Baader VariLock 46 - lockable variable T2 extension tube 29-46 mm
The Baader VariLock T2 extension tubes are two continuously adjustable extension rings in the T2 system. The extension tubes can be adjusted to the required length by loosening or locking the pretensioning ring using a millimetre scale. A locking tool for the pretensioning ring is included in the delivery.

VariLocks are ideal tools for setting exact focus distances for, for example, H-alpha solar filters or image field correctors with a critical focus position.

As a further application, the T2 thread on both VariLocks can be removed on the eyepiece side by loosening the grub screws (Allen key included in the scope of delivery) and replaced by a dovetail ring, which can be fixed directly in Baader´s Wide-T-Rings for camera mounts like EOS, Protective for Canon, Nikon F bayonet as well as all other rings with 52 mm dovetail ring.

Properties:

The Baader VariLock 46 is more than a simple T2 extension. It is a complete adapter system for achieving exact focus distances:
continuous adjustment from 29 mm to 46 mm
high stiffness due to sufficient body wall thickness
reproducible adjustment by lateral millimeter scale
the T2 thread on the camera side can be replaced by a connector with dovetail ring for the Baader Wide-T-Ring adapters
complete tools (clamping wrench, Allen key and connection piece) included in the scope of delivery


Application areas:
Exact adjustment of the focus distances for sun filters, image field correctors, ...
Reproducible results with adjustment to adapters with different lengths by millimeter scale
With the Baader bayonet adapters a quick bayonet mount connection of various cameras is possible, see recommended accessories.

"Hilfreiche Verlängerungshülse um notwendige Abstände zw. Optik und Sensor zu optimieren. Ggü. den preiswerteren Pedants bietet die Baader-Verlängerung saubere und ""geschmeidige"" Gewinde, eine gefühlt deutlich höhere Stabilität und die Möglichkeit, den ermittelten Abstand sehr sicher und ohne Verkippungsgefahr zu fixieren. Notwendige Werkzeuge zum Arretieren und Löen werden mitgeliefert!"
