AR2794 Sunspot, Mottling, Faculae, Cells | HA, WL | Dec 22nd 2020

[MalVeauX]

Heya,

It was simply too cold for my Florida-behind to go out this morning, windy and freezing, so I waited until it was mid-day, seeing was terrible (for my norm). So, I went with a courser image scale and it gave me a good opportunity to use a new aperture mask that Dave made! Thanks Dave! I masked my 120mm F8.3 to 100mm F10 +/- 1mm and it worked great for getting things critically sampled where I wanted them in variable seeing conditions this afternoon (after 12pm, which is late for me!). AR2794 is pretty interesting, it's not throwing off big flares or explosions, but it has a great big faculae network around it in the photosphere, great mottling as a result in the chromosphere, and is a rather large area. There's another active area tailing right behind it that was throwing up surge prominences at the limb.

Upper Chromosphere with Sunspot, Plage, Filaments, Mottling, Surge Prominences (B&W, Colored, Alt B&W & Alt Colored):

Photosphere with Faculae & Convection Cells (B&W, Colored):

Equipment:

120mm F8.3 refractor masked to 100mm F10 with Dave's 3D printed aperture mask insert (Thanks Dave!!)
+Baader Red CCD-IR Block Filter as sub-aperture internal D-ERF -> HA Filter + BF + ASI290MM (HA)
+Baader Red CCD-IR Block Filter as sub-aperture internal D-ERF -> Baader ND3.0 Filter + ASI290MM (Photosphere)

Very best,

Lovely you got the new activity. Still clouded here.

After seeing your post I gave AR2794 a quick peek around 1pm.

I took a few single images with my Canon but haven't downloaded them off the card onto my computer. Probably do that in the morning.
