Techno Stuff: 4/20/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Luminance IR 10x600secs Binning 1x1, RG 5x360secs B 5x420secs Binning 1x1, Autoguided with Atik-2HS and Guidedog from LX90, Darks Applied, Registax3, Photoshop CS2, PixInsight

Notes: This is a cluster of galaxies from Paul Hickson's Catalog of Compact Galaxy Groups. I've counted seven galaxies so far and will be putting up a labeled chart later. There's a substancial green halo around the large yellow star which you can see in the full sized image. I don't know if this is real or an artifact caused by optics.

Techno Stuff: 4/16/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Luminance IR 12x300secs Binning 1x1, RG 6x300secs, B 6x360secs Binning 2x2, Manually Guided from LX90, Darks Applied, Registax3, Photoshop CS2, PixInsight

Notes:One of my first color images for some time because I finally had several clear nights for a change. :>)

There are a couple of small galaxies in addition to M101. I think the small one directly below at the edge of the frame is NGC5477 and I'm not sure about the one located in the upper left.
