Great gallery of pictures! - looking at your planetary nebula photos. Hope your observatory has less light pollution than my DC area location. Looking forward to trying a few of these like NCC6781 or Abell 39.

Great pics.

Leon Palmer from Rigel Systems said you might be able to help me. I'm trying to solve a nSTEP focus issue with SGP using temp compensation. Here's my setup: 11" EdgeHD, focal reducer, OAG, ASI1600, nSTEP focuser and I’m running SGP. I finally set up temperature compensation in SGP for my Rigel focuser, where my temp comp is 82 steps per degree. Since I'm using an OAG, I've discovered that when the focuser moves during the temperature compensation the stepper motor torque causes PhD2 on many occasions to lose lock on the star and my sequence will terminate. I've increased the star search size in PhD2 to 50 pixel (the maximum) and it still fails. Of course, SGP doesn’t pause guiding during temperature compensation temperature changes like it does during the standing “V-curve” process. What's do you think is the best approach to reduce the jitter during the temp comp stepper motor movement so that Phd can continue to guide while using an OAG? In the GSUSB nSTEP focuser control window there's a "Steps/sec" value that exists but it doesn't seem to be editable. I would think slowing down the stepper motor during the temp comp would be the best. Any ideas?

Saw the announcement about Byron's imaging get-together on Saturday while cruising the NOVAC page, and thinking your group might help with a question...albeit, not about astrophotography.

I'm looking at getting a DSLR. I'd like to find a model that will accept my old film SLR lenses.

I currently own a Minolto X-570 (circa 1983) with the the original 49mm lens. In addition, I have a Vivitar 70-210 (w/ 1:1 Macro) and a Vivitar 28mm WA.

Any idea how to research current cameras to see if my current lenses will fit the new camera bodies?
