Three things for thinking slightly out of collimation.
1.. a very learned gentlemen (asimov) commented from the original mars video i did, that it was a little.
2.. stars don't come to a point on very high mag, they elongate
3.. looking down the focuser without eyepiece, all the mirrors don't line up perfectly. I used the cheshire tonight to line up secondary and now just have to adjust primary. Not sure how to adjust primary. I do not want to muck around with screws on the bottom of scope until i know what each one does.
I read that article you posted a week or so ago. I may take a shot if i can to show.
anyway a noobie assessment!!
