I will be choosing a new scope for photometry later this year, a reflector, somewhere in the 8 to 10 inch range.
My question is, do I steer clear of scopes that produce diffraction spikes? I'm sure this would produce erroneous data, especially on the brighter stars...probably even on faint stars too? I've done a thorough web search and the question is still unanswered.
Any thoughts on this is much appreciated.
