The spacer has a male T-thread on one side and a female T-thread on the other. These T2 spacers help achieve a predetermined spacing, e.g. to bring a camera into correct position. By combining different spacers the overall distance can be set quite precisely.

Specifications:
On telescope side: T2 Internal thread (M42 x 0.75)
On camera side: T2 Internal thread (M42 x 0.75)
Length 7.5mm
Black anodised and knurled

Other sizes are available 5mm, 7mm, 20mm

These 3.5 nm H-alpha Enforced-Narrowband Filters open up the extremely narrow 3.5nm H-alpha world.
This enforced contrast results in even fainter stars, providing more signal of faintest nebulae detail. Manufacturing such ultra-narrow filter does require extreme coating homogeneity and very high CWL precision, which these filters are designed for (CWL= Center-wavelength).
