The clouds have had us completely covered for almost over 2 months, but we did get Sven's D20 out to get some pictures of it, even if there were no stars to shine upon it.
As you can see, we trimmed a few inches off the Mirrorbox/ Rockerbox dimensions and managed to install even larger ALT bearings in the same footprint. Larger ALT bearings lets the scope balance through a larger range of eyepieces without resorting to counterweights.
The D20 is also available in f/5.
