Quote:I'm generally aware of the characteristics of the Brandon design and its execution by Vernonscope but wonder if any are particularly good. I'm considering a 24mm flat top at the moment but that could change. Thanks for your input.
Quote:hmm.. Ilke the all. I have the quad turret and can only fit 4 out of 5 of the 1.5 inch ones. So I have the other probem; which am I willing to do without... often it's the 24 so I can get the 32 in for widest field. interesting, maybe I need to mix it up more.
Quote:Thanks all. This is helpful input. Would the 24mm play well with a conventional Barlow (TV 2x) or would you recommend the Powermate (or 2.4x Klee)? I'm working on building a "simple set", perhaps 2 EPs and a Barlow. My experience with longer FLs and Barlows has not been very good.

It's funny how one learns to live with it given some time and effort.
Quote:Of course, I still prefer longer - but I will no longer allow a reputation for short eye relief to automatically rule out an eyepiece.

When I last saw Don I must have spent 25 - 30 minutes just talking about producing the 2 inch Brandon 36mm. He wouldn't even take a down payment - even with my wife next to me. It basically came down to how long would he have to sell 100 pieces and not tie up his money for a long period of time.
“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.

Quote:That's good news about the Barlow. As I mentioned earlier I'm building a "simple set" that could include a Barlow. I've just had bad experiences with the exit pupil moving around with long FL EPs. I'll give it a try. I have yet to spring for a Powermate.
