It just means I'm outside for the entire session, rotating the camera, changing the filter on the slide, tweaking the focuser and collimation, checking for dew, launching another live stack. No retreating indoors for me!

That's a great way to do it ...?

Hi,
My approche is more manual. With my 20" f/4 Obsession and CMOS camera (ASI294MMPro), I take 5 minute live stacks, with 2 second exposures for each filter then manually rotate the camera using a graduated sale. I have written a program that tells me the amount of rotation needed for each interval. I still have some cropping to do but get a result that I am happy with.

You need derotator software for the rotator.

I had tried a Pegasus Astro field rotator (the first version) but could never reach focus with all my other stuff in my image train (like starizona nexus reducer/corrector). I ended up selling it before I engineered adjustable truss poles for my 18¡± astrosystems dob. I may try ?again and ?get a rotator with a thinner profile. Until then, I just crop out the rotation artifacts. I am only doing EAA using sharpcap so I am not looking for perfection.
