Holmes at Halloween

Posted By Joe Gafford
Here is an image of 17P Holmes taken during All Hallow's Eve in Denver. Taken 8:00 pm MDT (02:00 UT on 1 Nov.) between putting candy in Kids' little pumpkins and looking at eye candy in the scope, I managed to get this little gem.
10" f4.5 Newtonian with 1.8x tele-extender barlow.
1 minute exposure with an Olympus E-500 DSLR. North is up, a little tail to the southwest (lower right).
Enjoy! Joe.

Holmes with tail, Sunday

Posted By Joe Gafford
Darker night, longer exposure. This is a mosaic of two 5/5/4/5 minute LRGB images with a shorter exposure on top of the core for detail. 10" f4.5 Newtonian with SBIG ST-2000XM CCD camera. Taken near Deer Trail, CO. Enjoy! wink

M31 mosaic from Okie-Tex

Posted By Joe Gafford
This is a mosaic of 15 images 8O of M31 taken at the 2007 Okie-Tex starparty this past October. This was done with a 10" f4.5 Newtonian with a new tube assembly I made for it. SBIG ST-2000XM CCD camera Binned 2x2, 20/20/15/20 minute LRGB on each section for a total of more than 18 hours exposure time, including redo shots. 85% of the images were done at Okie-Tex, the rest were done at the Denver Astronomical Society's EGK dark sky site near Deer Trail, CO. An earlier less saturated image of the core was stacked-on for more detail. Processed in SB CCD Soft, Photoshop with FITS Liberator and Astronomy tools plug-ins. SB TheSky 6 provided the mosaic map for this project. Enjoy! Joe.
