Terrible corners
Is this the result of coma?
It can't be field rotation i get the same length streak no matter what the exposure. The problem only exsists in the corners, stars in the centre are sharp and round.
Used a C8 with 6.3 reducer same problem. Modified an extension tube to increase distance between reducer and camera and ended up with slightly wider field of view but just as bad a result with streaking stars.
What have i got to do to fix this problem (within affordable costs). Can it be fixed on these type of scopes or are the optics just bad on the C8.
I've heard some good reviews about the new Orion/Bintel f/4 reflectors.$799-$999. Would love an Astrograph but simply out of the question at the moment.
I'm actually happier with my wide field with my Skywatcher 80ed
Any help appreciated.
PS just had a go with my new modded camera . Woah! talk about red!
