NGC 2683 - The UFO Galaxy new

#3724137 - 04/04/10 12:13 PM

I was working on some faint fuzzy galaxies last night and was surprised by this beauty in Lynx. The list I was working on had it at mag 11, although sources on the internet list it at mag 10.6. Very bright, elongated, with hint of structure in my C11 at 200X. One of the guys next to me heard my "wow" and asked what I was looking at. As one of the more experienced observers in our club, he was impressed too.

Certainly worth a view.

NGC 2683 is one of the best early spring galaxies.

Jake:

My sources as well as two of Dave's indicates a Vmag of 10.6. What source do you have for the Vmag of 9.7?

I ask because I have seen different sources give different magnitudes on galaxies; it is not uncommon.

NGC/IC project has the galaxy at 9.6 (v). 9.7 (v) is from Wolfgang Steinicke's NGC/IC data.

Many of the B and V magnitudes you'll find online and in software programs are from the 1991 Third Reference Catalogue of Bright Galaxies (RC3) by Corwin, Buta and de Vaucouleurs. These magnitudes and many more are available at NED (see http://tinyurl.com/ygwbjuq for NGC 2683).

In the case of NGC 2683, the RC3 gives a B (blue) magnitude of 10.6 and a V magnitude of 9.7, which was used by the NGC/IC Project and Steinicke.

I just logged 2683 for the first time this past Saturday night. Much brighter than I expected. This is one I will spend more time with in the future.

I just realized in this thread there really wasn't any descriptions of the galaxy, so here are my notes from a month ago --

18" (3/13/10): gorgeous view at 280x! This detailed, edge-on spiral extends 9'x1.5' SW-NE. Well concentrated with a very bright, elongated core, roughly 3'x1.5' and noticeably mottled or dusty with brighter knots or spots near the core. The SW extension is more prominent and is easily traced to the outer tip. This extensions grow broadly to the core. In contrast, the NE extension fades rapidly after the core, so there is a sharper concentration to the core on the NE side of the core. The NE arm has a low surface brightness as it extends past a mag 13 star (close double) off the north flank. The galaxy has an unusual warped appearance with the SW and NE portions not aligned due to asymmetric extensions from the core.

Pretty much is what I see in the 12.5". I noted a few superimposed stars, and a noticeable off-center nature to the core in the short axis as well as, you have noted, the long axis.
Spectacular object.

My notes from March '09 with my 140:
Elongated,easy @ 26x. Best around 100x but 144x revealed several foreground *'s in close proximity. Averted vision stretched it out and brightened the flat core.

It's bright enough I added it to my list of the 500 best DSOs.

I just looked at it last night in my 10" dob from my club's orange zone site. I think that NGC 2683 is a wonderful object! It's quite bright, very attractive, and rises high out of the light pollution murk.

I also checked out NGC 2903 in Leo, which isn't too far away. That one is another real gem.

2903 is one of my favorites too. I'm surprised that Messier didn't include it in his list.

It was probably because NGC 2903 was discovered by William Herschel in 1784, which was three years after the final version of the Messier catalog was published. Messier, who was primarily a comet hunter, apparently lost interest in cataloging deep-sky objects when Herschel began his far more systematic surveys.

NGC 2683 was discovered by Herschel in 1788.

Superb images posted of this galaxy which curiously to me appears as two gxys overlaying with the major axis of the 'foreground dusty' gxy slightly below and rotated clockwise

2683 IS a beauty of a galaxy - slender lenticular span with good condensation through my 8". It doesn't yield details per se, but the span is so beautifully defined it doesn't need to. This object is one of those under sung show pieces, alas, in a relatively forgettable constellation.

Nice that you brought attention to it.

With blue and visual magnitudes of 10.6 and 9.7, respectively, B-V = 0.9, which is the yellow-orange color of a typical early K-type star of solar metallicity. Galaxies for which the majority of the light comes from an older bulge/halo population, and not a young, bluish disk, will be visually brighter than a B magnitude would suggest. This applies to the majority of galaxies. Even if there is something of a young disk as long as the central bulge is dominant.
