t Far left: The opening screen of Seestar's
app displays weather and observing information
as well as the device's current battery
level and the four observing modes. Scrolling
down brings suggestions of things to observe.
Near left: While shooting images of objects (in
this case the Bubble Nebula, NGC 7635, and
nearby open cluster M52), the total exposure
time is tallied at upper right, while a countdown
" clock " surrounding the red square at bottom
keeps tabs on each 10-second exposure that
will be added to the total.
p. 66) made by the French company
Vaonis, and Unistellar's eVscope (S&T:
Dec. 2020, p. 66). But the Seestar has
several notable differences. Foremost is
cost. At $499, the Seestar is currently
about $1,000 less expensive than the
lowest priced of the other three. It's
also very compact. And while a bit more
difficult to quantify, its images generally
exceed what even experienced astrophotographers
would expect from a 50-mm
f/5 telescope. That quality was certainly
helped by ZWO's experience making
high-quality astronomical cameras
and associated software for more than
a decade before introducing Seestar in
April 2023.
Setting up the Seestar is very easy.
Out of the box its internal battery was
charged to more than 80%, so only
a few minutes connected to an old
iPhone USB charger topped it off. The
free Seestar app is available for iOS and
Android devices. Simple instructions
got the Seestar connected via Wi-Fi to
my iPhone 11 Pro so I could complete
a one-time activation process. The only
caveat here is that the phone needs to
be connected to the Seestar and the
internet at the same time. In the house,
my phone uses its Wi-Fi to connect to
our home network and the internet.
With the phone's Wi-Fi now used for
the Seestar connection, I had to rely on
the phone's cellular-data connection to
tFor many of the brighter deep-sky objects
(think Messier list), the Seestar can create a
remarkably satisfying view with only a minute
or two of exposure, but the best image will always
come with longer exposures. These views
of the Dumbbell Nebula, M27, are reproduced
directly from the files saved on the author's
iPhone. The one at far left was saved after only
1 minute of exposure, while one at near left is
the result after 41 minutes.
