CaK activity 25Jan 2022

Post by Merlin66 »

Using the Vixen 90/1000 with the DIY CaK filter (1A bandwidth). Some issues with the internal tilt need to be addressed.
Prom Images from stacks of 200 from 500 slightly sharpened.
Exposures were typically 40-60ms, a total of 10sec. :shock:
(For comparison the previous CaK I showed from the MiniSHG took only 0.004 sec :mrgreen: - the benefit of a very narrowband centred on the activity.)

The southern zone dominated by the large sunspot AR 2934.
The northern zone has a new AR just coming into view - complex with at least two larger spots. The mid zone shows the small group AR 2935?
Some very nice proms around!!!
Enjoy.

Thanks to everyone, appreciate the feedback!
Going back to the 90mm f11 for the CaK gives better resolution (in my very average conditions) but the MiniSHG is much quicker for the run of the mill full disks and proms albeit at a smaller scale.

Awesome work Ken! The CaK proms show quite a bit of detail and are not just vague ghostly fuzzies.
