Solar Discs & Features | HA, CaK, Gband | Feb 23rd 2020

[MalVeauX]

Heya,

Woke up to a blue sky so figured I'd see what our sleepy start was doing. Not much going on. A filament, a prominence, nothing grand. So I did some full discs in HA, CaK & Gband to show the upper & lower chromosphere and photosphere. Seeing allowed a brief look at the chromosphere at a finer scale before the clouds rolled in.

Colored:

B&W:

Seeing Data (poor!):

Equipment:

Very best,

Great set. Blowing a gale here so no chance of any solar for me today.

Nicely captured.
