After five nights in a row of good weather and deep sky imaging, yesterday was a bit cloudy and I was very tired smile.gif So, right after sunset, I decided to go for the Moon and then close everything. 

 

The image was taken with the IR-pass filter at 685nm as luminance and RGB filters for color. Processed with Autostakkert, Astraimage, Pixinsight and Photoshop. I might have exaggerated with the deconvolution but I couldn't zoom on the small details while doing so it was very hard to spot artifacts. Luckily enough only a few small brightest craters seem to be affected. 

The telescope used is a 6'' GSO f/4 newtonian (600mm focal lenght) and the camera an ASI1600MM-Cool, everything on a CGEM-DX Mount.

Thanks for looking, 

 

Clear Skies,

Oh My GOD, 3-4 nights ago i was using my new telescope for the first time ever which is 6" F/4 from GSO as well, and i was testing it with 4 cameras, 3 as planetary cameras and one as a cooled mono camera which i kept it and continued to image a DSO target too.

 

My Newt isn't collimated perfectly, when i put it first and tried to take any image of the moon it was completely bad, i thought it is either the seeing or filter or the scope itself, but i collimated it very quick anything badly desperately and WOW, what a difference, still not perfect but it gave results that it should be, i hope to make the collimation more precise and perfect to get the best quality of results.

Very nice colors, Andrea!

 

You can reduce the clipping from the deconvolution by simply reducing the white point by 10 to 20 (of 255) before you run it. In Photoshop, it's the right output value in Levels.

 

Cheers,

Did you use any coma corrector here?

 

I used my QHY163M camera with same telescope, the view of the moon is small, so did you crop heavily?

Yes the GPU 4 elements. I did crop some to gain fps since a good part of the frame was empty.

Got it, thank you very much
