Homemade Collimation Eyepiece
Posted by Oriontaage on Wednesday, September 10, 2008 12:56 PM

Hi,

In case anyone is interested, I just fabricated a combination tube for collimation (combination Cheshire eyepiece and sight tube with crosshairs). A pretty simple little project that only required about an hour and some free scraps for materials, saving me about $45. I have posted some pictures and a link to where I found the instructions on my accessories page:

Hi,

 My website provider's server has been down for the last week. It just came back on-line today, but all the public directory files were wiped out. Hopefully they can restore the file structure, otherwise it will take me a few days to upload new files from my website backup. Please be patient and I will try to have it on-line ASAP.

Thanks for the interest in my site and I will update this post when its up and running again.

Hi,

 My website is reloaded and functioning again. I finally said goodbye to free webhosting, bought webspace at a better webhost, and purchased the domain name in my signature. There was just too much downtime and unreliable service at the freehosting sites-I guess you get what you pay for.

 All details on my homemade collimation eyepiece should be back on line at:

Oriontaage,

Saw your collimation eyepiece. Very good. Unfortunately I already bought a Cheshire at Scope City.

Wish I would have seen your DIY. Would have saved some bucks.
