Bit of an experiment with the RASA and Esprit 80. Skies kind of finally cleared here in the UK but moon very prominent. This is 1 hour HA and 30 mins SII on the RASA with about an hour each of R, G and B on the Esprit for the stars. Exposure times purely weather limited. Colour in stars isn't quite what I was hoping for, I think the moon is just too bright at the moment for RGB. Didn't even attempt OIII as SII was pretty washed out. I do quite like the skull shape in this image. No flats.
