This image is a result of taking 15 shots at ISO 1600 for 180 seconds. Sometimes you have to have luck as my declination motor gear slipped and was not performing well. Then the wind started picking up and gusts of 40 mph occurred. To top that off I kicked off the battery cable to my mount and when I reconnected I forgot to reframe my camera and so I lost 20 shots. Thus I had to make do with the 15 shots. I wasn't sure what to expect since my guiding wasn't great and my guide star was doing all sorts of scintillation and I about tossed in the towel. However, I was able to come up with a stacked image via DSS which was then mildly processed in Photoshop. I used a Takahashi FSQ-130ED and the 645 reducer for a focal length of 455 mm. I guided with a 60mm guide scope operating at 500 mm and a ZWO camera. I used PHD2 guiding software in combination with APT software and also dithered. Also, I used Spike-A-Flat to get my flat frames and flat frames do indeed help. I recently started taking flat frames. My imaging camera is a Canon Ra.
