August 2, 2022: Solar Full Disk Mosaic in H-alpha

[michael.h.f.wilkinson]

Shot a full disk mosaic (17-pane) with the APM 80 mm triplet, ASI174MM, Beloptik Tri-Band ERF, Baader TZ-4 4x tele-centric lens, and Solar Spectrum 0.3 Å  H-alpha filter. I first got one set of 1000-frame SER files, and took some longer ones of the huge arcing prominence. The seeing turned better during the imaging session, so I shot a second batch of 1000-frame SER files which turned out much sharper than the first batch. This mosaic is the result of the second batch.

Part inverted + pseudo-colour:

The huge prom on the left is stunning, but there is a little bright patch on the righthand limb which was showing a lot of activity. I shot it repeatedly and I think there are some post-surge loops developing there in this lat shot. I will try to process the other shots later, and create a little sequence.
