An old favourite, the M13 globular cluster. This is just over an hour of data taken before dawn.

Sony A7S on Celestron C11 with Starizona 0.72x reducer/flattener. Sub exposures were 30sec at ISO 10000.
Here it is at full scale: http://www.markshelley.co.uk/Astronomy/2020/M13_20200425.jpg

Very nice Mark. I like the excellent resolution right to the centre and the star colours are great as ever. I have a similar amount of data for mine but I still need the last colour - it's certainly easier to collect RGB in each sub !
Robert
Agree with Roberts comments, lovely as always.
It must be lovely to take such short subs and have dark skies.
Carole
Agreed with Carole , beautiful, it had reminded me i had DSLR and Hargb data of M13 from ages ago so will have ago but obviously not up to this standard,
