Didn't take too long to get to me works perfectly thank you.
Excellent product and a must for people using a SCT for astrophotography. Place your telescope on your mount or a table and setup the astrozap artificial star on a tripod 100 ft away. No need to worry about clouds or tracking.
worked very well.Was able to collimate in mins ,in broad daylight.Excellent product.
Made collimation so much easier! No waiting for "perfect" sky conditions. I have an 8" SCT and so I set up Astrozap about 150 feet away. Since the scope was horizontal it was a piece of cake to view the "artificial star" and to turn the adjustment screws on the front of the scope. Took less than 10 minutes to get the collimation perfect! The only minor complaint I have is that the battery compartment lacks foam backing, so the batteries come loose easily - I just put a packing peanut in there and that works fine. All in all Astrozap works great and is well worth the cost.
Still learning to use it. So far so good.
I used this on my Celestron Nexstar 8SE. The image is bright and stable and circles were very easy to see. I like that the unit accommodates a tripod. Using this indoors confirmed that my scope was not in precise collimation and enabled me to work on it under very suitable conditions using a range of magnifications. The Airy disk was clearly visible inside and outside focus so I was able to really dial things in. There is no way in my opinion that I could have achieved the same results using any other method.
