TSVF215 Extension Sleeve - 2" filter thread - 15mm

Extension sleeve 2" with 2" filter thread on both sides
Length: 15mm

This adapter has proven to be very important in many areas of astronomy. The extension sleeve is simply screwed into the filter thread of 2" eyepieces or 2" adapter and thus extends the insertion sleeve by 15mm.

On the telescope side you can screw in a filter or even adapt an additional extension sleeve. So you can extend the socket almost arbitrarily, without reducing the accuracy of fit, as with plug adapters that can tilt.

Specifications:
- Metal sleeve: black anodized - double-sided 2" filter thread (48mm)
- Overall length: 15mm
- Length of M48 internal thread: 5mm
