I recently acquired a 10" F4 newtonian which has been through the hands of several of my friends. After a couple of weeks buying equipment and teaching myself to properly collimate a fast newtonian I was lucky to get two nights in a row of clear sky around the new moon. The first night was going to be a little windy so I mounted my SVX80T refractor rather than a great big newtonian, but last night was clear and still, so it was testing time.
The image of the Sombrero galaxy is the best 55 out of about 65 X 300 second subs, chosen subjectively based on throwing out any subs with out of round stars, and then some more based on those where the star HFD was the largest, indicating poorer seeing. I wanted to keep to prime imaging time where the Sombrero was above 45 degrees elevation so I generated a script which shot the Sombrero until it went below 45 degrees, then changed to the Trifid nebula, on which I got 18 good subs, seeing had deteriorated a little by then as well. Via the script, Voyager seamlessly managed the two targets, and between the two of them, effectively three meridian flips (Once while shooting the Sombrero, back to the east to go to the Trifid, then one more when the Trifid passed the meridian) and then shot dawn sky flats before parking and warming.
