Jupiter 2015Feb28


This was the first clear night where the temperatures were not colder than -20C with a stiff wind. Even so it was about -15 with a little breeze early Saturday evening.
The moon was 10 days old and within 26 degrees of Jupiter, so the sky was quite lit up.
This was using the 10cm Meade SC telescope, tracking in RA, FL=1000mm, with the ZWO ASI120MC camera, firecapture and autostakkert to process.

The seeing was not good and in the raw video one could make out almost nothing of the surface features.
821 frames in total, the best 50% used to stack to create the image, 60 seconds of exposing at 4.8ms each.

The second image is with a celestron x2 barlow (fl=2000mm). It was much harder to focus and the image is much software, lower contrast, lower brightness and lower resolution than the first. But it is x2-3 more pixels, with potential in the future to do much better.

The images have been flipped so north is up and follow the rotation of Jupiter from left to right.
The raw video has 3760 frames, of which 50% were used to stack, each exposure was 16ms.
