Very cool!

How does the Umi17 perform with the 200PDS?

It performs very well, handling winds up to 2 m/s without any issues on a standard CG-4 tripod. RMS is consistently below 0.8", which is just slightly below the upper guiding limit for this focal length and camera combination. However, I use a corrector from Quattro, which gives an actual focal length of 865 mm instead of 1000.
