AR2866 AR2877 and Large Prom from Sydney 23Oct2021
Still experimenting with the 5X Powermate seems it might have internal reflections within the optics ?

Still struggling with this 5X Powermate seems to have internal reflections within the actual optics , I added a small black extension thinking it was the end of the chrome barrel but its still there more noticeable on Proms and edge of Sun images.. Using defocused flats helps some.

I would think a de-focused flat would only modulate internal reflections.Cliff wrote: ↑Mon Oct 25, 2021 2:15 am Thanks John,

I'm a big fan of Powermates. You might contact Al Nagler at Tele Vue about the issue. He is about the most helpful, understanding fellow you'll ever talk to. I once had an issue with a Powermate and called the technical support line and was amazed that the owner/founder actually answered. He sent me a new replacement before I actually sent the old one to Tele Vue.
