A Beginner’s Guide to Collimation
Collimation is a lot like routine car maintenance. It isn’t why you bought the car, but you still have to change the oil and check the tire inflation once in a while to keep the vehicle running properly. But then again, you’ll also find people whose idea of a good time is to spend a Sunday afternoon under the hood of their car. Some people just like to tinker. And if you’re a telescope nut, collimation can be a form of tinkering. But the thing to remember is that it doesn’t have to be. Most of the time your scope’s optics can be aligned in a minute or two.
If you like playing with lasers and fiddling with knobs more than viewing the night sky, well, you’re probably better off reading someone else’s collimation instructions. I’m here to get you up and running with a minimum of fuss and heartache.
I haven't done collmation yet but I'm starting to learn about it. There are both short & long Cheshire collimators. It's looking like the long ones are also meant to be used with refractor telescopes also.

sherlew99: What a fascinating concept. Well the air above would occupy an area of space. Plus the basic word "space" is just a common term that fails to include the vast, wonderful weirdness out there between all objects out beyond our world.

sherlew99: Sorry I missed your message. Don't remember precisely what I was doing that day. Was probably doing a lot of online news reading, though. The upcoming Trump administration has me worried.
