Mars map - Celestron 4SE Mars image

I would like to die on Mars. Just not on impact.
--Elon Musk


Mars map celestron 4 se photo
Using TheSkyX First software founded computer simulation of Mars image at the moment of photo.
TheSkyX First Light Edition Mars Simulation


After that founded Mars Picture in Google Map

Google Map

And using Mars Map from website planetologia.elte.hu


finally can able to show Mars Terra's on the my image.


Planum Boreum - Latin: "the northern plain".

The Acidalia Planitia is named after a corresponding albedo feature on a map by Giovanni Schiaparelli, which was in turn named after the mythological fountain of Acidalia. It has been hypothesized by J.E.Brandenburg that a large natural nuclear reactor in the northern Mare Acidalium underwent catastrophic meltdown.

Tempe Terra is a heavily cratered highland region, contains a large number of small shield volcanoes and other volcanic structures. The name comes from the Vale of Tempe, a valley located south of Mount Olympus and celebrated by the ancient Greeks for its beauty.

Xanthe Terra means "golden-yellow land."

The Valles Marineris rift system is one of the larger canyons of the Solar System.

Noachis Terra - Latin: "Land of Noah"

Terra Meridiani - "Meridian Land". Astronomers had chosen a particular point on Mars as being the location of its prime meridian. Sometimes is using other name "Sinus Meridiani", literally "Meridian Bay".

Arabia Terra was named in 1979 after a corresponding albedo feature on a map by Giovanni Schiaparelli, who named it in turn after the Arabian peninsula.

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.

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.
