I've been zooming in on forum users images taken with 10N/12N.
All of you have better collimation than me.
Do you get that good collimation only with glatter and eventually tublug?
Sofar I've recentered center marking (was 1.5mm off) I use a perfectly collimated glatter laser and tublug.EXTREMELY CAREFULLY)
I will also use catseye autocollimator soon.
I would appreciate any tips any of you can give me because I'm nearing desperation.
Mechanically I Think all is appropriately tight.
My collimation error is pretty much constant over whole sky and does not depend on mount-error (same error even with 0.5s)
Sharpness isnt spot on either I know ( an 41cm RC at same location got seeing of ~1.5') that night.
Here is an example, pixelscale is 1.36'/pixel. ASA N10+atik460 bin1, 0.95 wynne
