Budget? Not sure how much you’ve spent on your astrophotography hobby but you could buy two or three high quality eyepieces for likely a lot less.
Have a look at the advice section on the Tele Vue page for an eyepiece primer.

You have to decide what is more important to you in an eyepiece, e.g. eye relief (if wearing glasses you want 20mm eye relief) but Tele Vue do sell Dioptrx for astigmatism or do you prefer extra wide field of view such as 100 deg or is 82 deg plenty or do you prefer less?
Tele Vue are corrected and tested with a flat field telescope to f4. You will find they perform equally well in Newtonians, refractors and catadioptrics. In fact I’m yet to find a telescope where a Tele Vue eyepiece doesn’t perform well and I’ve used a few different types in many different telescopes.
If they are well above what you want to spend, that’s fine, have a look at their web site anyway especially the advice section as well the the section on the eyepieces as it is very informative.
