Just to ad my 2 cents worth, the relatively inexpensive (especially used) Synta 100ED f/9 scopes (Celestron, Skywatcher, etc.) don't do too bad at 394 nm either:

Equivalent to a 160 mm scope at H alpha BTW... Orion ED 100 f/9, 2x TeleVue Big Barlow, DS CaK home brew, PGR Chameleon.

Hey Bob,

Do you mind expanding on this double stack CaK home brew setup? I'm really starting to feel like getting into a double stack calcium system with my 6 inch refractor since the resolution would be significantly higher than an HA system and I just really like the look of calcium.

Does your system allow you to see filaments and prominences in Calcium?

I'm curious of course what your system is and how you stacked it and how you manage the thermal energy?

Thanks!

Very best,
