Two Twofers (two fors)

After diagnosing a problem with the Declination “transmission” in the scope, and subsequently deciding to do nothing about it, I tried some more imaging. I also found a potential problem with the Right Ascension as well, and that may lead to a disassembly and greasing of the part of the drive. We'll see.
At any rate, I tried imaging a “bright nebula” in the constellation of Vulpecula known as NGC6820. Some of these nebulas (or nebulae, if you will) have nicknames (ie, M17 aka the Omega Nebula, and 3 others as well) 6820 has none. It's a twofer because there is an associated open cluster, NGC6823; image one and you get both.


NGC6820 and NGC6823 (basically dead center)

NGC6820 is an emission nebula; hence, the predominately red color, and it lies about 6000 light years away.

The other twofer is two images of Saturn which shows the increased value of more frames (images).


Saturn, 200 frames

This image has only 200 frames (the images are taken as a movie and the the frames processed as though each frame is an individual picture), the best 75% were processed and used for this image.


Saturn, 2000 frames

This image used 2000 frames and the same processing. I think shows more detail and is clearer. What do you think?
