Help - I'm getting eggs and doubles and L's
Hi all,
I need some opinions or advice on why I'm sometimes getting eggs or doubles or even L shaped smudges in my images. Only noticed this in my last 2 nights. Other times my stars have been round and no worries. Happens whether exposure time is 1min or 2mins. Setup each night was 2 rounds or star and polar alignment, and seemingly spot on using the Synscan polar alignment function.
Weird thing is that I might take say 8 images, and some will be okay, and others distorted. Using an intervalometer, focus lock on, everything tight, no wind, no dogs, no touchy etc.
Only environmental difference to previous sessions was much colder weather.
Setup is a Skywatcher ED80, EQ5 goto mount, Hotech FF, and Sony a6000 DLSR.
Any thoughts?
Jim
