Doppler effect Sol'Ex Sun September 10

 

I made a movie using h-alpha images from September 10th, 2026.

The movie shows the sequence from the photosphere to chromosphere and back with a range of 1 angstrom. The pop up of the filament in the photosphere is due to doppler effect and the filament has a speed of 46km/s.

  

Sun September 10, 2026 - Sol'Ex

No clouds in the morning; later on clouds started to populate the sky. Still issues with Sol'Ex, mainly with the connection with Herschel Wedge and Sol'Ex. After my session was completed, I glued to connection together. 

Total Solar Eclipse August 12, 2026

My pictures of the Solar Eclipse of August 12, 2026 are reworked. I used 3 bracketing images to create a HDR image. Wavelets and HDR done using AstroSurface. CS4 next to stack and final editing.

Sol'Ex H-alpha, H-beta and HeID3

 

After more then a month, I took the time to capture the Sun using my Sol'Ex.

Seeing was moderate but with some clouds coming over.

The main challenge was the setting of the scope after usage during the total solar Eclipse.

Setting

Sol'Ex on TLAPO80/480 and ASI678MM

Herschel wedge and IR Cut filter

Sx/Sy = 1 and Tilt between 0,5 and 1° (need some more time to adjust)

Software: SharpCap, Inti, AstroSurface, CS4
