I'm using a Losmandy G11 with a Orion Starshoot Autoguider and PHD guiding software.
Also I used a Baader MPCC coma corrector and a IDAS LPS filter. I have had trouble getting the spacing correct on the MPCC. The company says it should be 55mm from the camera chip but when I space it at 55mm the coma is still around the outside of the field. I tried 50mm and it was worse and then I tried 60mm and the coma dissapeared. This shot was taken before I found the correct spacing.
