Picture of Smart Phone Finderscope
This one is a simple smart phone finderscope attachment for  a telescope to assist one in quickly locating astronomical object.

(This is a quick instructable - I will edit it later but you get the gist of what we did)

We used it on Friday, 6th of Sept 2013  to locate Venus full day light - when the sun was well above the horizon.

The telescope is 100 mm Newtonian, home brewed by Pooja, who is looking at Venus. In the background are (from L to R) Smruti, Mayank, Hrishikesh, Jayshree  and Arunima.

I must say here that Pooja is slightly better than novice - she started observing just about 8 months ago.

At the time of posting this instructable we have not seen Uranus and Neptune but we are confident that it will be a 'damn' easy to do so.


All that is needed is

1. Smart Phone (of course) with sky map installed.
    I am using Samsung Galaxy with Google Sky Map app.

2. A cassette cover

3. A piece of wood - about the length and width of the cassette cover

4. I am using - ball and socket attachment with 20 TPI 1/4 inch bolt for camera.

5. 20 TPI 1/4 inch nut

Step 1: Nut to the wooden strip

A hole was drilled in the center of the wooden strip and the 20 TPI 1/4 inch bolt was fixed to it.

Oh, that's a good idea - the app is so much cheaper than one of those fancy mounts that find the stars for you (and they strike me as somehow cheating, anyway...).

Thanks and you are absolutely correct Kiteman -
In fact even this app I had considered as cheating.

For almost two years I was thinking - should I make or not to make - then yesterday I gave up on myself - it took me about an hour or so to get it going.
Have you entered it into the "Build my Lab" contest?

I wanted to but presently life is far too busy - with fair amount of admin work - I even lost my pro status given to me two years ago. In less then 3yrs I retire and then I will have my own world. LOL
All you need is a couple of clicks - follow the link I gave, then hit the blue button that says "Enter This Contest".

Nice work! Could this be done with a IPod and not a smart phone?

Wow, second edition of Universe by Kaufmann - you studied astronomy many years ago.
I don't think so - the app relies on GPS to fix its location relative to the sky, and iPods don't have GPS.
AlphaRomeo (author)  Kiteman1 year ago
Well Kiteman could be correct. I could use the the GPS on this phone to set my location. But one could set the lat / long of the location so if iPods do not have GPS but can track the sky then it should be possible to use it.

I purchased the phone exactly for this reason -- it was 10 USD phone.

Thanks Bill WW - I suppose one can use any such device - Kaufmann goes with me - the book is kind of reference manual for me - with notes here and there.
I smell crispy eyeballs.
