Eyepiece Calculator

[pvaz]

I'm hopping this will get sticked so try and keep the thread clean please.

Well it was raining last night so I made an Eyepiece calculator. I was doing it for me but I decided to have a little extra work and make it user based.

Current functionality:

In the "My Gear" menu:

- You add all your telescopes and say for each one the FL, Aperture and focusers size (2", 1.25" or both if you have an adapter).

- Then you enter all your Barlows, for each one you identify the magnification and size and what EPs it can be used with (2", 1.25" or both)

- At last you enter all your eyepieces, define the focal lenght, AFOV and size.

Press the "Results" and "voila" all the possible combinations for each scope/barlow/EP will appear magicly with values for FOV, Mag and Exit Pupil. You can export to excel or pdf to store locally or login at any time to add a new Eyepiece/Barlow or Scope.

To create an account you just need an email and a password. (Name is optional) You can use bogus info if you want.

I attached 2 print screens of those 2 areas.

Hope you like it.

Just some notes:

- All measures for Aperture and Focal Length should be entered in mm (If you have an 8" scope enter 200 for aperture).

- Measure for the Eyepiece AFOV is in degrees as usual.

PS-> If you find typing errors or bugs pm me. (English is not my native language and I do some typos.)

Fantastic idea! Is this likely to become a standalone prog?

Thanks!

Ivor.

Hmm.... one problem so far. I'm trying to change the FOV value of an eyepiece, but it isn't updating.

Seams the async ajax service crashed on the server.

I restarted it and tested on IE, Firefox and Chrome. Please try again.

Note: The export to PDF button is unavailable for now since the server admin blocks me from using some system functions I need. I'll have to figure another way to do it.

The export to Excel function works fine.

[Takahashi]

Yep, that fixed it. Thanks!

Can be. I'm very busy with a project right now and will be 'till late February. Then I plan to go 1 week to the Caribbeans, to get my head straight and operational with a "Rum based drinks" intensive diet . After that I'll take a couple of weeks to learn the latest technology in .NET based applications, witch is Silverlight 3. (may be on version 4 by the time since Microsoft never stops giving us programmers stuff to study.)

Silverlight applications can work as both a standalone or a web application and can run on any given Operating System, provided Microsoft already haves a pluggin in place for that OS.

This small application may be something of interest for my 1st steps onto the Silverlight world. (Though my wife already "commissioned" a database app for her architecture projects and items used on them...)

I'll keep you guys posted.
