this is a Single 1731sec shot at 100iso with my 6D thru my 8" Astrograph Newt. Guided on iEQ45pro Mount.
Taken back in Nov 2016.
Cold Nov night, Guiding was excellent. Its was getting late and i was getting tired. I set up BYEOS and went inside, I fell asleep
woke up 30 min later went to ck on my rig. BYEOS was locked up.
I unplugged everything, cover the scope and went to bed, I found this on the camera the next day.
This a cropped edit thru Pixinsight.
