On the morning of 13th April, I rose early to see how clear the skies were. Limiting visual magnitude suggested transparency was not great, plus there were threatening clouds on the horizon.

I almost went back to bed ... until I realised that scintillation of the stars was bordering on non-existent.

So I persevered, in the hope that the steadiness of the atmosphere would counter the transparency somewhat.

This image was created by de-rotating six separate 90s captures in WinJUPOS**, with a total of approx. 11,500 frames of data.

**My thanks to Niall MacNeill (AstroBin) and Darryl Milika (Cloudy Nights) for their excellent advice on getting started with WinJUPOS!

Wider field with Ganymede and Io in frame, which helped enormously with alignment in WinJUPOS - thanks Niall for the tip!
