Does anyone know the maximum focus limit on the 2x54s?

For my eyes -- about -4.5 diopters near-sighted --  my super-wide Vixens just reach focus, and my Kasai wide-binos reach focus with ease.

I don't know if they're all the same, but my prescription is:

OD- Sphere -6.75..

OS Sphere -8.25..

 

and I can't quite reach focus without my glasses.  I suspect you would be OK at -4.5,

but don't know for sure.

[Mr. Bill]

IMO, not going to work. Not a lot of adjustment for diopter.

[hoof]

I've been reducing my myopia, but when I got mine, my astro myopia was 4.0 diopters (regular prescription of 3.25 or so). That was right at the limit. I'm down another half diopter and that gives me some good wiggle room.

4.5 diopters is likely too much, though in bright sunlight they might work. If your prescription was determined in the usual dark optometrist office, your astro prescription is likely -5 diopters, thus will need glasses for sure.

On the good news, unlike my Vixens, the Orions work well with glasses. I get most of the field of view with glasses, and the parts cut off are a bit aberrated. so not missing much.

I'd give it a go, the Orions are awesome and do work with glasses.

Orion 2 X 54 binoculars just ordered.  Anyone use eye shields with these gems? Also any current experience with filters.  Tempted to try adapter/filter recommendation of others.  Worth exploring or not?

[PEterW]

56mm filter ring I believe, but impossible to find. I tried to pack out some 55mm ones and it didn’t work too well, though I could just have use some duct tape! Binobandits work to shield stray light, though I’ve made some custom ones too.

If you need more than 20 pairs, I can manage to mail a parcel to one address. Price $20/pair. Please see #171.

Or if you want dedicated 56mm UHC filters(see #166), message me.

PS I'm not a seller of these products, just offer to help.

Use UHCs with very broad bands, such as Baader UHC-S's or Lumicon Deep Sky's.  Narrower bands vignette quite a bit due to off-banding and are harder to focus.  Polarizers work very nicely during the day for cloud viewing.

[PEterW]

Great that there are now adapters available. https://www.365astro...48-threads.html These look like they’d work too.

You're giving up FOV with those rings.

[ButterFly]

You're giving up FOV with those rings.

So what?  One isn't using the rings without a filter anyway, so there is a larger gain in the end.

[Bjnaz]

Yes, understood. The extreme FOV an advantage.  Why minimize the asset? ... unless filtration provides another distinct benefit.  Backyard Bortle 4- 5.  Considering UHCs after un filtered use.  Excited to see the wider view while photo rig looking deeper and on auto pilot!  Thanks.

Thanks. Considering your Rx.

I ordered the Orion 2x54 today through WH Telescopes, my usual route for Orion products.  Bonus points rule.

Just to check, and I apologize for the dumb question.  Can 2" filters be used in these adapters?  That is, do 2" filters thread into the m48 female end?  Or, do you have to buy filters that are specifically 48mm?  I've always seen these (2" and 48mm threads) mentioned as if they are interchangeable, but I have only bought 2" (and 1.25") filters.  I have the Orion 2x54's, and would be very interested in adding filters.

Yes. 2" astronomy filter are standard M48x0.75 male filter thread This is what I purchased: https://agenaastro.c...cls-filter.html

Thanks, Sam.  I'm certainly now considering filters for mine.  It sounds like fun.

The funny thing (if you can call it that) about this whole thing is that by the time you buy the adapters and the filters you've spent more than the cost of the binoculars themselves. Unless you already had the filters of course.

Luckily, I have a set of filters already, so if this doesn't work for me I'm only out the price of the adapters.  Seems that nothing in this hobby is cheap.

Well the sky is free.  No additional charge to view any of the objects,  however where the universe gets you is the tools needed in order to dig deeper

My 2x54 bino came in this morning's mail.  Terrestrially, they seem to work great.  I'll know more tonight.  It's supposed to be mostly clear again.

[robklingel]

I watched the Orion video, seems that he was talking about Dark Skies. I have bright skies. Never ever dark. Any thoughts?

[John Fitzgerald]

I have Bortle 4 or so here.  I'll post my experience if it's clear tonight.  Later in the week, I hope to get out to the B2 site.

You will see more stars.  I know, I'm under Bortle 7/8 skies.  It will not be like looking at a Star Atlas, like they say in the video, but you will see more.  Everything's better under dark skies.

Under brught skies, brighter stars pop out to make constellations an easier find.
