On 21st of December I took my camera and all the stuff to the observatory site in Kiel Kronshagen. I had the chance of taking images through the 150mm (f=2250mm) of Hubert Paulus. Seeing was not best, but I hoped to take some "cool" shots.

So here is the result of this session.

Jupiter taken through a 150/2250mm refractor 21.12.2011


Jupiter in main focus. This is indeed my very first L-RGB image, where all colour and the luminance image were taken through appropriate filters. Image procesing was made with Avistack 2.0 and ImagesPlus 4.25.


Jupiter in main focus. Here is a single luminance image showing quite a lot of detail. Image processing solely with Registax v6.0


Jupiter in main focus. This is the same image as above but I tried the drizzling method. At the end I can not tell, if this one shows somewhat more detail than the originally sized above.


I did some more work on the RGB image. This is a composition of R-RGB, meaning the red channel is selected as luminance channel as well. The upper image shows as it is with the violet tones; in the lower one I changed the violet against yellow and brown, making it look more "natural". But this is NOT the way it should be done.


Again a rework of the image with R-RGB composition.


Here are more treatments of the R channel. I compared Registax6 and ImagesPlus4.25 in sharpening/denoising. The images were stacked this time with Autostakkert V2, which just came out these days (Feb 2012). Best of all - my findings - seems to be a VanCittert deconvolution with additional weak Wavelet smoothing. Registax ist not bad either.

Jupiter from Rainer Anton 21.11.2011


This Jupter image was taken by astro-colleague Rainer Anton through his newtonian scope and a TeleVue barlow lens. This is a single raw image !


Here is the processed image showing a lot of detail. I used Avistack for stacking and Registax for final processing.
