One of the faintest nebulas to catch..the squid nebela.
Even with a Fast 10 inch newton i could almost see nothing on a single sub from 900 seconds.

But whe are lucky here in the netherlands with a heatwave and very dry clear nights..the moon is gone,so i gived it a decent try.
Im happy or now,but the nebula is so big,it need a wider FOV scope,600mm would be perfect i think.
