M27

This is the first time I’ve taken subs over more than one night. I took them with my canon 450 and 60mm tak on my Star Adventurer unguided. Just under half were taken on Sunday evening. Then I left the scope out in the same place overnight and throughout Monday so as not to alter the orientation of the camera. Checking focus was a challenge without altering the altitude from the previous night as I had to find a reasonably bright star on the same right ascension plane, one I could see in the live view of the Canon. It’s roughly 3.5 hours of lights, 1 minute exposures at ISO400 with bias & 45 Darks, processed in Pixinsight. Thanks for looking.

Class job. M27 looks so colourful. Did you find much focus change. I’ve been guilty of not changing focus from one session to the next (unless you took the camera off?)

Thank you. I did take the camera off, but had locked the focus knob on the scope. It didn’t didn’t look as if I needed to change the focus  at the time so  I left it as it was. I don’t have a fine focuser on the tak so getting critical focus is never that easy, not sure I have but it’s very close.  I did have to reframe it slightly though.
