So simple, so essential !
The two simple sets of easy to handle knobs are an essential tool for aligning both the secondary and the primary mirrors of the very fast (f/4) Vixen R200SS. The knobs can be easily turned by hand, which is a real boon by night and/or during an obse...

Much needed accessory
After years of astrophotography, I got around to use one of these instead of using software to focus, and the results have been way cooler than I excepted.

Batinov Disc for a Celestron NexStar 8SE telescope
As soon as it arrived I was able to place it on the front of the telescope and begin to focus it. Focusing is very easy and if you line up the third line in the middle it is next to perfect.

one of the most useful,
one of the most useful, simplistic, and effective ways to teach people new to Newtonians how to collimate. I have bought several over the years just for that reason. The last two both went to newbies a bit intimated by the process and both immediatel...

Does the job, room for improvement
Purchased this to collimate my C8 edgehd and I'm very happy with it. Makes collimation much easier than having to deal with a real star (don't have to worry about tracking and atmospheric turbulence). My only complain is that I wish the bod...

10" Schmidt Cassegrain Bahtinov Mask
I had purchased a bahtinov mask for my 120 mm refractor, and it works GREAT. So well, in fact, that I decided to purchase the 10" mask for my SCT. I received the product in two days, tried it out, and it works GREAT on the SCT, too. Accurate foc...

Great Value, Great Performance
I needed an artificial start to collimate the focus on my refracture, and the Hubble artificial star did the trick. I really liked having five point sources simultaneously available so I could pick the proper brightness to suit the job. Great product...

I ordered two of these for my other scopes. Identical to the original that I already have. They have felt underlays to avoid marring the painted surfaces of your refractors. Excellent find and expediently delivered.
