Tiny AR12721 in H-alpha and CaK: Sept10

Post by p_zetner » Thu Sep 13, 2018 9:19 pm

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.

Good images, Peter. That CaK is a beauty.

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