5 of 5 Great Product and Experience with Eyepiecesetc.com October 5, 2020
Reviewer: Mike Letkewicz from Waterloo, IA United States  
The product was shipped promptly after my order and arrived quickly. Don was incredibly gracious with his time for answering a few collimation questions I had. The product performed great and Don provided unmatched customer service. Thank you and I will be back again!

5 of 5 The one I should have got first July 7, 2020
Reviewer: Jack from Indio, CA United States  
I’ve had a few Cheshire combo tools, none of them actually were able to give the correct view I needed to collimate my telescope. This one did, I now have great collimation! I recommend this.

5 of 5 ASTROSYSTEMS LIGHT PIPE SIGHT TUBE/CHESHIRE August 16, 2019
Reviewer: Matthew Orsie from Hedgesville, WV United States  
Don... I got this primarily for the sightube. Was there any doc that was supposed to be included that perhaps talked about the Cheshire aspect of it?

5 of 5 What a neat tool April 9, 2019
Reviewer: Kevin W from Kansas City, MO  
Don has been recommending this sight tube/cheshire combo for years on the Cloudy Nights boards. I took the plunge and it works great. The official manual from AstroSystems is about 12 pages, but Don provided a great paraphrased guide on using it and I had my scope collimated in about 25 minutes. A bit more practice, some aftermarket knobs on my 8" newt, and I bet I can get that down to 5 minutes.

I suggest using it in the daytime and not indoors [or at night!] to ensure you can see your center marker on your primary, and see the crosshairs of the lightpipe. An overhead lightbulb might not be enough to see it.
