Tell me Rick, how many bias did you collect to use the super drizzle ?
Best Regards and congratulations for the outstanding result,

Thanks, Fernando!

I didn't do anything special with the bias frames and can't remember how many I used to build the master for that camera. It was probably around 100.

For drizzle I think the important things are to have a decent number of subs, well-behaved dithering and good SNR.

Superb colour balance, reminds me of NGC 6559 in Sagittarius.

Cheers,

Thanks, Justin. Yes, it does have a similar mix of features. I should go back and re-do my last NGC 6559. I struggled with the colour on that one. Perhaps I have learnt a few new tricks in the meantime

Thanks, Kevin! There's no magic to it... at least not that I've found. Just a matter of incremental learning and improvement. Keep at it and you could be running rings around me before long.

Not likely. I'm too old and senile now.

Some of the young engineers at work would claim the same about me
