Got a nice day today with average seeing so setup the LS80 and was able to get a relatively crisp disc thru a 10mm Delos with proms between 3 and 5 oclock on the disc. For grins I switched to a 6mm Delos and no matter what I tried I couldn't even get close to focus. I moved the B18 in and out a bunch of times, no joy. All I got was a tiny blurry almost airy disc.
Any help please?
