First light of my new RASA 8 scope. There was only a brief 2 hour clear period last night and I managed to get 60 mins of HA which I've integrated into an image taken with the Esprit 80. The HA for 1 hour with the RASA has more nebulosity than 10 hours on the Esprit (though the Esprit data had lower gain settings so not best comparison). Ideally this needs far more RGB and HA for better image quality but could not resist a quick first experiment with new kit.
