Relating to the 210...I was wondering if anyone else noticed that the secondary shadow could be perfectly centered on one side of out of focus...then slightly out of center on the other side of out of focus? As I remember, I had a similar peculiarity with my 180. I was wondering if I should eliminate my diagonal when collimating? Any thoughts about this would be great! Scott
210 Collimation quirk??
