About this image

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.
