ASTRO: NGC 6745
NGC 6745 is one of my favourite summer galaxies (or group of galaxies to be
more precise), so I reshot it in July. The image does not look too sharp, but on the other hand you need good seeing to get a sharp picture at 0.6 arcseconds/pixel. Taken from the middle of Berlin with a 10" Meade ARC at f/9 on a G11 mount, SXV-H9 camera, 36x5 minutes for L, 3x5 minutes each for RGB. The picture can also be found at http://ccd-astronomy.de/temp2/6745colourgut.jpg Stefan |

Didn't get the detail you have. I had a few nights this summer of seeing that would have supported 0.5". I should have gone for it. Wasn't thinking but Arp galaxies at the time. Odd that this "one" didn't make his list. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
