The Heart Nebula (IC 1805)
Observing location
Stanmore, Greater London (Bortle 8)
William Optics RedCat51

ZWO narrowband filters
30 x 300s Ha, 40 x 180s OIII, 24 x 300s SII, Gain 200, Size 2.96 x 3.81 deg

Shot over two nights this was the first major test of the ZWO EAF (electronic auto focus) on my WO RedCat51.  Very plug and play and whilst I initially verified focus with the Bahtinov mask I'm now confident I can trust the EAF to set the focus and adjust between filters automatically.
