Sirius Optics 2x Barlow With M42 Thread 1.25 Inch

This Barlow lens provides 2x the original magnification when used with any 1.25" eyepiece. Its 1.25" barrel size makes it compatible with most modern telescopes and eyepieces. 

It is equipped with a male M42 thread, which can be attached to a T-ring for easy DSLR or CCD camera mounting. The lens component may be removed, allowing usage as a non-magnifying T-adapter. 

Features a doublet lens system, with baffling on the interior to eliminate light reflections and increase contrast.
