But I have never owned a Brandon EP, yet. I am think about purchasing a single Brandon EP to see what this mystique is all about. My main scope is an outstanding 4" f/13 Carton objectified achro.

If you Brandonista's where in my shoes, which Brandon would you purchase if you could only purchase one?

Looks like you have a lot of nice eyepieces now. I'd probably try the 8mm first. 165X should be usable most any decent night on the planets.

I like the 16 and it barlows very well. Get the flat top version or take the rubber eyecup off, it constricts the view.

If the 50-degree field is OK, then whatever focal length you need right now. You really can't go wrong with any of them. I'd suggest the 6mm (my go-to planetary EP in my big SCT), but I see you already have a 7mm RGO.
The 48mm is just amazing; if you can use a 2" eyepiece, that's a must-have IMO. It's replaced my 31mm Nagler for the bulk of my low power viewing.

I'm with Rick; whichever FL best fits your current line up. They're all equally very nice!

I've got a 12mm Brandon that sits in my eyepiece case while I use Radian's instead. I haven't seen anything yet that the Brandon does that the 12mm Radian doesn't. The tone doesn't bother me in the least. The Radian is however, sharp to the edge in my f-6 scopes. The Brandon is not. I can't see any thing in the Brandon on axis that I don't also see in the Radian. I may sell the Brandon soon.

I'm sometimes tempted to get a Brandon (probably the 16mm) for the sake of diversity amid my otherwise all-widefield collection, but I'm not sure it will play well with my scopes, which are f/6.2, f/5.4 and f/4.9, all of which are manually driven...

For the OP's f/13 however, that wouldn't be much of a problem.

If (and only if, because I did not personally find the Brandons to be all that) you belive that the Brandon is going to be the best in it's focal length, then it would seem to me that the best focal length to get for your scope would be the one with a focal lenght that would be used for planets, where maximum contrast is highly desirable.

In your case, that would probably be the 8mm.

That way, if you belive that the Brandon is the best best best eyepiece ever ever ever, you would know that you are getting the absolute best planetary view your scope is capable of showing.

Also, the narrow AFOV of these eyepeieces is not an issue for planetary viewing.

Buy used. Saint Chester's Psalm #134: "It is not Sin to be Cheap."

My favorite is the 6mm. Then the 8mm. Then the 12mm. Then the 32mm. Then the 48mm. Then the 16mm. Then the 24mm.

The 24mm is the least "Brandonesque" of all Brandons. It has a larger AFOV than the rest and suffers off-axis astigmatism in faster systems.

I think the 12mm is the most Brandonish of all. Not too short, so as to avoid the whines and squawks about "too short eye relief", not too long as to be victim of the fussing and hand-wringing about excess eye relief and blackouts. It's the "Goldilocks" Brandon for first timers. It Barlows well, too.

Regards,

Jim

Uh, where'd he say he gave a "fig" about observing planets with it? A 4" long focus achromat does *everything* well. Let's not stereotype, what say.

Hmmm. The 24 has always been my favorite. Long eye relief, barlows well. With the Dakin 2.4 barlow it exceeds the performance of my 10 Delos. As much as I lve my 22 Panoptic, in many cases I actually prefer the Brandon due to the razor sharpness over most the field. (But at f/13 you may even due better.) Really, it just comes down to the size of the target. If the 24 Brandon can frame it, that is the eyepiece that gets the call.

You could go with a shorter Brandon, but you can't make it longer. If you only get one, the 24 does double duty.

Yes it is. With my Astro-Physics Star 12 (f/8.5) I use the 48 Brandon over the 31 Nagler. Not only are the views superb, but the 48 Brandon only weighs 11 ounces. Using the 31 Nagler requires a rebalance of the scope, otherwise it puts a lot of strain on the motors of my GM-8 mount.

You hit the nail on the head.

Though my fave, like yours, is the 6mm...can't imagine a planetary session without it as a benchmark.

But for somebody thinking "just one", the 12mm is obvious. As you say, a good first choice. :cool:

Cheers,

Jim

I did not presume that he wanted to view planets exclusively.

He asked what focal lenght he should get, and since many people consider planetary viewing to be the most demanding application, and so many people rave about how these eyepeices do on planets, that if he is going to spend $200 on an eyepeice, he might feel that this is where he would benefit most vs a good Plossl or Ortho.

Anyway, he asked for suggestions and I gave him one. I don't see how that would be different from someone else saying "Get the XXmm" or "Get the XXmm." Each has a use, so why would their opinions be better (or worse) than mine?

That was the reason for my selling my Brandons and sticking with my Radians.Just superb eyepieces for all tasks.The tone in mine is neutral, unlike the first set I had in 1990 which was rather warm.

Good idea Jim, I may use the money to get my Zambuto mirror refigured or maybe a new secondary from GSO, to replace my 1/30 wave Antares mirror. It can't be the Brandon, no way. Don't want any stinkin Lasik, a white cane maybe. :grin:

Then save yourself some money and when anyone asks, just tell them it's a case full of "Brandon's". Now, fill that case up with some decent "Brandon's"...

Thanks for all the replies, I will need to dig through this thread in detail before making any decisions. From my primary observing spot, the backyard, my main targets are double stars, followed by lunar, planetary and solar. I usually save deep sky observing for the occasional times I can get out to a dark sky spot.
