Clear Aperture?
I hope this discussion has not come and gone, but if so, humor me. I
notice that Orion is now selling a 91mm clear aperture newtonian for around $900.00. Is anyone else offering any of these? Are they being used yet by professional observers? Anyone have some info on this? Thank you. Bill.
