Farpoint 2 Inch Collimation Kit with Carrying Case
This collimator is well made but mine wasn’t collimated dead on when I received it. I had to tweak the adjustment screws and fool with it for about an hour to get it just right. The real problem is that the 2” barrel does not have a flat surface behind it to butt up against what ever it is inserted into. Instead, the surface has a chamfer on it which makes it difficult to ensure that the collimator is precisely parallel to the focuser/optical axis. I’m probably going to take it to a machinist and have that rounded backstop machined flat so that I can just insert the collimator into a 2” ring adapter, press it all the way in against the newly machined flat and tighten it down. Only then am I assured that it’s properly aligned for collimation.
I am loving it. I am using with the Celestron XLT 150 F/5 newt and it makes collimation such a breeze. So much more reliable than the cheap $30 amazon laser collimator... not even in the same league...
Very high-quality items! I can finally quit worrying if my laser is out of calibration and just use the tool. If your scope has a 2" Focuser it only makes sense to use a 2" tool. The carrying case is a nice touch as well.
This collimation kit is so much better than the original collimator that came with my Z12. The collimator fits perfectly in the draw tube without moving around and shifting the laser beam. I haven't been able to use the cheshire piece in the dark yet--I need to figure out how to do that by shining a light down the tube. Instead, I just adjusted the primary to bounce the return laser beam into the outgoing beam (as shown in the Farpoint video), and the scope seemed to be very well collimated. If I get brave enough to remove and clean the primary mirror sometime, I will add the triangle marker to the center of the mirror for more accuracy. I'm happy with my purchase.
This was just what I needed to get my 6" f/4 imaging newt collimated for deep space photography. I had been struggling with other laser collimators, but this one is perfectly centered, well machined, and the dot is tiny compared to the normal cheshire style laser collimators. The center spotting triangle is also a game changer compared to the factory circle on the primary, takes the guesswork out of centering.
