Farpoint Bahtinov Focus Mask for Celestron 11" SCT # FP412
Bahtinov mask for 6" Nexstar SE
Well made. Works as advertised. Had to make some small shims, however, to center mask perfectly. Otherwise, works great.

Howie Glatter 650nm Standard Brightness Red Laser Collimator - 1.25"
Doesn't come with concentric circle attachment
Even though the description states: "The collimators are supplied with a removable plastic aperture stop having a knife-edge, 1mm pin hole and a screen front. The beam of all red diode lasers is blurry-edged and has an elliptical cross-section. ...

Farpoint 1.25" Reflective Cheshire Collimator

Purchased this to learn to collimate my 10" reflector. Looking at the web page, it's not clear that you have to remove your primary mirror to put their target stickers in place. They then talk about using their Farpoint Laser Collimator (in...

Rigel Systems Aline 1.25" Telescope Alignment Eyepiece / Collimation Cap
Works particularly well
After spending some time comparing this tool to others in my tool box, I've really come to appreciate the fact that this tool "self centers" because of the way it press-fits into the focuser. This makes the tool's placement extrem...

Rigel Systems Aline 1.25" Telescope Alignment Eyepiece / Collimation Cap
Aline collimation cap
These caps are almost impossible to find, but they are a quick, easy, inexpensive device for collimating Newtonian reflectors. Works well. Very satisfied with Agena's service and prices.

Bob's Knobs for Celestron C6 f/10 Secondary with Metric Collimation Screw Threads # C6
Simple and effective
All SCTs should have these... they make colimation much easier without needing to be on the front of the scope. You see the changes immediately as you turn the knob.

Farpoint Carey Focus Mask for Telescopes With Dew Shield or Front End Diameter from...
Gets the job done

GSO 1.25" Newtonian Deluxe Laser Collimator III
Must Have for Newtonian
This is a good collimation tool for the price. It is very easy to use and a must for good images if you have a f/4 - f/6 Newtonian.

Rigel Systems Aline 1.25" Telescope Alignment Eyepiece / Collimation Cap

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