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
yet.

thanks,

I have a "toy" telescope (Skywatcher infinity 76" which I thought would be
interesting to my grandchildren.

It will show the moon and the moons of Jupiter but it has no finder. I use
a tablet PC with a planetarium program as a finder by putting the tablet
against the front of the telescope and centring the target on the screen. I
admit this is using a £400 item as a finder for a £35 scope but just about
everyone has a tablet or smartphone anyway.
For photography you could probably make something like this:
