What did I bugger up?
I did a mirror clean and collimated my 8” skywatcher dob.
Went outside tonight and both Saturn and mars are a blurry disc with no surface detail and I cant get a good focus on any eyepieces..
The Orion laser collimation is right in the middle for both mirrors.
(Fair Bit if god rays too) - I had better viewing before I did the clean.
Have I managed to damage the mirror? 😞
