2020-06-11 AR12765 (CaK/HA)

[JochenM]

After not having seen the sun for quite a while, the sky all of a sudden cleared up tonight. Don't need to tell me twice, so I immediately set up outside while it lasted. All things considered, seeing was fairly decent as well.

This was the first time (and honestly, probably the last as well) that I've been able to take a look at AR12765. It's still quite apparent, with a nice big spot with a clearly visible umbra/penumbra and a nice filament.

Setup:

CaK (FD): 80ED (stopped down to 60mm), Lunt CaK b1800, IMX178.
CaK (closeup): 150mm f8 achromat, Baader Blue CCD filter as sub-aperture ERF, Lunt CaK b1800, IMX174.
HA: 80ED, Quark Chromosphere, Baader 35nm H-Alpha filter as sub-aperture ERF, IMX174.
HA (High Res): 150mm f8 achromat, Quark Chromosphere, Baader 35nm H-Alpha filter as sub-aperture ERF, IMX174.

Thanks for looking!
