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

Saturn – April 21, 2011

This planetary image of Saturn was captured using a Celestron NexStar 4SE and NexImage planetary camera. Observing conditions were challenging — windy skies with intermittent clouds — so several techniques were used to maximize image stability and focus accuracy.

To reduce vibration from wind and mount movement, Celestron Vibration Suppression Pads were placed under the tripod. For precise focus, a Bahtinov focus mask was used before recording video.

Even with a small telescope like the Celestron NexStar 4SE, good planetary results are possible when focus, stability, and processing are handled correctly. Using a Bahtinov mask for precise focus, vibration suppression pads to reduce shake, and proper RegiStax 6 processing can make a bigger difference than aperture alone. In many cases, careful technique with a smaller scope can outperform a larger telescope used without attention to these details.

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

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.
