Most need a focal reducer to get in things like M42 and M45. I could do with a 6.3 for my LX90

Thanks Jennifer, yes, DSO's probably OK. But the moon too big. If one has a Canon or Nikon FULL FRAME DSLR the moon would almost certainly have been ok in the frame. Focal length of my scope is 1500mm so compared to a 35mm standard 50mm camera lens this is simply a 1500 telephoto, or more correclty a Long Focus lens, giving the
equivalent of 30 times magnification which is half of that of my 25mm EP. If I used my 2x Barlow only a small portion would be visible. Yes, you are correct, a reducer would be good, but which is best for a Celestron 6SE?
Might try that, but I do have a longer extension tube which will give a much enlarged image. Also when off (working nights til Fri) I will try some EP projection pics.
All this for beginner is quite exciting.
