Practical 4" extension for FLT 110 and FLT 132: very useful if you use a CCD or need more dratube extension but still expect to flexure in your train.
Fully anodized, and compatible with other similar telescopes. Male & female thread. It can accept our TMB field flattener for FLT.
To mount on the telescopes, simply remove the 2" nosepiece adapter from the scope and thread the extender in.
