For the Celestron Nexstar interface, I plan to use a Raspberry Pi with the camera. I will mostly be following the hardware used from this blog post; http://blog.raceconditions.net/nexstar-se-telescope-meet-raspberry-pi/
I will work on the web interface myself, and I will stream through a 3rd-party streaming service i.e. ustream, livestream, etc... in order to save bandwidth.
Amscope microscopes have c-mount adapters, and the Gopro will be much more interesting on the microscope for imaging.
I will also experiment with livestreaming of natural environments using binaural audio.
