M13 in Hercules

Hazy sky last night so I setup the 250pds ready for when we eventually get a clear night. Amazingly skies must have cleared at some point as it managed 88 mins of data. SkyWatcher 250-PDS with 1600MM Pro - in just 1 and a half hours from Bortle 5.

Thanks. Was pretty surprised with it as expected absolutely nothing given poor conditions. Need to figure out how to fix the stars though.

That’s a great image! I love the star concentration and colours- beautifully presented. Nice galaxy top left too!! I have SW200P and I get some asymmetrical flare with star diffraction spikes too if that was what you were referring to?

Thanks. Yes, the cause has just been explained on astrobin (thanks Minos) - its the mirror clips and can be fixed with an aperture mask.
