I use Brandons with a 3x barlow. They do barlow very well, and with the 24, 16 and 12 I have plenty of eye relief. Suggest a driven mount only, as the target needs to stay centered. If you have a 2x barlow then I would get the 16mm. As others have stated, with your 4" refractor the 8mm makes the most sense.

I'm down to either the 16mm or 24mm. I will likely go with the 24mm and barlow for shorter f/l's.

I ended up deciding to start with the 16mm Brandon, and just placed an order with Astronomics.

I have a 16 Brandon now for about 25 yrs. now. It was my first good EP I bought for my C8 back then. Been banged around and even dropped but still working fine. Extreme light and very good contrast. A lot of nights I'm not able to go much higher in power because of poor seeing.

I do use it with my 2.5x Powermate in my 80mm scope and it works great.

Have fun with it

Hi Jim,

Which barlow do you like using with your Brandon's?

Peter

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

Pete:

I like the matched 2.4x Dakin, but also the Orion 2x Deluxe (full length, made in Japan) Barlow with them. Also, the Takahashi 2x Barlow isn't bad. I do not like the 2.8x Klee Barlow or the 2x Celestron Ultima Barlow as well as the others. The Klee seems to darken the edges of the 24mm and the Ultima seems to produce more magnification than it's 2x putative amplification suggests (it's closer to the Dakin at 2.4x in image scale than the 2x Orion or Takahashi).

Regards,

Jim

Hi!

I'll look forward to your reports after you start seeing through your new Brandon 16.

I suspect you will see for yourself what we others think is the "big deal".

Jim,

A 4" long focus achromat does *everything* well. Let's not stereotype, what say.


Yes, let's not. I recently sold a 4" f/10 achromat. Not quite an f/13, but I can tell you from experience, it did not do *everything* well.

Hi Brandon,
I bit the same hook! I had been reading about Brandons on this forum, but never saw any "used"ones for sale. So I did the same thing. My 16 mm Brandon arrived in Brandon, MS last week to use in my C8 SCT. I'm just waiting for a good night!

Jim, how well does the 16, 24 and 32mm do with the Dakin 2.4(and other barlows)? Do they push the ER out so far that eye placement is critical?

Btw, check out my CSC below for tomorrow. Looks like I will have at least one night with my 16mm namesake. For now I will have to work the massive x2 2" powermate and a cheapie x2 1.25" Celstron barlow that came with my bonus EP/Filter kit that that was part of the Nexstar 8 SE package.

I have to admit that I have high hopes that the Brandon is all that (some of you) guys say it is and knocks my (new artic) wool socks off, or at least makes them drop to the ankles. If so, I will be left with no choice than to complete the collection and perhaps sell off my BGO set.

Or not. :cool:

Having too much ER is rarely a Brandon problem. Rather it's the converse. The "down in a well" eyecup design coupled with a prescription that yields Plossl-like or tighter eye relief means that the 1.25" Brandons barlow without issue. The 32mm, perhaps, starts to get a little long with the Dakin, but honestly not as bad as something like a 35mm Celesrton Ultima without a Barlow.

The 48mm Brandon, though, has what I would call "excess" eye relief. It's a lovely eyepiece, but eye placement is trickier than on any of the others.

What scope will you be using?

Regards,

Jim

I find myself mostly only barlowing the 8mm with a TV 2x 1.25" barlow. I've never measured the ER with the 8mm barlowed, but I've never had a problem with the ER being too tight or long either way. Note that the 2.4x Dankin may be the better option for those that want to effectively have two sets of eyepieces in one, with no overlap

EDIT: I'd also like to note that I think the set works fine as is, and most of the time I never use the barlow. 48,32,24,16,12,8,6 is a nice spread for most nights, with the 8mm getting barlowed on only the nights with best seeing. Heck most of the time I'll skip the 24 and 12..Not saying they aren't good EP's as well, but just speeds things along when I'm pushing magnification on planets/doubles :grin:. 48,32,24 is nice to be around for stuff like the Pleiades/Orion nebula though.

Or not. :ubetcha: I think the Brandons and BGO's compliment each other. Brandons excel at lunar, Saturn, double stars, open clusters and such. BGO's - especially binoviewed - are great for Jupiter and Mars. That is my opinion based on my experience so far. But that opinion could change with new experience ... which can't happen if I sell either set.

Do you wear eyeglasses for observing? If you do, the Brandons will not provide enough eye relief except in long lengths.

Mainly, my beloved Carton 100/1300, secondarily my also beloved SPI 60/1200 achro.

It's a love affair, mainly Jesus and my achros (with a nod to my friend Gibby Haynes and Ministry)

I'll keep an open mind, er eye. :bigshock: Problem with BGO's and binoview is I have one set.

Speaking of which, anyone vouch for a Vernonscope bino-viewer?

Only reading glasses here, and I only don them when looking at charts, ipad, sketching, etc. I view bare-eyed and can deal with 5mm ortho ER without clipping my eyelashes (and refrain from blinking).

I can keep my glasses on when viewing through Brandons down to about the 12mm focal length. Even the 8mm and 6mm are more comfortable to me - with my glasses off, of course - than comparable Plossls and Orthos I've used.

The 16mm Brandon arrived yesterday, along with clouds, rain and more clouds forecast all the way out until next Monday night. Per the The Weather Channel app, we may have a few sucker holes in the clouds around 6-7 PM this evening. I have the 60mm SPI sitting by the back door just in case.

First impression is the amazing lightweight, great ER and nice craftsmanship.

Nope, got the eyecup version.

The sucker holes didn't work out this evening, looks like it may be next week before I get to try it out. :bawling:
