I shot this a month ago today but just got around to posting it now. I used a f/6 focal reducer when I took this picture. The focal reducer didn’t work very well on other DSO’s as it left a nasty vignetting problem on the pictures. Its an ok accessory for when you want to have a wider field of view, but I don’t think its very good for imaging. It did work out pretty well for the moon though, without it I can’t get the full moon into the frame due to the high powered zoom. The adapter basically reduces the zoom by 40%.
