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. https://www.space.com/cygnus-constellation.html https://en.wikipedia.org/wiki/Cygnus_(constellation) https://www.constellation-guide.com/constellation-list/cygnus-constellation/ edit: This is the equivalent of 19 minutes of exposure.1 point

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.

Guiding Lights... 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. 1) Neptune: https://solarsystem.nasa.gov/planets/neptune/overview/ 2) Saturn: https://solarsystem.nasa.gov/planets/saturn/overview/ 3) Fomalhaut: https://earthsky.org/brightest-stars/solitary-fomalhaut-guards-the-southern-sky/1 point -

Scorpius with some Milk(y Way) on the side... 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.

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. https://earthsky.org/constellations/scorpius-heres-your-constellation/ https://www.constellation-guide.com/constellation-list/scorpius-constellation/ I hope to be able to post a version that is more centered on the constellation.1 point -

Yes. Set clarity to "0". That is what is slowing down your write times. Clarity adds a lot of overhead to the processing time.1 point
