Dave, thank YOU for always engaging me. I'm honored just to scrimmage with you. I'm Yesterday, someone too long removed from the academic side of astronomy to be sharp enough to really stay on top of it. I tell folks now that my hardware is "cutting edge" - for 1977! Same with the bulk of my 'knowledge' Im afraid. But it's kind of you to dance I must say. I still have my first "real" star atlas, epoch 1950! And when I got it, it was still closer to 1950 than 2000 and the only real thing in town besides Nortons that I knew of. (Yes, the rumors are true, I have a laminated Skalnate Pleso, laminated myself on the Granite District laminator decades ago, and I believe to be the FIRST laminated atlas EVER...). I'm just a Working Joe with a family and a mortgage and never enough time to relax at the eyepiece anymore. You are Today, and far more knowledgable than I. You and the other enthusiastic, energetic observers on this list. I love the observing reports, it sure takes me back to a galaxy long ago. Keep up the analyzing!
