That would be convenient. I have a very nice Baader zoom MK III, given as a very kind gift. I hope someday to find another at a reasonable cost and be able to afford it. Two of those would be nice to look through.

 

The only hesitation I would have is weight. but it might not add that much to make a difference.

 

In the meantime I keep my Astromania (Arcturus) binoviewer in a Pelican 1200 case I've had. It isn't huge, which is actually good, and the 1200s are relatively inexpensive as compared to the larger sizes. Plus there are sources to replace the foam insert.

Inside, I have the binoviewer, eyepieces and several Barlow nose-piece attachments.

Up in the RH corner are the two nose-pieces that came with the binoviewer, the 3x and the 1.85x, and also a Burgess 1.9x nose-piece, which are very inexpensive but work well. Over sitting with the BVer is a William Optics 2x nose-piece. Also a very nice lens.

 

Of course the 1.85x, the 1.9x and the 2x are redundant, but the actual magnification actually varies somewhat. Also, the back-focus distance is a little different with each. So I have to decide which one is best and use it with the others.

 

The eyepieces are all straight barrel types. The 32mm Plossls came with the binoviewer and are nice to use for low power. All the other Plossls are Meade Series 4000 Super Plossls, that again have the straight barrel. 

 

These are very good eyepieces, have a decent FOV and at the FLs I have, 12.4mm, 15mm and 26mm, the eye relief is not nearly as bad as the shorter ones.

Nice case Joe!

You guys (and gals?) have convinced me. I just pulled the trigger and bought one of these today. Now the wait... tongue2.gif

Good time, don't want to miss out on Jupiter and Saturn as they are fading west fast.

Yes they are. From here, Jupiter is too low. The detail suffers from when it was higher. Of course, this year it never got very high. It will take 3 or 4 years to get to a decent altitude.

 

Same with Saturn. But it is at an altitude that is still good foe views. 

 

I’ve noticed something with binoviewing I don’t understand. I’m sure it’s been talked about before, but it baffles me.

 

I had my Celestron 100mm f/9 refractor out looking at Saturn. I brought both my binoviewer and monovision eyepieces to do some comparing.

 

Using a 5mm eyepiece, I was at 180x. Saturn was sharp but small in size. With the binoviewer and a 12.5mm eyepiece and a 2.4x nosepiece Barlow (the magnification checked optically) the magnification was at 173x.

 

But, in the binoviewer, Saturn appeared significantly larger to my eyes than it did with monovision.

 

I reduced the magnification on the binoviewers and found that at 130x, Saturn appeared close to the size it appeared in the mono eyepiece at 180x. I have no idea why this happens, but it likely is due to the eye-brain interpretation. This isn’t the first time I’ve noticed it. It happens all the time.

Got mine and got to test it out. The good news is that (besides the price being pretty darn good, especially given that it has eyepieces) it's definitely a keeper. The bad news is that I don't get to see it again until December 25th... shocked.gif undecided.gif tongue2.gif

 

Oh, and I also measured out the foam lined box and have a hard case for everything printing as I type this. ;)

Here's what I came up with for it's case. This case will go into my main eyepiece case. I included enough space so that the stock eyepieces can stay in their properly focused offsets. The only thing missing is the felt lining, but no hurry because as I've already alluded to, I have quite a while before I'll see my binoviewer again. tongue2.gif

Yep, whatever I get, it seems like there is something that I can draw up and 3D Print for it. Sort of like a hammer in search of a nail... tongue2.gif

In case anyone has a 3D Printer (and actually wants to make one of these), I share a lot of my designs on Thingiverse. Here's this one: https://www.thingive...m/thing:3925338

I don’t have one, unfortunately, but thanks for sharing the design.

 

That is just amazing!  I always said I wish I lived next to someone friendly with a lathe.  Now on the other side, I wish was someone with a good 3D printer. Not that I’d mooch favors without appropriate libation compensation. grin.gif

Any thoughts on using a set of 18mm Baader Classic Orthos in the Arcturus?

They should work very well. Orthos are great, and comfortable at the medium and longer focal lengths. 

 

I use Meade Series 4000 Plossls because they have a straight barrel. At 12mm and higher they have sufficient eye relief to work well.

I've used a pair in my WO bino's. They merge well.

My new Arcturus arrived yesterday to much delight... at the same time as the T2 Amici prism diagonal I or ordered from 365astronomy a week ago. drool5.gif 

After trying it out last night I have a couple questions about the Baader 1.25x GPC. I think I need one. 

1. Where does the GPC go? Does it slide in between the 2” T2 nose piece and the diagonal? 

2. Will it correct both the 1.85x and 3x Barlows that came with the binoviewer?

It should thread onto the chrome nosepiece, which threads onto the binoviewer. 

 

The 1.85x and 3x Barlows will do the same job as the GPC in moving the focal plane out to a point where your scope focuser can reach it.

 

You can, if you wish, thread the GPC onto the front of each Barlow, I believe.  However, the amplification of each the 1.85x and 3x will be further increased by the GPC factor of 1.25x. On the reflector, due to they having usually less focuser travel, you may have to stack the GPC and a Barlow.

 

This is all in the 1-1/4” format. That will have to be stepped up to 2” with an adapter.

Ssayer,

 

Thanks for sharing the design files for the case!  I just had a blue one printed at my library.

 

Clear skies, Mike

Looking for more detail from those using the Arcturus Binoviewer with additional lenses.

 

Thx.

my setup is a classic Celestron orange c8 using a 2” Burgess CED diagonal & Bader click lock visual back.
When needed, been using my Meade 2x shorty barlow (early 90’s) in place of the supplied
1.8 and the 3x opc/barlows and find it to be a good match.

I’ve a pair of Russell Optics 15mm SWA Konig's I ordered that I really like, field of view smaller than expected, but Jupiter, Saturn & moon look fantastic, looking forward to Mars.

Also using a miss-matched pair of 25mm plossels, to some success.
even was able to use a pair of matched 5mm ortho’s (this won’t happen often, had a good night in the ohio river valley).
So long story short, been using the supplied 30mm and find no fault with them,
but experiment with eyepieces

I have a Stellervue SV80 Acess on the way can’t wait to try these BV in them, hoping focusing won’t be an issue.
Yes, still happy i bought these!

Larry

That's my finding too. Great deal and thank you for bringing this product to my attention!

None of those are the 30mm that comes with the binoviewer. I don’t think you can buy just the eyepiece that comes with it.

You are correct.  I don't see the 30mm offered anywhere (which is strange).
