Baader 2" ClickLock clamps – available for many brands and sizes
A small rotation by 20° with gentle fingertip pressure to the knurled lever is enough to securely clamp every 2" accessory.
Ratchet function – features acoustic and haptic display of the clamp-position. This way you can hear and feel in darkness without looking if the clamp is opened or closed.
Compression tension-ring of thick-walled hard bronze, keeps its shape even after many years of use and holds expensive accessories securely - without causing scratches or pressure points on your accessories.

I have a Celestron Edge HD 8" SCT. After a few months using the 40mm kit eyepiece, I'm looking to purchase a couple of Hyperion eyepieces. What ClickLock components would be required to mount this?

Which 2" Baader Clicklock will suit my Orion ED80 CF?

Question by: Rocky on Dec 3, 2017 6:02:00 AM | 1 Answer(s)

I recently purchases a 2" Baader Clicklock visual back to use with my EdgeHD 8" SCT. My issue is that the system is too tight and binds up. When I put a 2" diagonal or eyepiece into the clicklock and go to lock it I can only get about 1/2 of the rotational movement before it gets tight to the point of binding up.

Is this an issue or is it designed like this? I also thought that the part would be smooth when rotated, but I can feel distinct clicks so to speak. I just want to make sure that this unit is good and not defective, and I have never use this type of system before

I have two questions about the 2" ClickLock 2" CL-Extension 47mm.

1) How long is the overall length of this adapter including the 2" nosepiece. I know the optical length is 47mm, so how long is the attached 2" nosepiece?

2) How deep can a 2" eyepiece be inserted into this adapter? I have a 2" eyepiece with a 38mm nosepiece. Will I be able to seat it all the way in?

Thanks,
Steve

i have a C8 edge hd 8" sct with baader 2" click lock and I would like to use my nikon d5300 with an adapter, with which to use a filter without using the UFC. What could I buy?

Question by: Christian Trivellato on May 17, 2019 6:24:00 AM | 1 Answer(s)

The 8" EdgeHD has got a backfocus of 133mm, the SC-Clicklock is 47mm long.
For an APS-C-camera, you can use T-2-adapters without problems and don't need a larger diameter for the adapters. So, you can use the standard T-ring, which gives you 55mm backfocus for the DSLR.

To adapt the APS-C-camera to the 8" EdgeHD with a Clicklock, we'd recommend
- 1x T-Ring Nikon to T-2 # 2408300 (55mm backfocus to the camera sensor)
- 1x Baader VariLock 29, lockable T-2 ExtensionTube 20-29mm with spanner tool, set to 28.5mm, # 2956929
- 1x Baader 2" / T-2 Nose Piece and Camera adapter # 2408150 (total length 2,5mm)
- 1x 2" Clicklock #2956220 (length 47mm, you already have this part)

This gives you a total length of 133mm without a filter.

You can screw any filter with a 2" housing into the 2" nosepiece (just like into any eyepiece). The filter will move the focus outwards by ca. 1/3 of its thickness, so a 2mm filter will move the focus about 0.7mm outwards. If you set the Varilock to 29mm, you are within the 8" EdgeHD's specified working distance of 133.35 +/-0.5mm.

A full-frame camera would require a Wide-T-Ring to make use of the full aperture; for the smallet APS-C, the T-2-combination works fine.

Hi,

I own a Celestron EdgeHD 9.25 SCT with CPC mount. It comes with 2" back and 2 inch diagonal. Can I replace the back with the #2956233 SCL (3,3")-ClickLock and then interface the Baader 2" ClickLock Diagonal Mirror# 2956100 ? I don't see this combination described in your documentation. If I missed it, apologies.

This would allow me to easily rotate the diagonal if needed and would appear to keep focal length very close to original. There is no problem with zenith rotation of OTA.

Any comments on doing this are appreciated.

Thanks!
Fran Doherty

What would be your suggestions if I would like to use the Baader ClickLock system for visual and/or AP, keeping in mind the required 105 mm from Reducer to camera sensor by Celestron, and do I need the Celestron T-adapter also?

-1

Question by: Ernest Joyner on Jun 6, 2017 9:45:35 AM | 1 Answer(s)

The SC-Clicklock has got a length of 47 mm, the distance from a T-2-adapter to the sensor of a DSLR is 55mm. Our T-2/2"-adapter #2408150 adds another 2.5mm, so you are at 104.5 mm which meets the tolerances pretty good - Celestron gives a tolerance of +/- 0.5mm for the EdgeHD. You may use the Baader T-2 adjustment/spacer-rings #2458102 for the perfect distance. The Celestron T-adapter is not required then.

Visual use is a bit complicated, because a star diagonal like #2956100 already has got an optical length of 112mm incl. Clicklock clamp. You can remove the nosepiece, then you'll have a 2"-thread with which you can attach it directly to the reducer - but you'll need the NexStar Locking Ring #2458270 to rotate it into a convenient position. It is 5mm thick - please check if the thread at the Celestron reducer is long enough.

But for visual observation, it is not as critical as for photography - we even have customers who have adapted a focuser to an EdgeHD and are happy with the results.

Question by: Richard Darn on Sep 20, 2018 3:13:00 PM | 1 Answer(s)

Recently purchased a Celestron 8" EdgeHD SCT. Not happy with the standard visual back setup. I'd like to replace it with the Baader ClickLock system. The EdgeHD visual backs are longer than the standard visual backs. Mounted on the base (3.3"?) ring is a tapered, faceted cone, providing additional length. Apparently this is to take advantage of the EdgeHD’s optimum image size which is farther back than the same position for a standard SCT. Three questions:
1. Do I leave the base ring on the SCT (it's mounted quite tight, I haven't been able to remove it with normal force), and just use the 2" threading? Or do I remove the base ring (with extra force?) and use the 2" Baader ClickLock with 3.3" clamp?
2. Do I need to compensate for the extra length of the standard setup cone? And if yes, how is this accomplised?
3. If I want to use the Celestron .7x Focal Reducer for the 800 EdgeHD, I'm assuming this goes between the SCT and the Baader ClickLock?
Appreciate your feedback. Thanks in advance!

Description

Details

The Baader ClickLock®-System (1¼" / 2") in an overview

Never before has an eyepiece clamp for amateur astronomy been so elaborately crafted.

Das Baader ClickLock System - 1.25 und 2 Zoll

Heaviest tested load: complete C14 with SCL 2" ClickLock clamp and a 2" ClickLock mirror diagonal with Scopos 30mm Extreme eyepiece. Attention: not recommended for imitation!

The Baader ClickLock (1¼" / 2") is a precisely fitting, very massive eyepiece clamp without clamping screws (!). Inserted eyepieces, CCD cameras and similar accessories are securely held in place, locked against rotation and won't be scratched in any way! With a small turn of 20°, each eyepiece is firmly clamped. You will never have to handle small locking screws again – instead, just rotate the top of the eyepiece clamp for a few degrees, and the eyepiece will be firmly fixed. This is also no problem with gloves on!

Our various ClickLock clamps are made of seven precision-machined components which provide a highly effective retention mechanism that securely holds any 1¼" or 2" eyepiece. The clamp is very expensive to assemble, the price therefore initially may appear high for "nothing more than" a clamping device. But if you think about the comfort, precision and stability, it's well worth the money.

You do not have to tighten the ClickLock clamps with brutal force, because the mechanical principle comes from professional mechanical engineering. This is how the tool holder in modern CNC milling centers works. Clever use of leverage multiplies the torque. The inserted object is held on three sides similar to a quick-action chuck and can therefore no longer carry out any tilting movements.

Detailed information about the 2" ClickLock system

Example of switching a standard 2" clamp to 2" ClickLock

We have tested the effectivity and stability of the ClickLock mechanism for many years with the 1¼" ClickLock clamp.
The 2" ClickLock system is designed to be much more mechanically solid.

Even a 20° turn with light pressure of the rotary lever is enough to hold all 2" accessories absolutely securely and firmly.
Ratchet function – indicates the position of the clamp acoustically and haptically. So you can know if the clamp is open or closed in the dark and without looking.
Massive tension ring – keeps even the most expensive accessories absolutely safe, without causing scratches and bruises
The position of the rotary lever is adjustable for left-hand / right-hand use either by six camera slotted screws or by six Allen screws with a hexagonal wrench (depending on the model)
The heaviest tested load to date is a complete C14 with an SCL-clamp and a 2" Click Lock star diagonal with a Scopos 30mm extreme eyepiece. The C14 has been lifted on the eyepiece. We emphasize that this test setup is not is recommended for imitation.
The extensive range of ClickLock clamps makes it possible to retrofit the Baader 2" ClickLock clamp on many telescopes

With the 2" Clicklock clamp, you can also convert e.g. your 2" Maxbright mirror (or the 2" universal prism) to the Clicklock system, simply unscrew the old 2" clamp and screw on the new 2" Clicklock clamp.
