First test with my freshly modified 6D (Baader-filter), the new Skywatcher 100/550mm triplett and 0,79x reducer. The 0,79x flattener does surprisingly well with full frame once the correct spacing has been found. 18x6min with ISO400 were used, I lost a few frames because some problems during dithering ocurred. However, Kudos to the EQ6 AZ, also the unguided frames had pinpoint stars despite 6min exposures, which I find quite remarkable at that f.l.

Thanks. Given that this was shot from my backyard, it turned out quite acceptable. From my dark sky side I could use triple exposure time to get the histogram to where it is in this picture, but the corrector was only on loan.
Brent, you have some experiance with camera modifications: My modified 6D with baader BCF shows ugly red halos due to unblocked IR. I know that the filter has a transmission window beyond 1000nm, but this was said not to be a problem because the cmos isn't sensitive in far IR. Did you encounter similar problems?
