Lovely Image. I do (casually) wonder what the arc sec resolution limit
solar scopes is... Some variation on the Dawes' Limit... Mr. Nyquist? :)
How big an aperture is still beneficial for an HA scope... CaK scope etc.

Here's e.g. a stopped down (65mm only) barlowed TAK CaK setup:

Might effect any aspiring purchaser of front mounted ERF's though! ;)

My honest, and somewhat painful opinion is, even though I don't dare to think about it, that I made practically as good images with my TS65Q and Quark than now with slightly more expensive 106ED, 110mm ERF and Quark.

Here's something taken today:

My directions are messed though and need to fix that in next images..
