That's a shame, Steve. I've always used CCD cameras and tried some DSLR wide field stuff recently but really wasn't happy with the pink stars and other issues. It was possible to make a nice image but a lot of effort went into fixing the deficiencies in the data. So, I decided to limit the DSLR to daytime landscapes and bought a couple of cheapish ZWO CMOS cameras...
Cheers,
Rick.
