Product Info
Manufacturer Description
Baader's New VariLock T-2 Extension Tubes give you complete adjustability to enable you to exactly set or vary the spacing between T-2 components. Perfect for exact positioning of reducers, coma correctors, and other optical or imaging system components.
The VariLock extension tubes feature an accurately engraved graduated scale for an easy visual determination of the tube length (0.5mm graduations). Simply rotate the inner tube until the desired length is reached, then tighten the lockring with the included spanner wrench.
Full internal threading and blackening kills any stray light reflections. 2" OD enables use in any 2" system.
As an added bonus, the external T-threaded portion can be removed and replaced with a dovetail ring (included) that inserts into standard camera T-rings (not included), for use with DSLRs.

Ideal Variable Spacer
Pros: Cons: Comments:When changing imaging cameras with slightly different back focuses, I was continually looking for various spacers to get the distance 'close'. This well engineered product allowed me to just dial in the new spacing with very little effort.

Jun 30, 2017Nice Accurate Method To Set Backfocus
Pros: Cons: Comments:Dialed in the settings I needed and tweaked with dial calipers, beats trying to get combinations of rings to work for my CCD camera.

Feb 26, 2017Ideal to get the backfocus right for reducers / flatteners
Pros: Cons: Comments:Very well constructed. Even comes with screw-on end cap which is a nice touch. Now, please make one for M48...

Dec 31, 2016usefull piece of equipment
Pros: Cons: Comments:Works great for getting right distance between ccd chip and focal reducer. Just dial in distance you need and lock it down with the wrench provided with it.I had to use a t-2 extension and the variable lock to get my distance. makes for a very ridgid setup with no flex for camera to scope

May 30, 2013Must have for your AP toolkit
Pros:Accurate,Lightweight
Cons: Comments:I use this to take up the backfocus in one of my imaging setups (an f/4 imaging newt and a DSLR camera), where I use the Baader Rowe coma corrector. I don't use an off-axis guider, so I needed this to take up the backfocus that the OAG otherwise would. Works like a charm, and my field is flat and coma-free.

Feb 8, 2013Great, do your math twice!
Pros:Strong Construction,Easy to Use,Lightweight
Cons: Comments:I bought this to use with an ATFF and an ATCC with my new camera setup. Unfortunately, I did the math wrong and it turned out I needed a shorter one. My loss! But, this is an awesome product. It's orthogonal and it's solid! Definitely takes the guessing out of the correct spacing required.

Sep 21, 2012Perfect for astroimagers
Pros:Accurate,Strong Construction,Easy to Use
Cons: Comments:The Baader Varilock is the perfect tools when you need a non standard back focus adjustment for you field flattener or focal reducer. It's easy to set and the locking is very strong ensuring that the set length will not change over time.

Nov 7, 2011Fantastic equipment...
Pros:Strong Construction,Compact,Easy to Use,Lightweight
Cons: Comments:Had an issue the other day in that I needed some variable distances between two camera's and my field flattener. Tried everything and wasted a bit of cash until I used the Baader Varilock which solved my problems. Excellent construction and easy to use. Managed to get very accurate measurements to fill the space between my camera and my field flattener. Only wish I bought this first up.....
