First time out in some time again. We've had a few clear nights, but I've been either working or sick. Tonight was delightful. I've been wanting to add H-alpha time to my Leaping Frog shot from the last dark sky outing. I didn't actually journal about that one because it was very frustrating. I did manage to get some great data on this target at that star party though and tonight I made it better.
 
It's so great being able to enhance images shot from a dark sky site by shooting H-alpha data from my house. I've really been enjoying doing that and this image is no exception.
 
I was very pleased with the guiding. This new ADM hardware holding everything together is amazing. .14 RMS and nice tight tiny stars at 20 minute subs. Yeah baby! Woot!!

This is an excellent shot.
a few questions
1. What ADM hardware are you referring to?
2. How did you manage the noise at 1200secs?
3. How did you manage such successful guiding?
