JUPITER Sequence Mar 26 - with sps900nc webcam

Hi All, some pics of Jupiter and moons from this morning with the Mewlon 180 and sps900nc webcam.

The only thing I can say nice about the seeing this morning is that is was better than yesterday morning. I took a range of avis from 3.20 to 4.20am. The seeing started "ok" around 4-5/10 dropped to 3/10 and rose again to 4-5/10 toward the end, this can be seen in the image sharpness in the sequence. I could no doubt improve on some of these, but the quality doesn'y motivate to spend any more hours.

DP, I tried the 4x at the end, but power supply died after 10 frames

Again I was running Gain between 60-80%, Gamma 50% and Brightness 50%. Still a bit ONIONY, but not as bad as night before. K3CCD light meter hovered between 220 and 230 so no under-exposure. Oniony bits courtesy of seeing wobbles I reckon.

cheers,

Not bad Rob.

As you say, the seeing played a large part.

Nice to see Starry Night got the unfolding events spot-on.

Were these taken using the 2.5X Powermate? Any extension tube. Nice image scale. Did you re-sample?

Thanks Matt, yes these were taken with the 2.5x powermate on my 7inch Mewlon cassegrain. As it's an F12 this is around F30 (as opposed to F25 on the c9.25). No resampling, this is how it is

cheers mate,

DP the 4x didn't look any brighter (remember this was with the Mewlon so only 7 inches and at F48) but a tad less noisy.

cheers,
