AR 3031 and 3037 in three different filter (20220616)

Post by Sergio Alessandrelli »

I made a comparison mosaic of the same solar region (AR3031 and AR3037), shot with three different filter:

- Baader Ca K-line
- Lunt Calcium module 2.4A
- SolarSpectrum SO1 0.5A

I used always a William Optics FLT132, 2x-4x barlow/telecentric lens, a Baader solar wedge for the Baader CaK filter and a Baader D-ERF for the H-Alpha filter

Full resolution and data on:

Bye ;)

That's a lovely comparison and trip through the solar atmosphere :bow :hamster:

I can move this to the main Solarchat area if you want?
