Baader Varilock 46 Lockable T-2 Extension Tube
Baader VariLock 46 Lockable T2 Extension Tube with Spanner Tool
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 H-alpha solar filters and field correctors with critical focus position.
As a further application of the VariLock by loosening the set screws (Allen key included) the included T-2 threaded barrel can be removed and replaced with a dovetail ring, which then can be fastened directly to a T-ring for our Canon EOS or Nikon DSLR camera.
