Re: Need help deciding between Motic BA310E & Panthera CC

Motic builds scopes and optics for the “large” names.

Christian (the German Motic and Zeiss seller the link is referring to) has a good reputation in guiding his customers.

Olympus BH2 objectives require color aberration compensation via the eyepiece.

Re: U-PCD compatability with BH?

Re: Olympus FHT

Objectives are matched to eyepieces. So (in general) Nikon objectives require Nikon eyepieces (from the same “age” period), Olympus will require Olympus. Olympus objectives from the 160 mm tube length era are only PARTIALLY corrected for lateral chromatic abbreviations, the last part of the color co...

Re: What is face contrast?

In general, centering/phase telescopes work across brands. You do need to match up tube diameters. The new kits are typically meant for standard tube sizes, with a couple adapters to fit 30mm and 30.5mm tubes. I've seen a couple cases where an oddball model of phase telescope wouldn't focus properl...

Re: Olympus BHA plastic type

Apologies, missed your scope is a BHA not a BH2.

Do you have a picture plus some size measures?

There is a small chance they reused some of the basic parts when upgrading from BH series to BH2.
So if we are lucky the BH2 condenser drive part fits the BHA :?:
