The WO RedCat51 arrived quickly from FLO, as usual, and was well packaged. The scope itself looks fantastic and looks and feels a quality item. Iíve had one chance to use it on my EQ6-Pro (overkill, I know), and I love the scope already. The focussed is smooth and holds focus really well, and the Bahtinov mask built into the dew shield is inspired. It was a full moon so there were awful gradients in my M31 image, but the stars looked good all the way out to the edge of the frame of my Canon 100D. Plate solving is a breeze with the roughly 5x3 degree field, and guiding is a doddle (my guide scope has about the same FL as the RedCat51!. Iím looking forward to some darker nights (and the arrival of an Optolong L-enHance filter) to see what itís really capable of.
