Just playing around with star trails.  XT5, 12mm Samyang, stacked about an hour of 40 second exposures.  A campfire illuminated the canopy.

Milky Way in May...

This is equivalent to a just-a-touch-over 15 minutes exposure.

Milky Way season is underway, and locally, the Milky Way is starting to rotate from landscape mode to portrait mode (it should be fully rotated to vertical in about a month, give or take a few days). On the right side, in this image, the Scorpius Constellation is rising. Antares is the big yellow-red star in Scorpius.

I hope to be able to post a version that is more centered on the constellation.

This image is also the equivalent of just over 15 minutes exposure. A lot of passing clouds got into this one, but they opened up for the constellation. More Antares info:

July's full moon is perigee-syzygy, a supermoon.

Milky Way in July...

Smoke from various wildfires has cleared out a bit. Earth's trek around the Sun (an ellipse) has tilted a bit from earlier, making the Milky Way seem like it rises vertically, a disc in the night sky. This is equivalent to 2 and 1/2 minutes exposure time.

This is the equivalent of a 40 second exposure.

Knowing where you are while traveling in the Northern Hemisphere these days is fairly easy if you have the comforts modern technology offers. GPS based maps rendered in nice colors on tablets and phones or standalone devices give you your location almost instantaneously.

It used to be though, one used a compass based map (or some other vague directions) and at night, the North Star. But if you were traveling in southern directions, lining the North Star with your route could be troublesome. Not to worry, there is a star called Fomalhaut ("The Lonely Star") that does the job almost as well as Polaris (the North Star) does.

Messier and Messier and Messier...

Smoke from wildfires has cleared some more. Locally, it is getting late in the season for seeing these nebulas, they are dropping closer and closer to the horizon this time of year, but they should be visible for a while yet, especially in the more southern latitudes.

This is the equivalent of just under 25 minutes of exposure.

Summer Swan...

Starting in late summer, say late August or early September, the Cygnus Constellation is directly overhead ("Just Look Up") for folks in the Northern Hemisphere. As is usually the case with constellations, there are differing cultural views and fanciful tales about things going on in the skies.

North America ...

NGC 7000 is the name / number / title given to a nebula in the Cygnus Constellation that actually does resemble most of North America, though I think the Canadian part gets short changed.

This nebula is pretty popular because it contains so many fascinating parts. Along the left side of "Mexico" is something called the Great Cygnus Wall, and over to the right of NGC 7000 is another popular nebula called the Pelican Nebula. Pelican Nebula is a little fainter, so it needs more exposure time to fill it in so it shows as much as the North America Nebula.

This is the equivalent of 80 minutes of exposure.

Back on this thread's Page 1, the posting for Messier Object M31 (The Andromeda Galaxy) has a wider view added.

[jerryy]

Also, back on Page 1, the wide-field view of Messier Object M45 (the Pleiades) has been replaced with a new version. The new, completely different version was photographed from a different location using a different lens and camera body.

Been a while, thought I'd check in.  First attempt at a Milky Way photo........when I could actually see it, lol.  

Assateague Island, MD in October.  Beautiful night on the bayside.

Back on Page 2 of this thread, there is a posting for NGC 896, the Fishhead Nebula, 'Ol Fishhead juts off from the beautiful Heart Nebula, IC 1805. On the other side of the Heart is IC 1831 (also attached to the Heart Nebula). IC 1831 is a faint Diffuse Nebula in Cassiopeia's Constellation. The brighter nebulas get more attention, but IC1831 has its own merits.

This is the exposure equivalent of 80 minutes, 25 seconds. The nebula in the lower right hand side is the Soul Nebula, IC 1848.
