Saturn in bad seeing with a QHY5L-IIC

Saturn in bad seeing with a QHY5L-IIC

After reading the post by Ray(Shiraz) http://www.iceinspace.com.au/forum/s...d.php?t=105057
and calculating the resultant F number for my F5 newt
and QHY5L-IIC combo (3.75 X 5 = F18.75) I bought a 4X powermate to give me F20 and set out to see what the result was like. Then the clouds moved in (mumble,mumble,mumble) and three weeks later they finally parted. On 9/05/2013 with the seeing best described as
"Whoa - settle down boy!" I decided to at least work out where my 10k step/cm DIY electronic focuser needed to be at F20 so set to work and also took a few videos.
Set the colour to "force GRBG" as suggested by U.K.Cowboy (Stuart)
(http://www.iceinspace.com.au/forum/s...d.php?t=106212)
and exposure to about 30ms (30fps) with gain at 45% as saturn wasn't very bright with a lot of high altitude misty stuff above Adelaide.
Here's where Autostakkert showed its stuff. Somehow it pulled a reasonable image (for me at least) of Saturn out of what would normally be considered complete rubbish.

Well done Emil!!

Now if I can get a night with great seeing I might be able to get an image like this.
