The Sun on May 12th 2021 in H-Alpha

Here is the sun taken with a Quark Daystar Chromosphere filter. This filter captures a very narrow bandwidth of 656nm. The Telescope used was a Stellarvue SVX 80T-R refractor telescope. The camera used was a ZWO 174mm Mono Astro Camera riding on an iOptron ZEQ25GT. This image is composed of two different images. One is the Chromosphere and the other is the Prominence (The flares you see on the edge). They are then combined in Photoshop and Color is added to it since it was taken with a Mono Astro Cam.

A Mono Astro Camera has much more sensitivity and resolution than using a One-Shot Color Camera that has a Bayer Matrix on top of the sensor. This Bayer Matrix layer uses a combination of RGGB or in a different order, but the main thing is that it combines 1 red pixel with 2 green and 1 blue. A mono sensor concentrates all of the photons without the use of a Bayer Matrix, therefore uses the sensor’s Maximum capability for the image that is captured.

Each exposure was 10 seconds which included about 1500 frames each. I then took the best 20% of the frames and stacked them in a program called Autostakkert. After that, I put the final tiff images into another program called Registax6. This brought out the details a bit more using a function called wavelets inside REgistax 6. It then wento off to Photoshop to add color and tweaked a bit more to get the details out.
