“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:The objective of the challenge is NOT to assemble a 60mm "best targets" list. Rather it is to push participants to try and find the limits of a 60mm telescope and, hopefully, come away with the sense that 60mm is larger and more competent than they expected or, if they cut their teeth with such a scope, more capable than they remembered .

Quote: Incidentally, I also looked at a few 60mm to 70mm currently available scopes that might be nice options. The Meade NG-60 runs about $80 and looks like a modernized iteration of the classic alt-az mounted beginner's 60mm achromat.A Vixen 70lf or Meade NG-70 or, stopped down a millimeter or two, also, might be an option as well.

Quote:In fact, I would even accept a well-constructed argument that a considerably larger catadioptric (such as a 90mm MCT) was inefficient enough to deliver actual light grasp on par with a much smaller unobstructed scope. If folks want to come up with a calculation of equivalent unobstructed light grasp for small catadioptrics, I'd have no objection.

Quote:I'm using Anatres model FOCR2s on my three Cartons. I don't know if Antares offers these any longer, but of they do, they're actually a very smooth R&P unit. I think I paid about $29 each for these focusers.

Quote:Fortunately, the crowd I observe with is aware of the Old Scope's history. They treat it with the respect a "vintage" telescope deserves.Hmmm... does a 1970 60mm refractor really qualify as "vintage?" Because if it does, well, I bought the thing for myself. Which would make me... Uh... Mature.
