Tonight, I would like to show you how I processed my recent Mars photos. The RRGB (Red-Red-Green-Blue) technique is applied. All photos are made with a user friendly One-Shot-Color WebCam (model: TIS DBK12 USB)!
YES! You can increase the resolution of your Mars photos using this planet processing technique. Here is a screenshot of my computer desktop during practicing it. This technique is an idea I have had a couple of hours ago. It seems to work!
- Capture your planet as a video stream (avi file) in the allowed time window according to the resolution of your telescope+webcam combination, the planet (i.e. Mars) and its apparent size in the firmament. If you want to find out how long you can record the planet in a single avi file without to have a smearing effect caused by the planet rotation then run my free software "AstroDigital.Net". It computes it!
- Stack your avi file by using the GIOTTO software. The result is the automatically generated .FITS color file "resultcopy" in the same directory as your avi file.
- Sharp your resultcopy file by using the GIOTTO software. Save the result in a .FITS color file called "resultcopy_sharp_390.fits":
- Load the color file resultcopy_sharp_390.fits in MaximDL. Make a TriColor split to separate the three sharped channels R,G,B. Save them in your harddisk as:
- Duplicate the resultcopy_sharp_390-R.fits file as resultcopy_sharp_390-L.fits (L means Luminance, i.e. we will use the red channel as luminance) in the Windows Explorer window.
- Load the resultcopy.fits in MaximDL. Make a TriColor split to separate the three channels R,G,B. Save them in your harddisk as:
- Load the files resultcopy_sharp_390-L.fits , resultcopy_sharp_390-R.fits, resultcopy_sharp_390-G.fits, resultcopy_390-B.fits in CCDSoft.
- Adjust their histograms.
- Invoke "Color Combine" window.
