If I bought this, I don't want the 18mm UFF.
I have pairs for a bino viewer, chosen for the eye relief I need;
Vixen LV 18, 20, 25, 8-24 zoom
Meade HD-60 25mm
Nikon NAV SW 17.5mm
Would all those come to focus?
I have a single APM 24mm UFF & 11, 15 & 18mm Delites that I could buy a twin for.
Taking a plunge to 90° bins, I don't want to gave to buy more eyepieces, just for them.
