Can I double stack Quark + Lunt LS50THa?

Post by teldar_paper » Sun Sep 03, 2017 11:14 pm

I have the Lunt LS50THa with B400, I thought I could solve 3 problems:

1. See more disk detail
2. Have a bigger blocking filter for imaging
3. Let me use more comfortable, longer focal length eyepieces (right now I have to use uncomfortable 4mm Plossls for high mag)

by getting a Quark Chromosphere as a double stack unit.

From what I'm read online, I just have to replace the B400 with a regular diagonal & put the Quark in it... anything wrong this plan?

It will be extremely dim for a start. I tried once with a Lunt 60 and it didn't work.

I had to fiddle with a few extension tubes/diagonals to get it to focus, but looking through it at 100x magnification was awesome! I can't imagine that the "native" front-mounted DS etalon could be much better than this. I'll still have to get the feathertouch/moonlite focuser to better handle the added weight of the Quark.
