There has been a recent paper published on the Acta
Astronautica website about a telescope under development, that will soon be
available to the public (depending on when you read this, it might already be
available). It is specifically designed
to facilitate viewing from light polluted skies, a problem that exists for many
observers. This is called the eVscope.
The telescope is a Newtonian (reflector), with a 4.5 in
(114.5 cm) aperture, so it isn’t really all that large, in terms of light
gathering power. However, it has a low-light
CMOS sensor at the prime focus, essentially an electronic camera. That sensor captures multiple frames of an
image, using exposure times of between 1 millisecond and 4 seconds. An onboard computer then stacks and processes
these frames - the usual processing that you might do with an astrophotography program
is done automatically to improve the image. This all produces an image that is projected
through the electronics eyepiece. Though
the setup is designed to mimic dark sky viewing, the data can also be accessed
by the user in TIFF format, so that additional processing and analysis can be
performed.
The telescope also
contains an algorithm to find and identify stars and deep sky objects, based on
a large internal map in memory. In that
sense, it is a goto telescope with embedded data that can also can display the
relevant information right on the viewing screen (i.e. through the eyepiece) as
shown in the photo from the paper.
So, it is intended to make it easy to find and to identify
objects, two obstacles to observing that get in the way of many observers
enjoyment. Though learning how to
star-hop and such can be its own reward, it can be quite tedious,
time-consuming and frustrating for anyone who is not quite dedicated; this helps users to spend more time observing and less time searching.
The
objects in the telescopes database include:
- Planets and the moon
- Messier objects (all 110)
- Thousands of NGC objects (at least 7840 of them)
- Thousands of smaller solar system objects, such as asteroids and dwarf planets.
The ease of use of the telescope, along with its embedded
data handling should enable the data from each scope to be used for scientific
work, yielding a sort of citizen science crowd-sourcing of astronomic
observations. That could enhance the
study of transient events as well as helping keep a global watch on possibly
dangerous bodies that could wreak havoc on the Earth due to a collision.
The paper gives some examples of the eVscope’s scientific
possibilities, including light curves from occultations, such as this
occultation of a 13th magnitude star by Pluto.
The eVscope is supposed to be available to the public soon,
by early 2020. It won’t be cheap – their
website is currently advertising $2999 U.S., with a delivery data of summer
2020, according to this screenshot. If the reviews of the product hold
up, it looks very tempting.

And if $3000 is a
bit too much, here are a couple of short science fiction stories that you might
want to try for only 99 cents.
The Zoo Hypothesis or The News of the World: A Science Fiction Story
In the field known as Astrobiology,
there is a research program called SETI, The Search for Extraterrestrial
Intelligence. At the heart of SETI,
there is a mystery known as The Great Silence, or The Fermi Paradox, named after
the famous physicist Enrico Fermi. Essentially,
he asked “If they exist, where are they?”.
Some quite cogent arguments maintain
that if there was extraterrestrial intelligence, they should have visited the
Earth by now. This story, a bit tongue in cheek, gives a fictional account of
one explanation for The Great Silence, known as The Zoo Hypothesis. Are we a protected species, in a Cosmic
Zoo? If so, how did this come
about? Read on, for one possible
solution to The Fermi Paradox.
The short story is about 6500 words,
or about half an hour at typical reading speeds.

The Magnetic Anomaly: A Science Fiction Story
“A geophysical crew went into the Canadian north. There were
some regrettable accidents among a few ex-military who had become geophysical
contractors after their service in the forces. A young man and young woman went
temporarily mad from the stress of seeing that. They imagined things, terrible
things. But both are known to have vivid imaginations; we have childhood
records to verify that. It was all very sad. That’s the official story.”
