Baader T-2 VariLock extensions are two infinitely adjustable rings in the T-2 System. By loosening then after adjustment locking the clamp ring the extension tubes can be adjusted to the desired length by using a millimetre scale. All necessary tools (allen key, hook wrench) are included.
VariLock is an ideal tool for setting the exact focus at distances when using field correctors with critical focus position.
This Lockable T-2 Extension Tube can be adjusted between 20 mm and 29 mm with clamping and Allen key.

I needed to achieve a distance of 23.5mm, very easy to achieve with this. Excellent.

This is what it is, just a variable spacer, but the quality of the materials and the way everything precisely fits together makes this a superb piece of kit. Other than a filter, this Baader item is my first for the optical train and the way it marries up my other components keeps everything stable. Thanks Flo for the resolution to a problem and accurate advice as always.

Haven't had the chance to use due to weather, but have fitted it and I can see it will be useful for getting the back focus right for the reducer.
Quick delivery as always.

Do what I need but expensive ! , The only problem is: I buy to use with a ZWO 1,25 filter wheel and the 42m screw was to deep u touch the filters , so I have to buy t2 spacers to avoid this situation , 4 stars because of price and baader have to sell this spacers for wall application , in my case was only a 1mm spacer
Made my life much easier.

I was having problems setting my coma corrector back focus to account for my 3mm thick Astrodon filters. Using this I made something like 30 fine adjustments to the coma corrector spacing before I was satisfied. Yes I could have used spacers but that would have driven me mad. One Star dropped for pricing.
Massively flexible (in a good way!) and high quality.

Really good quality, and lock firmly with no flexture, which I was a little worried about. I'll probably end up buying its big brother too. Highly recommended.
