Nice resolution.

Nice resolution Jorge. Colour is not quite right as the cluster has mainly old red giants. Your black point appears to be clipped too and that would be hiding fainter stars.

My suggestion is for you to try some of Ken Crawfords tutorials.

well told and well remembered, Paul. I will review the original, it might be by the digital treatment.

Can you post the link to Ken Crawfords tutorials ?

A week with a thin rain. Suddenly, a good seeing. But only two hours. After time lost with installation, I only got a single 10 sec iso 1800 shot before the rain fall again.
Despite of it, I got a more colored image.

Thanks Paul for Ken Crawfords tutorials link.
