Everything seems to come with one of these! Not necessarily a problem, since they often function as part of the dust cover for whatever they came with in conjunction with a 1.25" plug, and it's nice to always haven them handy when you need them. Still though, I'm at 5 and counting, and I don't own anywhere near as much gear as some of you.

For each of my two telescopes, I have one Clicklock adapter and one Televue Equalizer.

Having several scopes, I also have several size eyepieces - not just .965, but several different size microscope eyepieces, plus the odd size ones, so I ended up making an adapter for each one, figuring why keep pulling the eyepiece out and putting a different one in, just go ahead and make one for each. So I bought a box of 18 adapters here on Cloudy Nights, plus a few more here and there, so a lot.

  Not enoughlaugh.gif! I was looking over my kit today just hoping for a chance to set up my XT for some viewing and upon inspecting my focus travel and cleanliness (after a long life in the closet), noticed my 2"-1.25 is slightly " Out of round" when chucking a sight tube in it, it wiggled a tadtongue2.gif. I suppose I could use the RC's adapter, it is a compression type but it is taller than the factory version. Guess I'll check classifiedslol.gif! ( Not enough in focus for direct threading the G3)

I use two.

 

One has the 1.25" hole sit above the level of the 2" part.  The other has the 1.25" hole recessed so that it sits just below the 2" hole.  This allows some eyepieces to be used in scopes that have limited draw-tube travel, and having a little more "in" travel makes just enough of a difference in being able to focus with some eyepieces or not.  My default adapter is the first one mentioned.

Two.

One with my 8" newt and one with the diagonal I bought to use with the mak that still hasn't arrived.

 

I'd like to use the one from the diagonal on the newt because it has filter threads and compression ring, but it doesn't fit very well in the newts focuser.  Wouldn't mind having a better one to use with the newt.

I currently have four, but I actually plan on getting a few more.  I want to have one for each 1-1/4" eyepiece that I regularly use in any telescope that has a 2" focuser.  That way I can switch between 1-1/4" and 2" eyepieces without having to worry about the adapter - I would just switch the eyepiece/adapter combinations out like they were 2" eyepieces.

I have 6 for four refractors and two 2" diagonals.  I may have one more in the C11. (not going to look)

 AP 2" Visual Back threads onto the 3.25" rear cell of the Celestron 11 I think I put one in there.

I have about 4 or 5, I think.

 

Am I the only one who is annoyed by the fact that they are not a universal design and therefore not easily interchangeable? I especially don't like the ones where the location of the set screw prevents you from inserting the adapter all the way into the focuser.

2. One came with the Dob, one came with the laser collimator.

In my experience, the vast majority are interchangeable...   sometimes a longer set screw can be useful..

Maybe 4.5?

Having a 2" diagonal on my LX200 Classic, I use maybe 3.5 at every visual session:

#1 - The it-came-with-the-LX Meade adapter lives on attached to my Orion reticle and used to align the GoTo's  brain;

#2 - Bought a used Astrotech diagonal, it's adapter takes care of my Celestron/Baader Micro Guide and is used to fine tune the above alignment;

#3 - Now have a TV Everbright diagonal, it's adapter takes care of my TV Delos 10mm;

#4 - is a glow-in-the-dark NiteEye's adapter that I use as a paperweight;

 

and the .5? -  Does the cylinder that makes a TV Ethos 6mm work in both 2" and 1ΒΌ" count as an adapter?

I have 4 in my accessory box.  And several more installed in my telescopes (that I did not bother to check).  I like the WO Rotolocks and tend to only use them these days.

After selling a few, I have only two now.  One is a precision centering adapter...

I wish that I could count that high.  They breed in my junk box.
