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! :grin:

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

Gotta agree with those mentioning the 28mm RKEs...for lunar at outreach events, these are an absolute must. Bought them on a lark cuz of all the hype, but man do they surprise, and not just for their "special effects" factor--they actually show better contrast on the moon than our ES 24mm 68s (which are comparable to the Pans). According to a recent mailing we received, they can still be had for $68 despite the recent price increase.

Now we are on the RKE bandwagon I'll have to add my vote for these too.
Amazing with a towel or something to block out everything else, and much better than a single RKE 28. I don't have but have been told that the RKE 21's are just as good...in fact a bit better as there is not the huge eye relief that the 28's + binos have.

+1 for the 28mm RKEs. I do a lot of double star and open cluster observing with them and on wide pairs they are amazing!

Could you please explain how? I'm considering picking up a pair. You can PM me if you feel it necessary, thanks.

Two good zooms are an excellent option. I use a pair of Mark III Baaders. I also have a couple of 28mm RKEs. With a couple of GPCs, one has all magnifications needed for DSO, solar, planetary and double star observing! :cool:


How is the Mark III bino pair working out for you? I recently bought a second Mark III but haven't had a chance to first light them in my binoviewer. It seems, though, that my 65mm IPD seems adequate for the job.

Well, waiting for my Pan 24 pair and my second Leica.
I do have my RKE 28 pair ready to go.
All that aside, just waiting for some free time and a clear sky to match up!
