At It Again
Even though I have almost a complete set of Morpheus eyepieces which was preceded by the Hyperions which were preceded by a set of ........, which were pr.......... I have now put together a small collection of Celestron Ultima Edge eps that I can use as an anytime comparison, a shootout between them and the Morpheus when the notion strikes me. I like their size compared to the Baaders, their performance out to the very edge, I like the comparison thought but don't get me wrong the Morpheus are still my top. Its my never ending style so here I go again, lol !

Re: At It Again
I have not used any of these flat field eyepieces so far but I came across his comment from Don Pensack:
Bear in mind the 10mm is the odd man in the series, with only a 60° field, and isn't as well corrected as the longer focal lengths (it has fewer elements internally). I wouldn't recommend it for anf/ 5 scope.
Hopefully it will works well for your intended telescope.

Re: At It Again
I briefly had APM 18mm version and it was a very comfortable EP . I wish smaler FLs had better eye relief though.

Re: At It Again
I have no fears it won't, I am not a perfectionist type of observer. 5 elements is good enough as is 60°, I owned a set of Xcel LX's which were excellent in their own right.Lady Fraktor wrote: ↑Sun Apr 16, 2023 6:10 pm I have not used any of these flat field eyepieces so far but I came across his comment from Don Pensack:

Re: At It Again
One additional note: the 10mm is really a 10.5mm if you are using the focal length to calculate magnification.
