NGC7023 - Iris Nebula - 10" Reflector

[JonCarleton]

I've not posted in a while.  Perhaps I'll get back to it now.  Here's a 400 @ 30 second subs image of NGC7013 (Iris Nebula) with my 10" reflector and a ASI178MC one-shot camera.  Imaged with SkyChart/CCDciel/PHD2, Stacked with Siril and processed in PI with GIMP touch-ups (all Linux).  I do use ASTAP for both guiding during imaging and grading the images to reduce the time I have to spend "blinking."

you have some super detail there...I suspect you have some deeper detail still hiding..... 30mins is a long sub length for a cmos have you thought about trying short subs?

Yikes!  Typo.  My apology.  30 SECOND subs.  I'll edit.  But yes, there is some more detail, however exposing it also exposes some significant noise.  I probably need as much again in overall exposure to be able to do justice the dark bits of the nebula.   You can tel they are there, as they cover up the stars in the background.
