Well finally the clouds cleared for around 3 hrs!

Here are some rough pics, all not focused correctly to boot.

The 1st is a clip from Ptolemy Cluster. I definitely didn't get the focus right. I just focused on live view...didn't zoom in for focus. Anyway it shows quite a bit of purple flaring. I suspect this is just focusing though as the below results were better.

The 2nd is a clip from M20. I refocused using live view zoom then slewed to M20. I should have tried re-focus at the target! There is substantially less flare but the stars are un-focused! Sigh!

The last is just 4 x 180s exposures of M20 (ISO400)...then in came the clouds. DSS stacking didn't like the un-focused stars and has left some artefact's on the image of them.. somewhat.

There is some field curvature...all in the same direction. Maybe some focuser droop or camera not square?

So ATM I need to do some more pretty pics to really test this out before judging. I like the light gathering of the 5" though!

Edit:

Forgot to say...it was awfully cold and the M20 unfocused stars do look a bit like dew. It's a possibility.
