I wish we could have talked him into going forward with the 2" Brandon 36.

Thanks again to all who responded. It's clear from what I've seen here and elsewhere that it would be hard to go wrong with any of the Brandon line. I've ordered a 24mm flat top so I can see for myself.

{I wish we could have talked him into going forward with the 2" Brandon 36} ...............

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.

If you mean "was she the downpayment?" uhh, not really - I was trying to show that she was also willing (as well as I) to spend pretty big bucks for the eyepiece, not just a guy who says he wants it but when it comes time to pay up the wife says no!

The 4mm Chester Brandon built is the only Brandon I've used that really wasn't very good. The 24mm has a wider AFOV than the rest, but suffers badly for it off axis in anything faster than ~f/8 making the extra FOV kind of an irrelevancy. My faves are the 48mm, 8mm and 16mm. But I wouldn't trade any of them, save maybe the 4mm, for any other simple eyepiece, ZAO IIs included.

Regards,

Jim

Thanks Jim. I'll be working with the 24mm at ƒ10+. I expected this of the extended AFoV. I just have a niche for this FL at the moment and wanted to step into the Brandon experience. For future reference... any comments on the 12mm?

Edit: BTW, thanks for the heads up on the $60 refractor. I have "joined the club" and am duly impressed.

Great about the 102GT!

The 12mm is fine and very typical of the other Brandons, save for the 24mm which has wider AFOV than the others. Brandons Barlow extremely well, too, and just a little bit of Barlow amplification tames off axis astigmatism in faster scopes. So if you go 24mm, you can always Barlow to get 12mm and address any astigmatism to boot.

Regards,

Jim

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.

ES is now selling telecentric's at a much better price. They're getting great reviews on these forums. They call them "focal extenders" but they're the same as the Powermates.

Thanks Steve. I'm considering that as well. The nose seems long and I would prefer it to fit fully into a 1.25" diagonal. I'm not sure the Televue will either.

Love 'em all, but the 24 is my favorite. Views through it are immersive.

Three, maybe four more weeks of monsoon. Why can't it happen in December and January?

Then I'd have to shovel it. I'd be happy with one night or a decent sucker hole. This summer has been the worst in 5 years for observing. At any rate, I'm looking forward to the new Brandon. It looks to be a different experience.

I bought 24 eyecup and 16 flat top Brandons used mostly barlowed for lunar-planetary and HA. I'm very happy with them what with their excellent contrast, scatter control and sharpness. They are easy to use in and give great results with my barlow collection which is all the 1.25" TV barlows-Powermates and a Siebert 1.5X. I didn't get the shorter FLs partly because of their ER but mostly because the barlows give me those FLs. After getting a 5 XO a couple of weeks ago and finding it fairly easy to use during a 2.5 hr high humidity session I shall fear no ER! As to dewing-fogging up the Brandons aren't prone to it.
