TSVF205 TS 5mm Extension Ring - M48x0.75mm 2" filter thread on both sides

Extension sleeve 2" with 2" filter thread on both sides - length 5mm

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" adapters and thus extends the insert sleeve by 10mm.

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.

Technical specifications:

• Metal sleeve: black anodized - double-sided 2" filter thread (48mm)
• Length: 5mm
• Length M48 internal thread: 4mm
