AR2767's Spot in High Res | HA, CaK & Gband | July 24th 2020

[MalVeauX]

Heya,

I've been under non-stop storms for days and along came a sunspot finally. I wasn't able to even visualize it since it's appearance until this morning, I was out before 8am just waiting for it to clear my tree line and watching the clouds coming with it but managed to get just enough time to get some data in three wavelengths on the new spot. It's looking like a class H spot to me (correct me if i'm incorrect) so far. Captured in HA, CaK & Gband under good seeing conditions, ranging from 0.3" to 0.8" arc-seconds this morning. Captured with a 150mm F8 refractor with only a sub-aperture internal 50mm D-ERF for all the wavelengths (CaK was masked to 120mm F10 for seeing conditions).
