Solar Disc Trifecta | HA, CaK, Gband | July 12th 2020

[MalVeauX]

Heya,

Seeing was not great this morning, but it was fairly clear for once, so I had to at least take a look. Went for a trifecta of full discs of the upper chromosphere, lower chromosphere and photosphere. Everything from a masked ED80 at 60mm aperture with an IMX183 sensor binned to 2x2 (trying to work through the grid artifact stuff). A single dark filament was present on the disc worth looking at, so I captured that on in moderate resolution HA with a 120mm.

ED80 Refractor
+ Lunt Cak B1200 + IMX183
+ Solarmax 60mm II Etalon + IMX183
+ Edmund Optics 430nm Gband + Baader ND3.0 + IMX183
120mm F10 Refractor
+ Baader Red CCD-IR Block filter (D-ERF) + 1A HA Filter + 10mm Blocking Filter + 290MM

Very best,
