Just got an RC8 scope. Dont really want to perform acrobatics in my observatory leaning over the front of my scope and dropping hex keys on the mirror.
Have seen advertised at OPT the 2 following artificial star collimators claiming that you can do the collimation without being hindered by atmopsheric conditions.
1.Astrozap
2. Hubble 5-star collimator

How accurate are they? I can afford to buy either, and for the price i just cant be bothered attempting to make one.

Any assistance and opinion much appreciated
