Mizar, Alcor, and PGC 3807486 with a 114mm scope

Another experiment to see how low I could go, this time with a 114mm newt. Once again I caught PGC 3807486 (18.55 mag galaxy), but it took longer subs and the result was even fainter than with the 6", so I may be reaching the limits of my aperture/skies.

 

In all fairness, it was also a somewhat better night with better transparency. Still, not a bad performance by the little newt that started life as an Orion Starblast, a scope that you can check out from some public libraries.
