Here is the picture, if you want details ask.
Canon 5DH, Canon 300mm F2.8L at F2.8. Hutech LPR filter, 14X360sec ISO 400, processed with ImagesPlus, RegiStar and GradientXterminator. Combined odd and even frames as median in Registar. 2x(7X360) then summed these two frames. This is then the equivalent of 7x720 sec.

Beautiful shot Bert!!!! love that 300mm lense,
Only little niggle is the dark neb seems a bit on the red side?
Other than that, a awesome image Bert..
Cheers Gary
Many thanks Bert got the file. I was wanting to see an unprocessed image to see just how fine the non-IS 300 2.8 lens is, no wonder they are still attracting 3-4 K Aus secondhand.
Did you convert the raw to tiff or fits without any sharpening etc? By the way the 300mm F2.8 Fluorite that tornado33 has got is the earlier version of the 300mm F2.8L. The only difference is the later version has two ED elements as well as the Fluorite as ED glass was not around then. Optically the earlier lens has got slightly more off axis astigmatism wide open. It would not be as good for full frame but still nothing else would come close. The real advantage of the the earlier lens is it can easily be used with an Astro CCD as it is fully manual.
Keep an eye out for the arriflex version (very rare) as it can be easily converted to fit an EOS mount with focus at infinity. The FD mount version may be converted to fit an Astro CCD but not an EOS mount without an extra glass element to get focus at infinity which ruins the quality.
colour aside there is so much detail within that shot it is so hard to describe - unfathomable
