The telescopes are a collaboration project with the Harvard Center for Astrophysics and are labeled “Observing With NASA” because it is as if you had your OWN telescope and camera in a dark sky location. Their website is here:
They provide online training via YouTube and also have downloadable PDFs to explain the same material.
|Jupiter: a little shaky|
I found the lectures easy to understand. In fact, I like it as a model for how such videos should go. I just finished a project where the subject matter experts (SMEs) did not want to be bothered, so they made videos for me to watch, and it was pretty much a waste of their time and mine. These talks were all excellent, even though the results were often disappointing.
On the one hand, this takes some finesse and I am still developing that. Like opening the nut on a threaded fastener without bruising a knuckle, finding the right balances for the scales requires more practice.
That being so, it remains that the unattended instruments are not always locked on their targets for whatever reasons. I requested images of Jupiter, Jupiter's moons, and our Moon. All of them had problems, the Jovians worst. Our Moon was not centered on both of my requests.

and Green did not come out so good.
The telescopes are 6-inch (152.4 mm) Maksutov designs with focal length 560 mm (therefore f/3.47) with 5.25-inch (133.3 mm) correctors and 1.875 (1-7/8) inch (47.6 mm) diagonal mirrors, or about 31% center field interference. The cameras are charged couple devices (CCD) Kodak KAF 1400 (1000 x 1400 resolution). They have two magnification modes for 1-degree and ½ degree field of view (FOV) with 5.0 or 2.5 arc-seconds per pixel respectively.

Many students have a deep interest in astronomy, but a limited opportunity to use telescopes to explore the heavens. The MicroObservatory Network of automated telescopes is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. The intuitive interface makes it easy for even 10-year-olds to take pictures. Telescopes can be remotely pointed and focused: filters, field of view, and exposure times can be changed easily. Images are archived at the website, along with sample challenges and a user bulletin board, all of which encourage collaboration among schools. Wide geographic separation of instruments provides access to distant night skies during local daytime. Since “first light” in 1995, we have learned much about remote troubleshooting, designing for unattended use, and for acquiring the kinds of images that students desire. This network can be scaled up from its present capability of 240,000 images each year to provide telescope access for all US students with an interest in astronomy.
