Celestron Telescopes Collimation Specialty Eyepiece 1-1/4" 94182 Product Info
The Celestron Newtonian reflector collimating tool 94182 is a combination of a sight tube and a Cheshire tool in a single unit. It has the precisely centered sighting hole and crosshairs of a sight tube, plus the cutout in the side of the tube containing the very precise 45° angle reflecting surface of a Cheshire tool. As it is a combination tool, it is less expensive than buying a separate sight tube and Cheshire tool.
Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1 1/4" focusers or diagonals. Alignment is easy using the small opening on one end and thin cross hairs at the other end. Specialty Collimation Eyepiece is more accurate than the simple Collimation Tool.
Features of Celestron Telescopes Collimation Specialty Eyepiece 1 - 1/4 ":
was easy to use when i figured out that i had to remove the relay lens built into the focuser.then iwas able to re aline the optics with no problem. i am an itermediat observer
Pros: easy to use, quailty constructiony
Cons: instructions could be bet...
The tool fits very loosely in the focuser to begin with so I don't trust it's accuracy. The bottom is recessed to make the fit even looser and it needs to be pulled almost all the way out to use as a sight tube in my XT10, verdict- useless as a sight...
My 10" garage sale reflector has had a rough life. You can eyeball the collimation and get it pretty close. This gizmo will get it right on fast. Read the directions!
This is one of two collimation tool I have. I really like it. I stayed away from the lasers because of the cost and mixed reviews. This tool is easy to use and the instructions are actually understandable (not a bad translation)
Pros: Very easy to us...
