Product description

Baader VariLock T2 extension tubes

Baader VariLock T-2 extenders are two infinitely adjustable T-2 system™ extension rings. The lockable T-2 extension tube is infinitely adjustable from 20 to 29mm by using a spanner and Hex key. The extension tubes can be set by first loosening the collar, adjusting to the desired length using the millimetre scale, and then tightening the collar again. A locking tool for the collar is included in delivery.

VariLocks are an ideal aid for adjusting the exact focusing distance, e.g. for Ha solar filters or image field correctors with a critical field stop position.

Another application is that, with both VariLocks, the T-2 thread on the eyepiece side can be removed by loosening the grub screws (Hex key for this included in delivery) and replaced with a dovetail ring which can be used to connect directly to the appropriate Baader T ring for EOS and Nikon DSLR cameras.
