Hi everyone, now that Comet NEOWISE is in our evening sky, everyone
wants to try to see it, especially from a safe place like their home.
The comet, from an urban area, is extremely difficult if not impossible
to see with the unaided eye. Start looking about an hour after sunset.
Binoculars help once the sky darkens. It's hard to find through a
telescope, binoculars are better, unaided eye nearly impossible. So, to
set expectations, here are two images I took 2 nights ago from Duarte
Sports Park only a mile from our house. Lots of urban lights, but this
location put some distance between the viewers and the mountains. These
are taken with my cell phone so they will represent a better expectation
of what the urban comet hunter will see. It won't look like the images
from a dark sky or another part of the world, but it will be your very
own view!

JPL has an excellent easy to understand comet finding chart here :-)
Many media charts show other stars in Ursa Major (the nose and the paws
of the great bear) but those stars are not easy to see or familiar to
many, so kudos for a great chart JPL!

To help you figure where to look beneath the familiar dipper, here is my
favorite chart:
https://www.timeanddate.com/astronomy/measuring-the-sky-by-hand.html .
Use your outstretched hand and notice your thumb to pinkie span the
familiar Big Dipper asterism as shown on the chart. So, to see the comet
you need to look this same distance below the dipper! That's why you
have to get away from the mountains!
Finally, here are some additional charts that also show the dipper and
the comet's path from Earth and Sky

Sky and Telescope

For those asking where to go to see the comet, look for a place where
your NW horizon is not blocked by the mountains. The comet was 12
degrees above the horizon close to an hour after sunset last night. We
were able to see it (with difficulty and not naked eye) a block from our
home through a notch in the mountains. Use the dipper as your guide, can
you see lots of sky below the dipper? Closer to the beach. At some
elevation. You get the idea. :-) Let me know of your success, and you
have a little more than a week until first quarter moon will brighten
the sky more. Good luck! There is almost nothing more exciting that
seeing a comet, especially a public friendly, conveniently timed,
traveler that won't return for nearly 7,000 years! JPL's What's Up page
