Prom, Plage, Filmaments & Spicules | HA, CaK Disc | Feb 11th 2021

[MalVeauX]

Heya,

Another cloudy, foggy day. But I had a moment in the afternoon to attempt a peak and do some tests with the IMX253 sensor via a Flir camera. The big prominence on the north eastern limb persists, I bet it would make an awesome animation but I couldn't get enough data with the non stop clouds to attempt that. So I just grabbed a disc in calcium and took a look at the small plage and filament chain and the larger prominence on the limb and called it a session. Seeing was rubbish as it was late morning and cloudy. But it was better than another week of rain!

 

Seeing Conditions:

Terrible seeing, lots of clouds, late morning is always bad, but it's all I had compared to rain for days on end lately here.

Equipment:

100mm F10 masked refractor
Internal sub-aperture D-ERF (Baader Red CCD IR Block filter, 50mm)
PST Etalon + 10mm BF + ASI290MM
60mm F16.7 masked refractor
Lunt CaK B1200 + IMX253

Very best,

[Knight of Clear Skies]

Superb images.
