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?
