"... I am amazed at how stable the scope is for such a lightweight structure.
Vibrations damp very quickly after movement, and collimation holds effectively.
My only concern is that azimuth motion is slightly sticky with the additional
counterbalance. I may need to add some lubrication to the azimuth surface.
The optics are very good. I have had excellent images even in fairly bright
suburban skies. I look forward to taking it to a truly dark site. Coma is
minimal despite the fast focal ratio. I have not need to use a Paracorr yet.
Setup and takedown are becoming very easy now that I have had practice.
I must congratulate you on the brilliant design. My observing companions are going to
be very impressed when I show up at the next star party with this scope in the
backpack. Based only on some e-mail discussions, I have already been asked to
write a short article about it for the Minnesota Astronomical Society newsletter
Overall, I am very impressed with the instrument. You have done an excellent
job designing and building it.
