Simple is sometimes best
Works well on my 10 inch Dobson. Paired with a Cheshire with sighting tube works well for collimating a reflector.

Great product
I bought this HoTech laser collimator to use on my XT8. Easy to follow instructions and spot on collimation. What more could you ask for. Highly recommended.

Review
Works as advertised. Did my scope in short amount of time. Easy to use. Gave it four stars because its not perfect, should include detailed instructions for collimation, but it is good.

Cleaned my CPC 800 corrector plate and mirror, so a complete removal. Put the corrector plate back on and it was completely out of collimation of course. Installed Bob's Knobs, and was collimated in just a few minutes. Worked so well I just orde...

Works Very Well
The mask works as advertised and helps me to focus when using my Canon T2i and 135mm lens. With the smaller FL lens, I use a higher than normal ISO (3200) and have the aperture wide open (F/2.8) and focus on a bright star. I don't bother shootin...

Great product.
Works as advertised. I own a cheaper laser collimator that would wiggle in the barrel. This Hotech collimator holds nice and firm giving a more accurate alignment. With the laser crosshair, aligning the mirrors is much easier. Worth the extra money t...

Works Well
Very economical tool that worked for collimating my Newtonian scope. Knowing what I know now I would recommend spending more for one that has variable brightness for the laser.

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.
