ROAST ::

Another Dwarf Mini session last night. I plugged in a power bank for an extended session, but I stupidly forgot to turn it on 😢 so halted things when the Mini’s battery was down to 25%, after about 3 hours. Doh.

Anyway, this is M13, the globular cluster in Hercules:

As always, click for a bigger version. M13 is a small satellite galaxy of our own, and contains perhaps half a milliion stars. Stars are packed about 100 times closer together than in our neighbourhood, so the night-time sky of a planet in the cluster must be spectacular.

Here I took 50 30-second shots with 5 failures, gain 60, Astro filter. Slight sharpening and saturation in PhotoDesk.

There’s a feature called the propeller in this cluster, which the Mini has managed to resolve — see right. It’s just a chance arrangement of dust lanes in the cluster and our viewpoint.

And below is another attempt at Bode’s Galaxy, M81:

This time I was more conservative with the settings, which has significantly improved the result. 200 images with no failures, 30 seconds each, gain 60 and Astro filter. No processing!
