I have been imaging for over 50 yrs, but always using reflectors or
SCTs; decided to try with my 80mm achro guidescope, and got these
strange aberrations.In the first sub the left side aberrations have lines
through them. I can only think that using the diagonal might be the
problem. Please disregard the star elongation; I was only playing around,
and didn't bother with accurate PA. I'm confident that someone will know
straight away what the problem is. Thank you in advance.
Rather than start a new thread about an old chestnut, I'll mention
another problem while I'm here. Since I updated my Synscan to 3.35
The scope hunts backwards and forwards every time it reaches a new
target. I remember other people having this problem, but can"t
remember what the outcome was back then.
