Mars Celestron 4SE Telescope Backyard Astrophotography

Mars Celestron NexStar 4SE (102mm) NexImage, 2-x Barlow 



Mars Celestron NexStar 4SE (102mm) NexImage, 2-x Barlow

Video duration 4 min 00 sec (240sec), Frame Rate 10 frames/second, 2400 frames. 


Registax v6.1: 
Drizzling Optimization, Wavelet - Default Initial Layer 1, RGB shift, Resize Image 200%

Photoshop: 


Filter Unsharp Mask in Photoshop allows see more clear details which exist but still not so good visible after Registax (especially it is important for such small telescope as Celestron 4SE). But if Unsharp is too aggressive some artifact appears. So, first I decreased a little bit brightness to make possibility use aggressive Unsharp Mask. After that used Unsharp Mask which was still have some small artifacts. And smooth these artifacts with filter Noise Median radius 3. Finally I added a little bit magenta.
