Hi Everyone.
Seeing was bad to mediocre and definitely affected the quality of the higher res h-alpha images here. The CaK didn't turn out too badly.
The highest res h-alpha was 2x2 binned at capture (shorter exposure time allowed).
Cheers.
Peter

Peter, your 115mm seems well corrected in Cak, good images in H alpha too.

Thanks, Everyone.
Raf, I'm very pleased with the uv performance of this scope. It's time to adjust the optics and push the magnification a little bit!
Cheers.

Very nice Peter. That 115mm Stellarvue seems a great performer at CaK wavelengths.
