    I live in Glendale Az, and part time in Sun City. I mostly like to do astrophotography. I use an C Mak90 and an Evolution 150 reflector. Hope to share here.

    Images are hard to come by this summer. My main scope Evolution 150 went down with a bad focuser and had to return OTA under warranty. Looks as if they sent back a new OTA but out of collimation. Little boy in the Pacific is not cooperating, very little rain but clouds and humidity every night. I ordered a artificial star today, the cheap plastic flashlight one, then i found a Vitchelo LED headlamp I had received as a b-day gift that I did not like. Hmmmm, I punched an 1mm hole in a piece of friction tape and placed it over the lens, I now have a great artificial star, three levels of magnitude plus twinkling, turn it on,turn it upside down and it sits on anything. I set it in a corner on a chair ,set up a scope in kitchen about 25' away. It worked. Now I have to learn how to collimate.

    Here is a method using a star. I always use a Cheshire collimating tool and I use a TAK collimator. Remember the steps, the focuser must be square to the lens, use a laser that is collimated to check the focuser. Laser mounted in the focuser must shoot directly through the center of the objective. Then collimate. Extreme short version.

    Thanks for method. I should have noted that the Evolution 150 is a reflector. My bad. Upon recheck with the artificial star the collimation appears very good, that is one side of focus is dead on and the other side of focus is just ever so slightly off, don't think I should twist any screws.
