Dynamic Sun with huge prominences

This morning I took some pictures of the sun using my SolarMaxIII (H-Alpha). Within a timeframe of 16 minutes the shape of the prominences changed dramatically.

For the first time I used flats for H-Alpha by using a plastic bag and adjusting histogram by changing the exposure time and gain  within SharpCap Pro. 

The SER 16bit file was stacked using AS3!. The resulted TIFF16 file was adjusted in IMPPG and CS4. Color was added in CS4 : Red 1.33, Green 0.44 and Blue 0.2.

Sun(day)

Observation of the Sun this morning with good seeing conditions.

All images taken with TAL200K f/8.5. The sundisk was imaged with ASI2600MC and sunspots AR2993/94 with ASI290MM.

Software : Sharpcap, AS3!, IMPPG, CS4.

IMPPG Software and Sunspot AR2993/94

 

I'm using IMPPG software for processing my solar images. See also this link for more information. It executes Lucy-Richardson deconvolution with great results.
So, after stacking my SER 16bit movies, I'm opening the Tif files in IMPPG. The result is a sharper and brighter Tif (or PNG,..) file which is finally edited using CS4.

Sunspot AR2993/94

No time during the week but this morning I made some time to capture the huge sunspots. Image of

H-Alpha Prominences

On Saturday morning, April 16, 2022, sunspots AR2993/94 are on the sun's limb causing changing prominences. Within 30minutes the scene kept on changing.

Setting : SolarMax III DS/BF15 70/400 with ASI290MM

Software : Sharpcap (Pro), AutoStakkert3, IMPPG, CS4.
