Joe, I autoguide. I really have my Atlas EQ-G Maxed out with this 10" OTA. I have rebuilt the mount and replaced the worm bearings with high quality ceramic ones along with cleaning, re-greasing, and tweaking out the gear tolerances to get the mount to perform under this much weight. I use a little 60mm Meade refractor with a modified logitech quickcam pro 9000 to guide with. PHD guiding is the software I use. If you go here http://www.rankinstudio.com/astro and click on "equipment" you can see the guider mounted on the OTA with the webcam attached :) I followed the instructions by Gary Honis here to do the modification of the webcam. http://ghonis2.ho8.com/Pro9000a.html I just finished processing M51 from Wednesday night, and I also have to finish up M78, also shot Wednesday night :) Cheers, David Joe Bauman wrote:
David, I've so astonished by your astrophotos. Amazing. Do you guide them or does the mount work so well you don't need guiding? Thanks, Joe

Great Image David! Nice job using the shorter exposures to bring out the core area. The processing looks spot on.
