Hi all,

 

Wondering if Baader makes a Clicklock adapter for a 1.25 diagonal? I looked on the Baader website but couldn’t find one. I just find it easier to swap EPs with a Clicklock instead of the set screws. I know Baader makes a 1.25 diagonal with the Clicklock attached but I want to keep using my Tele Vue Everbrite.

 

Thanks 

Brian

Just to clarify, your current diagonal is the 1.25” everbrite version? If so, no, there really isn’t a good way to accomplish this (short of maybe using a 1.25” nosepiece to T2 adapter, then t2 to clicklock, but that would be a pretty tall, akward, and ugly setup).

If your diagonal is a 2” everbrite then yes, they sell 2” to 1.25” clicklock adapter:

https://www.baader-p...-part-15b).html

Best option though is to get a baader t2 maxbright diagonal, 1.25” (or 2”) nosepiece, and t2 to clicklock adapter. Setup would be very similar in size/weight to the 1.25” everbrite.

You could put a 1.25" nosepiece onto this part :

I second getting a Baader T2 diagonal as a much better option.

You probably already know this, but the one you linked does not have the clicklock style holder. The body is in stock here though (but you’d need to buy the nosepiece and eye holder separate, so would end up more expensive):

A quick Google search showed only 1 in stock and that's with MHzOutdoor.com in Italy, but they ship to the US.

 

The Baader Prism1 diagonal comes with a helical focuser eyepiece clamp, not the ClickLock.  I use one and it's nice for fine-tuning focus if your OTA doesn't have a microfocuser.

 

If you want the 1-1/4 ClickLock you probably need to buy the three pieces separately:

- T2-01C diagonal body Baader #2456005

- T2-14, 1-1/4 T2 nosepiece Baader #2458105

- T2-08, 1-1/4 ClickLock eyepiece clamp, Baader #245100

 

In my T2 diagonals, rather than using the 1-1/4 T2 nosepiece, I use the 2" T2 nosepiece, but still use the 1-1/4 eyepiece clamp. (ClickLock or Helical).  That eliminates the need for using a 2 x 1-1/4 reducer when using only 1-1/4 eyepieces in a 2" focuser. The older T2 2" nosepiece is T2-16, Baader #2408150. The newest one is T2-16A, Baader #2458130.  I prefer the newer version with the small safety kerfs rather then the undercut on the older version.

All pieces are available at AgenaAstro and other retailers. The Baader 7-digit number is Baader's official number.  The T2-XX is a designation used pretty much only in NA I was told. You can usually search by both.

 

Good luck.

 

Gary

 Hi all,

 

Thank for the responses. Something went wrong with the link I used. The attached is the piece I am actually looking for.

 

Thanks

Brian

Yes that's the diagonal you linked to earlier which does NOT have the clicklock eyepiece clamp.

Wow, thanks for pointing that out. I just assumed the end piece was a Clicklock…

The eyepiece clamp on the diagonal you linked is the one that doubles as a helical micro-focuser.

I read that, thanks. I guess this is more useful for imaging but is there any real value for naked eye observing?

 

Thanks

It can work like a fine focus knob. I actually personally find it too fine in my experience though.

Hmm, might be worth a try for me. With my old eyes I sometimes struggle to find the sweet spot.

If your telescope does not presently have a micro-focuser, it's helpful at high power for getting the precise focus of small objects.  

 

The typical use for me is when I'm observing the planets or moon in my SCT and don't have the Crayford focuser attached (it has a micro-focuser already).  Standard SCT focusing is done by moving the primary mirror which can shift the image a little while adjusting, and I have difficulty getting the focus just right at high power. So, the T2 prism diagonal with the helical focuser on the eyepiece holder allows me to make fine adjustments to a sharp focus without touching the focuser on the SCT.  In this use, I'm on a tracking mount and usually well over 200X looking for minute details.

 

The other eyepiece clamp with the ClickLock works well too,  and is the one I usually use when in 1-1/4 mode swapping eyepieces a lot as I move to different objects.  I sometimes change the eyepiece holder while viewing - it's easy enough to do, they just unscrew from the diagonal.

Just be careful which you get, baader has at least 3 different 1.25” eyepiece holders, all look very similar as you’ve found out, only one had the helical focus feature.

Thanks for all the great information all. I think I will give the helical micro-focuser a shot. This leaves me looking for someone who has the above in stock again.

 

Does anyone know if the piece has been discounted or it it just supply chain issues like everything else today...

 

Thanks

Brian

I'm under the impression its the one I pictured above with the EYEHOLD-2 holder. Does this sound correct?

 

Thanks

I suggest getting on the Baader website and looking at all designs. There’s good info there. The complete T2 diagonal you originally referenced as PRISM-1 has a Baader part number of 2456005K. The K designates it as the full Kit rather than just the diagonal body. Internet search by that number too.

Showing the difference in the eyepiece holders being discussed ….

 

The helical focuser has three tightening thumbscrews for minute centering adjustments, but this also makes it take longer to change eyepieces. The 4th thumbscrew is to lock it so it won’t turn. 
 

The ClickLock holder had a diopter adjustment, but that’s not needed unless using it on a binoviewer.

I couldn’t find the full kit in stock anywhere, but the pieces are, will cost more though. No idea when kit might come back in stock. The parts you’d need are:

https://agenaastro.c...crofocuser.html
https://agenaastro.c...1c-2456005.html
https://agenaastro.c...14-2458105.html

Also note these, and the kit you linked, is the prism version. Prisms are good for slower scopes (at least f7 or greater), but the maxbright mirror version is a better option for faster scopes, and more durable to clean (but also more expensive):

This is a link to the Baader catalog that shows all of the options with part numbers. 

 

https://www.baader-p...s_t_2_and_2.pdf

 

Pages 6,7 show the T2 mirror diagonals,  8,9 show T2 prism diagonals, 16 shows T2 nose pieces, 17 shows T2 eyepiece holders.  I have this page bookmarked.

 

 

MHzOutdoor still has one PRISM-1 with the helical focuser in stock:

Thanks all again for the great info!

FYI, I will be using this diagonal with my F8 FS-78.
