I have acquired this during new moon in September with my RASA 11" and just freshly bought ASI `294C OSC camera. My garden observatory is at the bnorders of big city, but it was OK and dark enough. I wanted badly to make this one a photo earlier, but could not manage to calibrate my lights. After over a month I reapproached it and .. here it is. Despite the colors are maybe not at where they should be, but it was really out of my reach to get more out of it. ASI 294C is a nice camera, but super strange and tricky for lights calibration. I have yet another 50 hours from this camera waiting for processing that failed at first try. Any comments welcome as usually !
