Tony,
I just noticed 3 minute unguided subs
What’s your secret in maintaining perfect round stars with 3 minute subs and only relying on tight PA on your AZEQ6 ?? Also frame rotation ?
Best I can manage on my EQ6-R at 1000mm focal length is 60 or 70 sec ( PA error just under an arc minute ) before stars commence to distort. Guiding for me is a must.
