I have just re-acquired a pair of 12mm pentax orthos.
i have a denk std with SCD holders in Tak 128.
i've just viewed the moon and whereas i normally have no problem merging the images, i seemed to have a little trouble.
does anyone use .965 inch eyepieces? normally these ep's are not a perfect fit in their 1.25 adapters and get slightly offset when the adapter locking screw is tightened.
am i right this can decenter the eyepieces in the binoviewer and cause merging issues?

also i just tried a pair of 6mm 1.25 inch orthos and just cannot merge at x260
are these too small in fl?
