Out of the blue there was a clear night 2 days ago. Here also SO much clouds the last few months, so it was a rare sight
Also took a set of captures of M13. Somehow I do a short session of M13 each year.
So this is data from 2021, 2022 and 2023. Not much, just a bit over 2 hours.
30sec exposures for the core, 180sec exposures for the outer parts: the core is not overblown now while at the same time the outer parts have a lot of stars.

A decent globular cluster - stars defined in the centre and colours in the outer stars. A good return on 2h of capture.

Thanks Dave.
This is one of those case wondering what more integration time will bring

That is an excellent image Menno. Well resolved with good colour as well as deep.
