Sun December 16 reworked using AstroSurface

 

My image of the Sun in H-apha from December 16, 2022 is reworked using AstroSurface. The software is able to stack my SER movie and to edit the result using deconvolution, sharpening, ... Normally I stack my pictures using AS3! and editting with IMPPG and CS4. The result is very promissing.
The picture shows an active Sun with different prominences.

Setting: SolarMaxIII 70/400 f/5.7 DS, ASI290MM

Mars - Edit with AstroSurface T7 Titania

My earlier images of Mars (December 12th) are reworked using AstroSurface T7 Titania - see this link http://astrosurface.com/

This free software has the ability to stack and to edit the images inclusing, wavelets, sharpen, deconvolution but also RGB splitting and merging. So far the software is an added value on the once I'm currently using. 

Setting: TAL200K f/8.5, ASI224MC, Barlowx2, ADC, IR/UV blocker
