This laser collimator is like new. I have used it once on a Mak Cass, and I later realized that these are best used for Newtonians. So, I am selling to get a little of my money back and to give it to someone who can use it.
This collimator has the grid pattern hologram with the bright central dot. I don't believe that holograms are offered any longer from Helix. I found the grid to be an excellent aid in centering when I tried it.
This collimator does NOT come with the 1.25" to 2" adapter.
