During the first nights my QSI 632 with the 200mm Canon-lens rode piggyback on the refractor. But this proved way too complicated (second laptop, framing and focusing were tedious). Too many frames came out either unsharp or elongated. In addition the brighter stars showed the ugly blooming of the Kodak 3200 chip; as a consequence the Canon 6D got the 200mm lens and was mounted piggyback instead.
All the L-frames were left out, as they were not properly focused. Despite these problems and the suboptimal framing it is quite a pretty picture.
