Nice setup Ken,
had a look into spectroscopy just using the filters s100 I think it was on youtube haven't done anything about it though, yours looks a little more serious.

Ouch 5x5kg thats three more than i have now.

I've only just begun about a year but not a lot of actual sky time with smoke and clouds . Now heavy icy winds.

The 2" rear cell threads are the same, so it should fit.

The C11 with all the "extras" needs 5 x 5Kg counterweights
