- 15" F/4.5 Dob
- I currently have this Binoviewer from Denis
- A pair of Zeiss E-PL eyepieces
- 2x Powermate to let the BVer reach focus
That combo of optics has given me some wonderful views, but I am craving more magnification.
The fundamental problem is that the BVer does not have individually adjustable diopters, only the eyepieces themselves do. As I prefer observing without glasses, I *need* individual diopter adjustment of some kind. I've tried pulling an eyepiece out part way, and the reality is it's just too finicky to do that accurately (holding it, tightening down the locking collar etc), so proper diopter adjustment is a must-have.
Given the BVer doesn't have diopter adjustments, my options are a bit limited as I have to stick with the Zeiss eyepieces I currently have and then use different barlows to change magnification, but a 4x powermate is a bit too much power for my skies. I would need something between 2.5x and 3x. And ideally something I can use the quick bayonet mount to switch between.
An alternative is to sell the BVer and go with something like a Denk which does have individual diopter adjustment as well as a powerswitch. But that's going to be more costly, and I've heard it doesn't hold collimation quite as well as the Zeiss-based BVer I currently have.
