Hello Dexter,
wow amazing picture! ... detail, no noise, saturation: everything perfect ;-).
The only thing that would improve perhaps a bit 'is the white balance, but as always the colors are subjective so feel free to discard this observation. A "my" version would be this:



Hello and proxima,
David

David and Zipablo thanks guys :-)

David very balanced your version :-) being still the first trials I try to "find" by images of catalog information on how to set color profiles to return a more "realistic" as possible ... even if it is within the stellar really a business:-D thanks again to you ;-)

compliments, the picture is well done, I see no distortions in defects of another type. Noise absent.
Exaggerated the nitidezzawow!, You used an unsharp mask much boost?

Fabercom thanks :-) I pushed pretty indeed:-D especially in the area of ??the nebula but it seemed to still remain within acceptable limits :-)

Very beautiful! It 's very contrasted, but have not come out too obvious artifacts. For white balance I would be in your and that of David, with a slight preference for one of David (a little too cold for my taste, but a little 'more balanced in your version).

hello

Clare

Very nice, but I still have not figured out how to work the shot? The synguider CCD is used to locate what you need to photograph, or to connect a camera? The camera is mounted at the prime focus or above the telescope? They are very fast in this area, but I'd figure it out as I already said in another photo if you want to also thank you by mp.

Mysa hello, thanks for the ride :-)

then: the Synguider is a guide camera "stand-alone" in the sense that it does not need to be connected to a PC for set-up. simply connect it to the frame, locate a star bright enough in the vicinity of what you're going to continue (the display has a very spartan but that allows you to see in real time the stars of a certain magnitude), then use the lock-on function and room guide and correct the errors of the micro-movement of the frame :-)

the camera is connected to the telescope (a Newton in my case) to direct fire via an adapter and with the coma corrector to eliminate the distortion at the edges :-) telescope in practice becomes a mega-telephoto focal length equal to that of the tube :-)

also ask for anything anyway ;-)
