Sun H-Alpha with New AstroSurface U4 Urania

 

I reworked my images from the Sun of June 3, 2023. This time I used only one software package, AstroSurface. On top of this I used the new version of AstroSurface, version U4 Urania.

My previous image proces flow:

- AS3! for stacking

- IMPPG Deconvolution

- CS4 for fnal editing

Current image proves flow:

- AstroSurface U4 Urania

- CS4 for final editing

With my limited experience I see no real change but for sure it's more easy to use one software for processing. 

Setting: SolarMaxIII 70/400 f/5.7, ASI290MM with reducer x0.5

Software: SharpCap4, AstroSurface U4 Urania, CS4

Lights: 3000 frames using seeing monitor and using flats; AstroSurface stacking best 10%
