I had a pair of 19 Pans and loves them until I replaced them with 16T5 Naglers.

What is the minimum Interpupillary Distance (IPD) required In order to consider Binoviewing with the Leica Aspheric Zoom?

I have not yet purchased a second ASPH, so this is a best guess, As I have sucessfully binoed a pair of Meade series 4000 SWA 24.5 mm eyepiece with my 61 mm ipd, ( and the ASPH,s are close in diameter and shape to the meade,s ) I think about 58 + mm will work ( also my wife who is about 57mm ipd could use this setup). But much depends on your nose and forehead ridge shape.

EDIT: I just looked up the diameter of the ASPH and it is 59mm so and IPD of 59 mm or more is needed + nose room!

Ok! I'm a tall guy with a proportional IPD: 68mm.

Looks like I may have a shot at being able to do this!

Cool!
If you do get two and bino them? some things to consider:
the APM 1.25" adapters should have the least in-focus about 20 mm,
The starlight adapter, maybe 33-34 mm.
I like the Starlight adapter because it is removable without tools ( and I like to store the ASPH in its case which will not fit the adapter too).
So it depends on how much infocus your scope has?

Well, when BV'ing, a short(er) light path is always desirable. My current Leica has the APM adapter, so I'll have to try it once I get a second unit, in that format.
I'm fortunate to have more than one scope to choose from, and at least two of them (the CAT's) shouldn't be an issue.

Now to scare up a second Leica!

Levine,
Could you please measure the shoulder on your 1.25" APM adapter? ( the distance from the shoulder of the eyepiece holder to the top of the adapter)
I am working from pictures to see how much this adapter raises the eyepiece above the top of the eyepiece holder ( My best guess is 12mm or 0.475 inch).
Thanks,
Rex

Rex, for the moment, I have the 2" holder, which I am looking to swap out for the 1.25".
I imagine the measurement would be similar, in this case, exactly 1/4".

The 1.25" adapter is longer in the shoulder than the 2", as the bottom of the Leica has to fit in it and the leica is too wide to fit inside a 1.25 barrel.

hmmm, the first set i have bought was two volcano top university orthos. a total cost of $110 these are sill the easiest eyepieces to use. Planetary performance is great as well. if i were to buy new eyepieces i would go for the Edmund 28mm rke pair Also some great info is on a thread going in the eyepiece forum labled favorite pair of eyepieces.

oa yea, the 18mm pentax pair are awesome on the sun with the wedge! these are also easy to use. i wouldnt go less than 10mm with the mkv the eye relief is too short and images don't merge , on my mk4 i can collimate it but have found that the elements in the eyepieces are not in the exact center and as i rotate the eyepiece the image also rotates in and out of alignment.

Levine, does your FS-128 reach focus with your MarkV and 1.2X GPC ?

Just received my Mark V! In the process of getting some EP pairs together.
My first set, the Pan 24's, should be here any time.

Did you get the Mark V "kit" as sold by Astro Physics? which includes Baader T-thread diagonal/ with quick release bracket, 1.25 GPC, and AP nosepiece?

Yes!
Purchased as new from someone on the Other Major Astrosite; it had been out under the stars a grand total of TWO times...!

Hi Rex,

If you are still looking for this measurement, I just checked my 1.25" APM adapter and the distance from the shoulder of the eyepiece (where it rest on eyepiece holder) to the top of the adapter (surface which Leica eyepice rest on) is 17mm on my adapter.

By the way, if anyone is looking to purchase a "like new" 1.25" APM adapter send me a PM. I am now using a Starlight Instruments adapter with my Leica Zoom.

Best regards,

Keith
