19:16 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 14:19:16 -0400 Subject: (IAAC) Obj: Sh2-282 - Inst: 18" f/4.5 Message-ID: <20070803181916.13967.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/21/06 Location of site: Davis Mountains, 10 miles outside of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 Magnification: 76X Filter(s): UHC, OIII, H-beta Object(s): Sh2-282 Category: Emission nebula.

While Sh2-280 isn?t that bad and I had observed it from Alabama multiple times, Sh2-282 was a different matter. I had failed to find it at least twice from the more light polluted skies of Alabama. Zeroing in on its location, I started the search using the OIII and 75X. Sweeping back and forth across its location revealed nothing using this filter, so I switched to the UHC, and began to notice a slight nebulosity running in a north-south manner. I quickly replaced the UHC with the H-beta, knowing that any object that is invisible in OIII and begins to become visible in UHC is probably an H-beta target. Indeed! With the H-beta in the system, a definite, 35?x15? strip of nebulosity orientated in the N-S direction became visible in a rich Milky Way starfield. Sweeping the scope was not required to see object. -- 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 Fri Aug 3 14:39:59 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 14:39:59 -0400 Subject: (IAAC) Obj: Abell 3 - Inst: 18" f/4.5 Dob Message-ID: <20070803183959.25471.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/16/06 Location of site: 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: 5 <10-1 Seeing Scale (1 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 Dob Magnification: 110X, 230X, 290X Filter(s): OIII Object(s): Abell 3 Category: Planetary nebula.

After matching the Aladin Previewer chart to the Cassiopeia star field, I was able to pick up a very, very faint disk using 110X magnification and OIII filtration. The disk appeared to be situated just W of a close pair of magnitude 13 stars. The stars provided some interference, but increasing magnification to 230X and 290X in an attempt to minimize this interference decreased the visibility of the nebula. I was unable to hold the disk in adverted vision, but it was able to be dependably reacquired. Nebula was best visible at 110X. -- 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 Fri Aug 3 14:47:19 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 14:47:19 -0400 Subject: (IAAC) Obj: Abell 26 - Inst: 18" f/4.5 Dob Message-ID: <20070803184719.29589.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/16/06 Location of site: 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: 5 <10-1 Seeing Scale (1 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 Dob Magnification: 230X Filter(s): OIII Object(s): Abell 26 Category: Planetary nebula.

I had previously recorded this object as ?probable? from the Conecuh National Forest on 11/23/06, but the darker and higher altitude skies of the Davis Mountains proved the advantage I needed. I took a crack at it on 12/16. At low power, I first matched the Aladin previewer finder chart to the Puppis star field. The match was fairly easy due to a wide triangle of three magnitude ~10 stars 5?-10? west of the nebula. Increasing magnification to 230X and adding the OIII filter revealed a very weak disk at the nebula?s position. The object was able to be reacquired fairly easily and even held for a fleeting moment or two in adverted vision before it would pop out of visibility. A relative lack of stars at near the nebula?s location increased the ease with which the nebula was separated from the background sky glow. -- 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 Fri Aug 3 14:31:15 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 14:31:15 -0400 Subject: (IAAC) Obj: Abell 86 - Inst: 18" f/4.5 Dob Message-ID: <20070803183115.20740.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/16/06, 12/17/06, 12/20/06 Location of site: Davis Mountains, 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 Dob Magnification: 110X, 230X Filter(s): OIII Object(s): Abell 86 Category: Planetary nebula. Class: Constellation: Cepheus Data: mag 16.7p size 70" Position: RA 0h:1.5m DEC +70:43' Description: (Probable observation)- this one was so close to a positive observation I tried to confirm my sighting on 12/16, 12/17 and 12/20. This planetary is one of the more difficult Abells. It comes in as magnitude 16.7p and 70? across. After matching the Cepheus star field with the Aladin Previewer finder chart I made, I was able to acquire an extremely faint, perhaps circular glow on the threshold of perception using 110X and 230X and OIII filtration. A flattened quadrilateral of stars just to west aided in identification of the correct field and image scale. Unfortunately, there were a few very faint stars near the nebula?s location that in extreme adverted vision ?clouded? the view too much to know whether I was perceiving the combined glow of a star or two, or the actual nebula. Reverting to semi-adverted vision for better resolution unfortunately made the nebula impossible to acquire, and even when using full adverted vision, the nebula was not able to be reacquired easily. On the third night I tried to observe this object, I went so far as to say I am 99% confident I saw it. After studying the star field at length, I was able to be almost sure the faint glow I was repeatedly spotting near the position was the nebula and not a pairing of two of the nearby 15th and 16th magnitude stars. Even though Abell 86 has decent separation between it and any wide star pairs you might confuse it with in adverted vision, it?s really tough to determine the exact location of faint circular glow you only see popping into adverted vision every 30 seconds against a background of 15th magnitude stars at 230X with OIII filtration in a telescope without tracking. So in the end, I will have to rate this as a highly promising- but negative- observation. I almost surely saw it, but I have been fooled before. -- 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 Fri Aug 3 14:57:16 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 14:57:16 -0400 Subject: (IAAC) Obj: Abell 29 - Inst: 18" f/4.5 dob Message-ID: <20070803185716.2502.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/16/06, 12/21/06 Location of site: 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 dob Magnification: 75X Filter(s): OIII Object(s): Abell 29 Category: Planetary nebula.

Since I have already seen all the easy Abells, this object is of course another exercise in retinal torture. Its magnitude is 14.3p, but don?t let that fool you; its light is spread out over 482?x335?. Checking back in my notes also reveals that I previously attempted this object on 11/23/06 from the Conecuh National Forest, when I recorded it as 75% probable. Unfortunately, the Texas skies just weren?t enough in this case. It?s located in a fairly dense Pyxis star field, with MANY superimposed stars. Making the match with the Aladin previewer chart at 75X, I added the OIII in a hope to finally convince myself I was seeing this big planetary. I was able to detect a very, very faint, broad glow spread out amongst the superimposed stars at the nebula?s position on both nights. I feel 95% confident I was seeing the object, however, the large number of superimposed stars leaves enough doubt to not rate this as a positive observation. -- 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 Fri Aug 3 15:03:56 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 15:03:56 -0400 Subject: (IAAC) Obj: Abell 83 - Inst: 18" f/4.5 Dob Message-ID: <20070803190356.6616.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/20/06 Location of site: 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: 5 <10-1 Seeing Scale (1 best)> Moon presence: None - moon not in sky Instrument: 18" f/4.5 Dob Magnification: 230X Filter(s): OIII Object(s): Abell 83 Category: Planetary nebula.

Its size is 42?x37?, with a magnitude estimate of 17.6p. I attempted this object on 12/20, a night that was VERY windy and cut short to about 3-4 hours due to these winds. After matching the star field to the Aladin Previewer chart at lower power, I popped in the OIII and increased the power to 230X to try to pull the nebula out of the background. In adverted vision, I was able to fleetingly acquire an incredibly faint, small glow just south of a kite-shaped asterism of magnitude ~14 stars. No significant stars were superimposed or interfered with the object. Unfortunately, I was unable to hold or dependably reacquire the nebula. However, this object was very near the threshold of what I would consider ?dependably reacquiring?. If I was 99% confident with my Abell 86 observation, then I am 99.5% confident I was able to spot this object. There is a small chance that a nearby set of two magnitude ~15.5 stars could have masqueraded as the nebula in adverted vision, however, it?s unlikely because they are significantly displaced from the object?s position.

I had first seen it many years ago but I had never seen it- and never tried to see it- in my 4? refractor. I suspected it would be fairly easy, and I was right. On 12/17 I decided to give A21 a go in my 4? Stellar Vue achromat. At 37X with OIII filtration, I found Abell 21 to be a very easy object in the tiny scope, appearing as a crescent-shaped glow. None of the arcs and filaments that are visible in larger apertures (and give it the name ?Medusa Nebula?) were visible, however. -- 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 Fri Aug 3 15:13:41 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 3 Aug 2007 15:13:41 -0400 Subject: (IAAC) Obj: Abell 31 - Inst: 4" f/6.9 achro Message-ID: <20070803191341.11366.qmail@sedna.atmob.org> ---- Observation Poster: John Tatarchuk Observer: John Tatarchuk Your skills: Advanced (many years) Date/time of observation: 12/17/06 Location of site: 10 miles west of Fort Davis, TX (Lat , Elev 6000') Site classification: Rural Sky darkness: 10 <1-10 Scale (10 best)> Seeing: <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 4" f/6.9 achro Magnification: 26X Filter(s): OIII Object(s): Abell 31 Category: Planetary nebula.

I gave A31 a go in the 4? refractor soon after I had observed A21 in the same scope on 12/17. Putting the 27mm Panoptic (26X) w/OIII in the scope, I started starhopping to nebula?s position. Halfway to through the starhop, I noticed a faint, circular glow of the right dimensions at the edge of the FoV. Centering the faint circular glow, I checked Uranometria and confirmed that it was Abell 31. A set of four magnitude ~10 stars make a wide parallelogram perhaps 20?-25? across. The nebula was a fairly obvious circular glow centered around what appeared to be the south most of these four stars.

It?s main claim to difficulty is the magnitude 7 star that is superimposed on the SW edge. An easy catch in my 18? when I first saw it several years ago, but would the refractor be able to handle it? On 12/21, I gave it a try. Once I placed the refractor on the 7th magnitude star, I popped in the 19mm panoptic (37X) and OIII filter to see what I could see. The nebula was easy, and I was able to hold it in adverted vision. It looked as if some of the light from the magnitude 7 star had spilled out and formed a circular puddle to the northeast. -- 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 11 17:36:39 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 11 Aug 2007 17:36:39 -0400 Subject: (IAAC) Obj: NGC 5678 - Inst: 10" f/4.7 Newtonian reflector Message-ID: <20070811213639.19588.qmail@sedna.atmob.org> ---- Observation Poster: Brent Reary Observer: Brent Reary Your skills: Intermediate (some years) Date/time of observation: 08/07/07 03:10 UT Location of site: Rolla, MO USA (Lat 37 57'N, Elev ) Site classification: Rural Sky darkness: 6.5 Seeing: 7 <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 10" f/4.7 Newtonian reflector Magnification: 80x, 133x, 200x, 267x Filter(s): None Object(s): NGC 5678 Category: External galaxy.

Extent of this dark nebula, just as its opacity and the fact that it is easily visible from the deep sky, are surprising characteristics. Also, the size of B133 is very noticeable at 9x, slightly smaller in surface than the first group of 4 stars forming the western end of the triangle. It is, on the other hand, difficult to see contours, badly definite at this magnification.

Class: Constellation: Aql Data: mag size 180' x 10' Position: RA 19:15.6 DEC +00:13 Description: In Aquila, at ~ 4? S-W of Delta Aql. Completely being unaware of what I tried to observe, in terms of appearance, form and opacity, I tried an observation of couple B137-B138. Covering a great area in central portion of Aquila, no object appeared at the beginning. In scanning the zone carefuly, I finally perceived an dark area drawing a crescent shape, a bit like a first quarter moon. In keeping the eyes at the eyepieces, it appeared obvious to me that there was something at this place, but quite difficult to say what formed B137 or B138. For sure, it is a dark cloud with a crescent shape. It is near of a triangle, at the SE end, of stars HD 181420, 27 Aql and HD 181609, of HD 181907 and TYC 5131-253-1 at the E end, and of 23 Aql in N. By doing much research, I can say now that the crescent shape is B138 and B137 is only one small appendix connected to B138, not visible. In spite of an average opacity, the crescent shape is easily visible, although this last is, in fact, one part of a bigger object. B138 is less detached from the deep sky than B133. The portion at the SSE of 23 Aql is particularly obvious. -- Optional related URLs: http://video.library.gatech.edu/Barnard_Project_W/platechart/platechart40.jpg ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Tue Aug 14 13:22:38 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 14 Aug 2007 13:22:38 -0400 Subject: (IAAC) Obj: B143, Barnard "E" cloud - Inst: Vixen 9x63 binoculars Message-ID: <20070814172238.5207.qmail@sedna.atmob.org> ---- Observation Poster: St?phane Meloche Observer: St?phane Meloche Your skills: Advanced (many years) Date/time of observation: 2007/07/22 6h08 UT Location of site: St-Joseph-de-Coleraine (Qc) Canada (Lat 45.96?, Elev ) Site classification: Exurban Sky darkness: 5.8 Seeing: <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: Vixen 9x63 binoculars Magnification: Filter(s): Object(s): B143, Barnard "E" cloud Category: Dark nebula.

At the beginning, I believed that the strong brightness of Alta?r (Alpha Aql) and Tarazed were going to harm the observation, but their proximity of B143 is negligible. The nebula is really dark and draws a ?L? rather than a ?E?, simply because the E is supplemented by B142.

Knew it would be extremely hard or even impossible, but after success in most of the Abell planetaries, UGC galaxies and Palomar globulars I made out just before, which were not visible few nights before I gained lot of self confidence and hope. First I have found exact position of the galaxy at 406x, which was not visible at first glance as of constant looking to the LCD screen, then, after some adaptation switched to 1118x. Already at lower power I saw it would be extremely hard as everything was so smaller and fainter - galaxy center was not visible at all. Switching to that very high power I had still quite clear image, as I checked on the nearby star. So I could definitely resolve some 1 arcsecond between the components. But where are they? After some jerking with averted vision and raping the eye I was able to see galaxy's center as a fuzzy patch of light. Remember, I had only about 2,5' FOW so could definitely see it was not stellar, but quite large - such as those 4-5 arcseconds that the Cross should be. But unfortunately nothing more. It was so faint I could only hold it steadily with averted vision and after half and hour or more got so tired of trying that it disappeared sompletely. Although, at some moments, it seemed to me the core was not round but more like a square even with prominent tops, I can only think it is more likely averted imagination. So, negative report for Einstein's Cross or Q2237+030. I should wait an opportunity for at least few inches larger scope. --------------------------------- Ready for the edge of your seat?

Class: Constellation: TAU Data: mag 16? size Position: RA 4:21.94 DEC +19:31.88 Description: I have tried many times for this in smaller scopes, but never seen anything. In the 30-inch it was just a faint little bright patch on the west side of T Tauri. Not clearly defined but just bright enough that I could pick it out from the surrounding sky. There was just a little dark lane between it and T Tauri, so I could tell it wasn't just glare from the star. A bit fainter but still visible in higher powers, slightly elongated. Jiggling the scope help to bring it out a little better. LPR (Deep Sky) filter helped the contrast a tad. UHC and OIII made it dim and disappear, respectively, as one would expect. The position above is mine. It's a tiny arc about 45 arcseconds W to WSW of T Tauri. -- Optional related URLs: ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html
