M13 on a night with almost a full moon
« on: 10:13:34, 14 May, 2017 »
Inspired by Darth Muppet I thought that M13 might be an object that could still be captured despite an almost full moon.

Stars a little elliptical so an issue to resolve on the next clear night.

14x300s light frames.

Perhaps a tad of perfect focus (which is all so important on clusters) but nice nevertheless.

Yes, I think so Chris.  I think the autoguider may have been off focus too, or guiding on a faint double star, causing the elliptical star shapes.

Hopefully get it right next time.

Looking good though otherwise, just needs tioghtening up and also imaging something like this with a full moon was always going to be a challenge so overall you done superb.  Is it auto or manual focus you are doing Dean?

It was autofocus, but rather silly of me I defocused to check collimation and then returned the focus to the previous position rather than running another autofocus.  At the time I thought that was being a little too optimistic!

I use SGP for the autofocus routine.

There is actually more data there than you realise Dean, just a 10 min tweak on Photoshop...
