AR2791 & AR2790 | HA & 395nm | Dec 8th 2020

[MalVeauX]

Heya,

Seeing was not great today, but was able to gather some data through lucky imaging of AR2791 (spotless) and AR2790 (small spot still). Seeing limited my resolution in short band 395nm but was still able to get something to look at that was passable, along with a quick panorama of our AR's in HA.

Seeing:

Equipment:

150mm F8 refractor (395nm)
Baader Blue CCD-IR Block (internal sub-aperture D-ERF) + Baader ND1.8 + Altair 395nm +/- 7nm filter + 2x barlow + ASI290MM
120mm F10 refractor (HA)
Baader Red CCD-IR Block (internal sub-aperture D-ERF) + PST Etalon + 10mm BF + ASI290MM

Very best,

[Pete Presland]

Superb set of images.
