DO NOT POINT YOUR CAMERA/TELESCOPE OR LOOK AT THE SUN WITHOUT PROPER SOLAR FILTER AND CHECK THE FILTER FIRST TO MAKE SURE THERE'S NO DAMAGE/HOLE!!!!

We can do the Moon the Sun is roughly the same. I take this image using burst mode 333 frame were taken and stacked 65 frame.

Camera : Sony A7C

Lens : Svbony SV545 203mm f/4.5

Filter : Thounsand Oak Solarite

Camera setting

Shutter speed : 1/4000s

ISO : 640

White balance : Daylight

Drive Mode : Burst - Hi

Image Quality : RAW uncompressed

Take a lot of image

Just like the Moon take as many as you can the Sun will drift accross the screen do not worry.

Processing the image

PIPP - To align the Sun to the center to the image so stacking software don't mess up the stacking.

• No convert to monochrome
• I crop the image to reduce the file size

Siril - Stack

• Amount of frame stacking is up to you i stack 65 out of 333

Registax 6 - Sharpen

• Wavelet linear

Darktable - Final touch

• Tone curve
• Local contrast
• Contrast equalizer
• AgX

 

I don't need to seperate the stacking to avoid rotation issue because i keep my camera leveled decently this time.

 

Summary

 

PIPP - Centered

Siril - Stack

Registax 6 - Sharpen

No tripod no star tracker well it's possible. I taken this image using burst mode 271 frame were taken and stacked 60 frame.

Rawtherapee - To make to colour is as intended as you want.

• White balance use Camera/Daylight
• No capture sharpening

PIPP - To align the moon to the center of the image so stacking software don't mess up the stacking.

• No debayer
• No convert to monochrome
• Cropped the images to reduce the file size

Affinity Photo 2 - Stack 

• Stack 10 image at a time to avoid software having alignment issue with extreme rotated frame.
• Stack the stacked images together
• Use Scale, rotate and translate
• Check Automatically Align Images

Registax 6 - Sharpen

• Wavelet - linear

Darktable - Final touch

• Tone curve
• Shadows and Highlights
• Contrast equalizer
• Local contrast

There's many good technique to mitigate the rind artifact i might give this a reprocess in the future.

For stacking Astrosurface and Autostakkert! should work too and may not need to seperate the stack i didn't test this.

I have successfully fix the rotated sub frame with ImageJ but can't find a way to export 16-bit TIF file.
