Howie Glatter Self-Barlow attachment

The self-Barlow attachment is a disc with a white screen on the front and a small integrated Barlow lens in the center. It screws onto the aperture of the Howie Glatter laser collimator (sold separately) and offers a very compact way to perform Barlowed collimation. As with standard laser Barlow collimation, the shadow is projected onto the screen at the focuser side: adjusting the mirror at the bottom of the tube can therefore be inconvenient in some cases, especially on long focal length reflectors.

This is the new "NV" version with coarse threading. The attachment fits all Howie Glatter and Starlight Instruments laser collimators that feature the new threading (indicated by "NV" in the product code). If you own an older version of the laser, dating back to before 2020, please contact us before ordering.
