So just made the transition from using my 70-200mm nikon lens to a Meade 70mm astrograph quad. Last night I got a few hours to test it out. However, looking at the results this morning, there are uneven and pronounced cross shapes on the brighter stars. It is evenly occurring across the whole frame My question is, is the star shape in the attached image considered acceptable, or is this scope out of adjustment in a significant way? Thanks for any input; I appreciate it.
