Hallo Leute!
Bin gestern Nacht ueber eine Gruppe recht heller Galaxien im Sternbild Hydra "gestolpert" <img src="/phpapps/ubbthreads/images/icons/laugh.gif" alt="" /> . Die Gruppe ist nicht mal im Deep Sky Observer's Guide beschrieben, was mich sehr verwundert hat, denn diese Galaxiengruppe ist echt erwaehnenswert. Die Objekte befinden sich bei RA 0856, DEC -03, Uranometria 114. Beobachtet habe ich mit meinem Obsession 15", Seeing 8 (10 best), Limit ~6mag.
Hier mein Bericht (sorry, nur in Englisch):
This group of mostly fairly bright galaxies is surprisingly not listed and not described in The Night Sky Observers Guide by Kepple/Sanner. I ran into the group when I first looked for NGC 2713 - the only galaxy in the area plotted on Sky Atlas 2000. As I saw another bright Gx next to 2713 (ie NGC 2716), I opened Uranometria and found the listed group of galaxies just a few degrees south of 2713/16. I was stunned when I moved the scope to the group, finding a number of bright, closely located galaxies - all within ~1°! All but the 2 faintest members were visible at 131x. For more detailed observations I did use the 5mm Nagler, 342x.
NGC 2695: 11,9mag, 1,7x1,2', bright, oval, approx 1,2x1', non-stellar core.
NGC 2697: 12,3mag, 1,8x1', bright, oval and slightly smaller than 2695, non-stellar core.
NGC 2698: 12,6mag, 1,4x0,6', fairly bright, oval, brighter towards center.
NGC 2699: 12,6mag, 1x1', same brightness as 2698, round.
NGC 2702: 15,2mag, 0,5x0,3' very faint smudge, AV only, no details.
NGC 2706: 13mag, 1,8x0,6', faint, appears edge-on.
NGC 2708: 12mag, 2,6x1,3', bright, biggest member of group, features a bright core and extended 2x1' halo.
NGC 2709: 13,7mag, 0,8x0,6', faint and visible only with AV. Not as difficult as 2702. No details.
UGC 4672: 13,9mag, 0,8x0,7', very faint small smudge. Requires AV.
Clear Skies!
