CaK and very large filament 5th Dec 21

Post by Merlin66 »

Testing some filters with the MiniSHG....
On CWL (K3) (3933.7A) the plage and chromospheric network shows well and also the very large filament down south.

Moving towards the violet (K2v) and the filament is still visible.

When moved to the red side (K2r) the filaments fade and the brightness of the active areas is enhanced .

Stunning images Ken, that SHG is the business. The images you have been posting CaK are a reference. They've certainly been giving me some ideas for tweaking my CaK filter for next year. I know I can't get the tight bandpass of the SHG, but I think there may be gains to be had on my filter system yet.
