My prototype cell phone telescope mount.
Posted 05 December 2012 - 02:05 PM
My phone doesnt fit the existing cell phone mounts properly due to its unique shape, so I designed one specifically for my phone as part of a school project. My professor has an xt6 and therefore liked my idea enough to have it printed out on one of our rapid prototyping machines.
I bought the proper bolts/nuts and it works quite well, but I left those pics on my home computer, so heres some of it before assembling and also what it looked like when I used some zip ties just to get a pic of it on my telescope. Since its made of plastic instead of metal, I built the shape of the bolt head into the body since that end of the phone needed to be propped up anyways.
Heres Jupiter and a moon(Europa?) from two nights ago-25 seconds of video, only stacked/edited with registax:

Your cell phone camera image looks ten times better than the direct-to-my-eye image I'm getting with my 10 inch f4.7 and the stock 11mm eyepiece. Was that picture taken with an eyepiece in place? If so which one?
BTW, nice job on the holder, too.

I wish I could try it on my 18mm meade 5k hd60, but the EP is way to large to fit. Id have to have a second clasp printed out.
Id like to get something to replace my 9mm plossl or maybe even go a with a slightly lower FL, but it needs to be a standard sized "body" to the EP. Would those of you familiar with ES eyepieces be able to recommend whether theyd be a good choice/fit?

This is the prototype correct?
Jupiter looks marvelous!

My other pics/videos arent quite as sharp, but were made using the same method as you. Find a good spot for the camera/phone, move the scope so Jupiter is at the beginning of its motion across the fov, then record as long as you can.
I try to use lower power in order to get the moons and such, but it ends up too bright even with my exposure all the way down and two ND filters.
Heres the video I used to make that pic:
If you check my other videos, youll see they arent quite as nice. I will add though that youtube added a shake reducing feature, so they were actually less smooth in their raw form.

Are the dimensions of your phone similar to a razrs? The place in the center of the main body where the bolt comes through is raised to conform to the weird curve on the back of the razr, it helps keep the camera surface flush with the mount, so it might just push your phone to an odd angle if it wasnt shaped similarly.

You might want to look into a patent as well, you have limited time to file one once you go public with the idea.

When I studied industrial design in college many moons ago we had to work with styrofoam to make some of our prototypes and cut and paste was actually cutting with a scissors and using real paste or rubber cement.

I think even more impressive than the technology is that theres an 11 year old boy as a student in my class. Hes real smart and has some cool ideas, but it can be a little weird when you snap to and realize youre discussing the flow of material through a mold with a child.

Do you know the material it is made from?
