Description

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!
