Best resolution with new camera

The skies cleared for a short while on saturday evening, so I took the opportunity to do some timelapse filming. Unfortunately, as per usual, some clouds/fog ran in front of the planet. So the guiding failed, and Jupiter slipped out of view. But I did get about 1.5 hours worth of videos. I did the usual processing. But this time I also added another step. I found out that Gimp actually has a batch-mode! So I could do some sharpening there, and when I knew how to sharpen a single image, I just went ahead and did it with all of them. There is still some noise in the images, so I need to figure out how to make them less so. But I am getting there...

Tech det : 200mm Klevtsov-Cass w/2.5x Powermate, recorded with SharpCap. ASI678MC binning 2, gain 300 6.25mS exposures. 20 seconds of exposures with 40 seconds intervals. Stacked in AS!3, wavelets/whitebalance in Registax, extra sharpening in Gimp and animation in PIPP.

Jupiter October 11th

 Yesterday night was clear'ish. At least for most of the night. I started recording 4 hours of videos from around 11.30PM and went to bed. In the morning, I closed down shop and went to work. This evening, much to my disappointment, I found that most of the night was miss, since obviously a could had moved in front of Jupiter, making the autoguiding fail. And thus I only got 47 videos in total. But I DID get the Giant Red Spot! I loved it. So here is the short animation. This was also with a new camera, and without the Powermate I had used previously. There was a lot of turbulence, so the images didn't come out superclear, but I am happy with the result. Looking forward to the next really clear and steady night.
