Good evening fellow astro buffs!
If you are involved in doing star parties or any astro education, you have I'm sure been asked about magnification.
Sure you can do the math and keep all the numbers for all the combinations of your scopes and eyepieces in your head... or you can purchase an iOS app.
I recently purchased Astro Aid ($2.99) to solve all these mysteries and was pleasantly surprised at the quality of the User Interface as well as the library of equipment and targets.
Here is the itunes link ...https://itunes.apple.com/us/app/astroaid/id541448395?ls=1&mt=8
Of the 30 plus astro app's that I have, this is one of the top 10 for usefulness.
I especially like the fact that you can select virtually any imaging camera and have it show you the field of view with your selected target ....
Also it will display the field of view for any eyepiece / telescope combination.
This is a really cool app for quickly and easily illustrating what you will be seeing or imaging.
Attached are to screen shots showing all the detailed information with my 10" RCOS and FLI ML8300.
Really cool app....
What's in your iPad ?
