Another test of the 0.8x TS corrector on the C11 with modded Canon 550D with IDAS LPS-D1 light pollution filter.

The wind was buffeting the scope quite badly so the guiding errors were around 1.5 arcsec RMS at best.  I've stacked the best 8 subs out of 29 - each was 5 minutes long.  I didn't take any flats.  The collimation is slightly out at the bottom right but otherwise all is looking good for the next clear night.
