Mars Celestron 4SE Telescope Backyard Astrophotography

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.

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).

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

Saturn NexStar 4SE RegiStax 6 NexImage Bahtinov mask and Vibration Suppression Pads

Saturn April 21, 2011. Weather was not good - it was windy and partially cloudy. To suppress vibration I used Celestron Vibration Suppression Pads. To made better focus - used  Bahtinov focus mask.

Comparison UV/Infrared Cutoff filter vs. without filter - Celestron 4SE NexStar NexImage

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.

RegiStax 6 - Astrophotography Saturn - Testing new version v6



RegiStax 6 release 2 April 2011
Just downloaded the new version and tested it.
Installation was very simple and no problem for Vista. Interface is simpler and more intuitive.
I had some problem with multi alignment in version 5. In RegiStax 6 it works as magic -- no issue. New function - Linked Wavelet Layers -- is great! Speed fantastic. This is major improvements which allow make more experimental settings and find best parameters for final image.

Thanks for RegiStax all people who created, develop and support it! It's amazing free product!

For Saturn observation I used Celestron 4Se telescope, Barlow 2x, NexImage.
Hope it video helps and gives you ideas what you can do with Registax.
