I've also got the 224 and the 290 (and the 1600MM cool). I previously did some tests with the 294 on the moon and I was very impressed with how well it performed. The large chip comes in handy for locating the field, and then I switch to ROI to kick up the frame rate. Tracking was excellent during these runs.
I almost forgot...
These just happened to be the very first sequences that I grabbed intending only to use them as test images. Somehow I got lucky. As soon as I grabbed these two sets I had a few minutes before Jupiter reached the meridian (I can only image on the east side of the meridian from my hose) so I went back and turned the gain up to 300 and turned the exposure down to 25ms on Jupiter and 50ms on Saturn. I also grabbed 5-minute and 10-minute sequences of Saturn. I stacked 10%, 25%, 50%, and 75%. None of these were sharper than the first set that I show here. The problem; in 10 minutes the seeing went from fair to something less than fair. The shorter stacks sometimes look sharper than the longer stacks, but its an illusion as these stacks tend to have a higher degree of high frequency noise. If I blink the images, the longer stacks actually show more fine detail and less noise, though the overall image may look a tad softer because of the lower high frequency noise. Just for yucks I might spend some time looking at the FFTs for some of these data sets. Regardless, the final results are soooo much just the luck of the draw as to what seeing is going to give us.
The Plan moving forward is to spend some time zeroing in the collimation, sneak the gain up, the exposure down, increase the number of subs, and re-learn how to use WinJuPos (it has been a while). Heh, heh, some of the best planetary imaging that I have ever done was using my SC8 at f/30 using my trusty old DBK21. Of course the ecliptic was a _lot_ higher back then. I'm love'n this C11 and the ASI294MC and I'm gonna stick with'm all the way through Mars season. Surely I can do better with this gear than my old LXD75 SC8 & DBK21!
One night at a time...
Have fun folks!
