I took these last night, 3/4/2020 from lancaster, calif usa.
15-80 second exposures I believe at iso800
through my C8 on my EXOS-2GT mount.
DSLR camera, zwo guide camera, celestron off axis guider.
this time I had really good guiding I think, at least the graph was pretty flat throughout.
this one is after the stacking..
and then after some playing in photoshop...new at this..
and this is my graph in PHD2 when i was guiding on a good star..
