Not bad for a standard tripod! Explains the slight trailing.
Thanks Gem,
I didn't realise that bias frames were so simple I will be doing them now. I appreciate the comments

I think, both might be due to too much highlight effect in the post processing.

and more darks and of course flats will greatly enhance the quality and make post processing easier, too.

I like your step-by-step-improvement approach and posting it here on IIS.
I benefit from your threads, too!
I noticed the exploding pixels too wasn't sure what caused it thanks for the info. Thanks for the feedback.
