You know you are there when you start thinking in terms of EXIT PUPIL rather than Magnification..

Quote: Currently I have a 32mm Meade 2 inch, a 18mm Meade HD-60 and a Celestron X-cel 12mm & 7mm. Should I go lower than 7mm? I was thinking about getting a 38mm Orion Q70 and a 2" in the 20 range...any suggestions?

Quote:You might consider getting the secondary tested as well. It's been said that the large flats made by Meade for these scopes often had edge issues. If yours does, you won't get everything out of your 'new' mirror....Let us know what you think of the images when you get your mirror back!
Quote:As for eyepieces, I wouldn't go to a 38mm eyepiece. The exit pupil on your 32mm is already 7mm. with a 38 it would be over 8mm. As people say, you're wasting light because your eyes cannot take in that big of beam of light.My observing is done with a 27mm Panoptic, a 15mm Explore Scientific 82 degree and a 9mm Nagler. When I want more power I can use my barlow in the 15 or the 9.
Quote:No, that is not typical of mass produced mirrors...

Quote:I never noticed the diffraction spikes like that looking at bright planets in this scope before but then again....the mirror had a rough coating and was a PV 1/1.7 and a Streyl of .357. Now it's a PV 1/9.5 and a Streyl of .968. The improvement was impressive!
