Saturn back on 11/13/2002

Since the weather in Indiana has only cooperated once since the end of October, I thought I'd post this last vestage of good seeing in Indiana from back on 11-13-2002.

This Saturn image was at 6:30 am using a Philips Vesta Pro 690K and a Televue 2.5X Powermate attached to a 12.5" Portaball. Tracking was achieved with a Tom O. single axis platform. Recorded an avi file at full 640X480, 30 fps, 1/33-second exposure, and manual gain of around 70-80% for a total of 1041 frames. Picture is the result of the 492 best frames picked using Avi2Bmp, stacked and processed with dyadic filter in Registax. It was necessary to make four individual stacks; three of 120 frames and one of 132 frames. Each stack then required boosting color saturation in Adobe prior to final stacking in Registax. For some reason, Registax partially negated the color even when color processing mode was used; thus, boosting the color in photoshop on the individual stacks was required. Final processing in Adobe Photoshop 5.0 LE still required more color saturation and a pinch of Gaussian blur to quench graininess from Registax. Sky stability was pretty good for Indiana in order to use this high of a percentage of frames; normally can only use about 20%.
