Lasermate collimator..

I just got one of the new-fangled Orion "Lasermate" collimators - the new kind with the optical window.

I am not one to generally endorse products, but these things are fantastic. I borrowed one from a friend last month and was blown away at how easy it makes to collimate a newtonian, even in the dark.

I double checked the collimation with my chesire, and it was perfect.

If you have a newtonian - do yourself a favor and get one of these things. It is really nice to be able to collimate without going back and forth from the end of the telescope to the eyepiece.

I have the LaserMax and it is wonderful!
The grid has places for aligning the focuser and scondary together. It also has crosshairs that show the primary is square to the ole in the mirror box. It also shows the secondary shadows placement in the barrel of the scope whether it is centered of offset.
Great stuff. Hard to think of not using it.
