Quark's BF on Lunt diagonal

Post by soulvagabond »

Daystar's bf is about twice the size of Lunt's in my BF600 diagonal, I briefly swapped them. The picture is awful, with Quark's bf in place of Lunt's little red glass. Double limb and barely any h-alpha details visible. What's strange, is that in Quark bf placed with the mirror side forward, in Bf600 diagonal, it's the other way around, the red glass is facing forward. My Quark is dead, I'd love to fully utilize the parts from it...

What is wrong with your Quark?

Definitely the etalon and not the blocking filter that is trashed?

Previously, was double stacking the Lunt, with the Quark, with the Quark's bf unscrewed and it worked well. Now it doesn't

Searched a bit on the forum, the last post of this thread gives some idea, why it doesn't work well: viewtopic.php?t=21856
