Helpful astronomy app for iPad-iPod

[apaulo]

Hi techno buffs

Surfing the App Store, looking for iPad apps and I came across this app called. "Astro Aid" by iLanga.
The app will show you the FOV of your eyepiece, DSLR, CCD camera and guide cameras when viewing or imaging deep sky objects.
It has all the catalogs of Messier, NGC, IC and others.
You can list the telescopes by brand or you can customise your own specs.
There is a option of introducing barlows, focus reducers and flateners.
This app will cost you about $3.29, they seem to suffer from inflation too.
The only thing I not like about the app is the image of the DSO is in black and white.
Anyway have a look.
Regards Paul.

It's a good app. My main complaint is that the image/photos used to simulate the FOV are a max of 1 degree, so it's not great for wide view/low power
