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.

Bahtinov Focus Mask - astrophotography Celestron 4SE

The Bahtinov mask is a device used to accurately focus astronomical telescopes. The Bahtinov mask consists of three separate grids, positioned in such a way that the grids produce three angled diffraction spikes at the focal plane of the instrument for each bright image element (star).

Bahtinov Focus Mask, Celestron NexStar 4SE, Canon 40D, Spica Out of focus - the central spike is noticeably displaced from the

Bright star near perfect focus using Bahtinov Mask. Optimum focus is achieved when the middle spike is centered on the star and symmetrically positioned between the other two spikes. Small deviations from optimal focus are easily visible. Bahtinov mask, Celestron NexStar 4SE, Canon 40D

Just bought UV/Infrared Cutoff filter and tried to test it.

RegiStax 6 vs. 5 comparison - Jupiter Celestron 4SE

Here is an example of the difference between Registax v5 and v6 for Jupiter (Jupiter with Ganymede Moon and Ganymede Shadow Transit, September 18, 2010 - Celestron 4SE)

Registax v6 - Wavelet - Gaussian Initial Layer 3 Used Linked Wavelets with denoise 1 and 2 layers, RGB shift

Registax 6, Celestron 4SE, Jupiter

Registax 5, Celestron 4SE, Jupiter

Some clouds are more visible in Registax v6, the shadow and Ganymede moon looks better. So my opinion Registax 6 gives better result with Used Linked Wavelets.

Comet 103P/Hartley 2 from New York City

From the public, his discovery brought cheers. 

From his wife, it drew nothing but torrents of tears. 

"For you see," said Ms. Halley, 

"He used to come daily; 

Now he comes once every 70 years!"
