Review on Alstar Alignment Generation Collimator Telescopes Camera & Photo by David Robinson
NO ! NO ! NO ! - Accessory
I doubt this is an isolated case. After the battery is installed and I turn on the handle the laser does NOT stay on and you have to touch and move the handle to make it stay on. There was a bad connection somewhere in the laser but it was NOT there , where the battery compartment was. I say so you don't have to waste time sending it back after you get a little upset, just spend a few bucks more on a reliable brand name laser peace to all
- Designed for reflecting telescopes, with detachable 2" adapter, both fitting standard 1.25" and 2" diameters. Collimating red laser beam with 7 brightness levels, wavelength 635-655 nm; Output power: less than 5mW, much safer for your eyes. This robust laser unit allows you to align your Newtonian telescope quickly and accurately. Only when the optics are precisely aligned with the collimator can the telescope offer you all its capabilities.
