Best eyepeices for Celestron CPC 925?
Yesterday I picked up my new Celeston CPC 925 from Andrews Communications. By 8pm it was assembled and had first light - which was the first-quarter moon - so far so good. At least the optics are ok. the moon is great for aligning the finderscope for the first time. I then spent the next hour trying to do an alignment. In an ideal world this should be straight forward but I was doing this on the balcony of my unit that only has the north and west sides open to the sky!
In the end I gave up and decided to change tack. I got out my motley collection of eyepieces and put them through their paces and instantly my main problem was clear - when changing eyepieces there is a lot of turning of the focusing knob. Now this wasn't so bad on my dob, but with the SC it is more of an issue.
Doing my research on the web, it became apparent that what I need is a collection of eyepieces that are parfocal. i would like some feedback please from other owners of similar scopes as to their experience and recommendations.
I guess the other issues is whether it is worth investing in a 2" prism diagonal together with a say a good 31mm eyepiece. Your thoughts?
