Welcome back, John!Wow! I'm amazed this thread is still going. Glad to see so many of you have gotten into astrophotography. (Heh, it's consumed me for the last few years...went all in on AP, so much so that I sort of wrapped my 600mm f/4 L lens in so much astro-related gear I couldn't really use it for anything else.)
Some nice stuff here, though, guys.
While I don't use Canon cameras anymore, as I switched to dedicated, cooled, mono astro cameras a while ago, here is something to get this thread going again:
"The Great Wall", part of "North America" nebula in Cygnus. A total of 24 hours of integration, acquired with an ASI183MM Pro camera, cooled to -15C, with AstroDon Ha, OIII and SII 3nm narrow band filters. Acquired with an Astro-Physics Mach 1 GTO mount and Sequence Generator Pro for automation.
Thanks, Graham!Hi Jon.
As is usual from you, 2 very good shots. For the uninitiated amongst us (me) could you decifer the jargon please, I have no idea to what you refer with all the letters. Thanks.
