My first attempt at guiding using PHD2. 10x3min lights and 3x3min darks at ISO 800.  127mm. Meade 500 series refractor, Altair astro field flattener and x0.8 reducer, imaging camera-unmodded Canon 600d DSLR and QHY-11 colour guide camera. A bit of post capture fiddling with DSS,FITS work4 and APS. Pleased to capture one of the two 4th mag companions within the glare from Alnitak . I also think you can see a bit of the shadow from the Horsehead (below it and to its left) - probably wishful thinking!
