Tele Vue Radian 3mm
Looking to fill a magnification gap for planetary observing.
3mm is an uncommon focal length these days so looking for one of these older models.
Note that I already have a 3.5mm equivalent (with a Powermate) and 2.5mm would give too much magnification.
I'm specifically looking for 3mm to pull out the last bit of detail on good nights.
Cheers.
