A friend just donated an Amazon Fire tablet to the school. This is the
latest, cheapest model ($49 I believe on Amazon). It seems to have a
built in 720p camera. Two questions:

1) Can I use it in front of the ep we use for our ETX-90, that being
Scopetronix 40mm and 14mm eyepieces?

2) What adapter would I need?

3) What sort of image scale could I expect on the screen?

This is the first time I've ever run across such a device (tablet), so
not very familiar with it, but if we can get it going to use as a basic
camera in front of the eyepiece, it would be the most convenient set up


Very cumbersome method. Why not just let people look through the eyepiece unless you plan on taking videos which except for the Moon would be a wasted exercise with an ETX 90?

Group enjoyment instead of standing in a queue?

Easiest solution. Large scale image and plugs right into a tablet, laptop, etc.
Might need a usb to mini-usb conversion cable.
