The Howie Glatter laser collimator projects concentric rings via a holographic reticle and is inserted into a self centering adaptor provided by Officina Stellare.
You can also replace the concentric ring reticle with a straight through 1mm aperture stop to project a spot on the secondary for axis alignment.
