Jupiter revisited (again), and some new technology
I lashed out on a new ‘planetary’ camera, a ZWO ASI224MC USB3.0 Colour CMOS Camera. It’s a jumped-up webcam really but a bit specialised for astrophotography. It’s going to take time learning how to use it well, but first experiments look quite promising. Also, it’s a lovely colour.
Planetary imaging from Glasgow in March 2016 means Jupiter and the sky cleared last night for my first attempt with the new camera, from the back garden. Stellarium showed what I might aspire to as usual:
Here is an image stacked from 500 frames of a ‘movie’ sequence – although the equatorial mount was doing its best to prevent Jupiter moving out off shot.

High Speed Mode=Off
Frame Rate Limit=Maximum
The camera comes with a 2.1mm CCTV lens, and a regular tripod fitting screw – which means it can be used without a telescope to take ultra wide-angle ‘all-sky’ shots! I had a go with that after I packed up the ‘scope but before I moved the tripod, so the mount was still polar aligned and could track the stars at the sidereal rate.
The 2.1mm CCTV lens does have quite a wide field of view, which might surprise the unwary:
