Class: V Constellation: Coma Berenices Data: mag 8 size < 5' Position: RA 13h:10.5m DEC +18:c.20 Description: At all points I see a faint smear 1-3?(across) the roundish shape and glow like a very dim lamp. Best found by finding a double-triangle asterism to its direct N and then, on the right side triangle, scanning down a degree or so. I see it very faintly with 10 x 50 Nikon Lookout II binoculars on a night like tonight, moon down five days or so ago. Alpha Comae is a few degrees further S, S.E. Filters UCH and Deep Sky show a tiny bit of definition. Still no outliers but I get a granular view in this tightly compacted ball. Averted vision reveals more of this and some small lanes. You know: a sandy texture. I did NOT see the neighbor NGC 5053, even if at lower power (X25, X40)and with a filter/ without, had the object right in the same ocular, to include the pair a few seconds of arc N. Burnham indicated that this globular has one of the lowest luminosities recorded. This object is a bit of a challenge for light polluted skies. It took awhile to find this. -- Optional related URLs: http://www.geocities.com/kentauruscom/NAR_home.htm ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Sun Apr 8 05:40:47 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 8 Apr 2007 05:40:47 -0400 Subject: (IAAC) Obj: M3 (NGC 5272) - Inst: Brennweite 12.5 inch F/4.1 reflector (homemade) Message-ID: <20070408094047.14228.qmail@sedna.atmob.org> ---- Observation Poster: Steven H.

Class: VI Constellation: Canes Venatici Data: mag 6 size >10 ' Position: RA 13h:39 DEC +28:c. 40 Description: Low power (25, 80) shows an asterism of three stars (mag 7? to 9?) surrounding this hazy object, noticeably brighter than M 53 (my observation of April 6, 2007 at c. 2130 UT, with about the same seeing as tonight-which I left out of the log!). Also noticeably larger. I note a glow around the main ball of stars (over 45,000 by some counts) about an arc second away and this is probably the collected light of outliers. I do not discern outliers at any power. UHC at higher power (103 and above) gives me some sandy contrast. Averted vision shows this better and at one point I see a silver flash from one point in the middle of the ball. Light pollution is always a challenge: hop from Arcturus strraight NE after identifying with good binoculars. 200 power shows a glowing ball with little contrast but shows me the halo of light from the outliers (if that is what it is) a bit more. -- Optional related URLs: http://www.geocities.com/kentauruscom/NAR_home.htm ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Wed Apr 25 16:26:34 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 25 Apr 2007 16:26:34 -0400 Subject: (IAAC) Obj: Melotte 15, IC 1805 - Inst: Brennweite 1250mm (12.5 inch) F 4.1 truss Dobsonian (homemade) Message-ID: <20070425202634.24644.qmail@sedna.atmob.org> ---- Observation Poster: Steven H.

Position: RA 2hr:c. 30 DEC +61n: Description: I get the light glow from three locations in the object, like a semi-circular pinwheel of pairs, two SW diagonal to the two to N, NE. The gaseous background is found in the upper areas of the cluster. I peruse IC 1805 (I think). I really cannot distinguish one from the other. I get the best sight in lower power (x76) and the UHC aids somewhat in viewin the gaseous background. -- Optional related URLs: http://www.geocities.com/kentauruscom/NAR_home.htm ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Wed Apr 25 16:15:24 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 25 Apr 2007 16:15:24 -0400 Subject: (IAAC) Obj: M 13 (NGC 6205), NGC 6207 - Inst: Brennweite 1250mm (12.5 inch) F 4.1 truss Dobsonian (homemade) Message-ID: <20070425201524.18120.qmail@sedna.atmob.org> ---- Observation Poster: Steven H.

Class: V Constellation: Hercules Data: mag >5 size >10? Position: RA 16hr:c.40 DEC +36: Description: NOTE: Correction to all Brennweite entries for me on powers (may be obvious). I have been using powers calculated to my 4.8 Bresser refractor (!)Sorry. My actual powers (for focal length 1905mm) are: 47.6x 76.2x 95.25x 152.4x 190.5x 196.3x 302.3x 381x Thank you. x47 shows the two 6 or so mag stars that frame in the object to the right and left, a very good sight with the fuzzy ball at 20?diameter. A filter helps bring contrast out somewhat. Averted vision is very impressive with this object and when you use it, you get a sense of M 13's size. x76, x95 takes in the pair to the SW of the object, the 6 mag stars no longer seen. At these powers I think I see NGC 6207 below M 13, but there are a few faint glows here and >10 or so mag stars. x152 not only shows the outliers and the pair to SW very well but M13 takes on a silvery, rose-shaped appearance, gaps and clumps on the borders, and the outliers looking like bees returning to a nest. My Pl?ssel (x196) with eyecup relief takes in the enormous amount of light this thing generates: there is this glow. Locating this object w/ 10 x 50 Nikon Lookout II's shows the object looking like an approaching Klingon vessel in the original Star Trek series, what with the pair of 6 mag stars side by side. -- Optional related URLs: http://www.geocities.com/kentauruscom/NAR_home.htm ** This observing log automatically submitted via the Web from: http://www.visualdeepsky.org/enter-log.html From anonymous at sedna.atmob.org Tue Apr 17 16:02:18 2007 From: anonymous at sedna.atmob.org (anonymous at sedna.atmob.org) Date: 17 Apr 2007 16:02:18 -0400 Subject: (IAAC) Obj: NGC 3419 - Inst: 10.1" f/4.5 Newtonian reflector Message-ID: <20070417200218.23368.qmail@sedna.atmob.org> ---- Observation Poster: Brent Reary Observer: Brent Reary Your skills: Intermediate (some years) Date/time of observation: 4/16/07 03:55 UT Location of site: Rolla, MO USA (Lat 37 57'N, Elev ) Site classification: Rural Sky darkness: 6.5 Seeing: 6 <1-10 Seeing Scale (10 best)> Moon presence: None - moon not in sky Instrument: 10.1" f/4.5 Newtonian reflector Magnification: 128x, 193x Filter(s): None Object(s): NGC 3419 Category: External galaxy.
