I am still experimenting with the Star Analyser 100. The Trapezium with a WO Zenithstar 103 and Player One Neptune camera. Pixinsight for processing.
The area around Sadr in Cygnus. Five exposures of 4 minutes processed with Pixinsight and Photoshop. WO Redcat, Bortle 9 sky near LAX.
Several hours worth of exposure of the Sadr region from bortle 2 skies Florida. The humidity was intense. One of the most fond memories i hold with astrophotography.
This was an eye opening shot for me. It made me realize just how much is out there. If you start a star gazing hobby, you'll never run out of things to see.

I took this shot in order to register the myriad of Milky Ways' stars at the Cygnus constellation. It's also possible to see Delphinus, Sagitta, Equus and parts of Lyra, Cygnus itself and Pegasus constellations.

This is the brightest globular cluster in the northern hemisphere, so bright that it is visible even to the naked eye.
About 23 thousand light years away from us, it contains several hundred thousand stars up to 14 billion years old, reaching a density of stars 500 times those we see in our sky.
Chosen at a time of bad weather and problems with my photographic setup, being very bright allowed me to achieve a good amount of data with relatively few shots, here the result with about 3 hours.

The Sadr Region is a gas rich area *visually* surrounding the star Sadr (arabic to "chest", referring to where it sits in the constellation Swan) and place of some of the most known nebulae, like the Crescent or Butterfly. Despite looking inside the nebula, Sadr is located at about 1,800 light years, whilst the nebula is at 5,000 light years; hence much closer to us. It is a F8 supergiant and its spectrum is one of the references to classify other stars.
This SHO rendition of the area is the first new photo in almost four months, after some equipment maintenance and lots, and lots of clouds. After so long, smoke from Canada's wildfires, Full Moon and winds of 30 km/h haven't deterred me…
Photo shot at Barcarena, Portugal (Bortle 8) on June 25th-30th of 2023.
Swan Constellation image (with a few sattelites) taken from Stellarium.
These three images are of the central region of the magnificent spiral galaxy M100, taken with three generations of the Hubble Space Telescope cameras that were sequentially swapped out aboard the telescope, and document the consistently improving capability of the observatory.
The image on the left was taken with the Wide Field/Planetary Camera 1 in 1993. The photo is blurry due to a manufacturing flaw (called spherical aberration) in Hubble's primary mirror. Celestial images could not be brought into a single focus. [Credit: NASA, ESA, and Judy Schmidt]
The middle image was taken in late 1993 with Wide Field/Planetary Camera 2 that was installed during the Dec. 2-13 space shuttle servicing mission (SM1, STS-61). The camera contained corrective optics to compensate for the mirror flaw, and so the galaxy snapped into sharp focus when photographed. [Credit: NASA, ESA, and J. DePasquale (STScI)]
The image on the right was taken with a newer instrument, Wide Field Camera 3, that was installed on Hubble during the space shuttle Servicing Mission 4 in May 2009. [Credit: NASA, ESA, and Judy Schmidt]
In celebration of the 25th anniversary of NASA's first space servicing mission to Hubble, these comparison photos of one of the telescope's first targets are being released today.
NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.

Sinking toward the horizon in the late twilight. Tonight I was a bit more prepared. The camera was mounted on an equatorial mount (heq5) so I was able to use an exposure of 3 minutes with no trailing. This also explains the odd horizon angle. Zoom was taped to avoid creep. Lots taken but this was the prettiest. :-) Needs to be viewed in Light box.

- www.kevin-palmer.com - This abandoned house with no roof is found on the American Prairie Reserve near the campground. As soon as I found it I knew I'd come back to shoot it at night. But I had to wait until 3AM when the moon had set. This area is in a 'black zone' on a light pollution map so the skies do not get any darker than this. Waves of yellowish-green airglow were very bright to the south.

Five minute exposure with a Canon R10 mirrorless and 50 mm Lens. From Chuchupate Trail near Frazier Park, CA.
Twenty minute exposure, 20 X 1 minute. Image captured from about 3 miles south of LAX. RASA 8 with QHY268 CMOS camera.
Located in constellation Orion and at about 6,500 light years from us, NGC 2174 is an emission nebula, rich in hydrogen and oxygen, with an apparent diameter slightly larger than the full moon. Within it, there is a loose star cluster, NGC 2175, with recently born stars. The stellar winds and radiation from these high energetic regions carve the nebula, yielding these beautiful structures.

The Zodiacal Light crosses paths with the Milky Way at Cinder Hills Overlook, Sunset Crater National Monument. The nearby open star cluster, M44, or Praesepe lies buried in the Zodiacal Light at lower left. The bright stars of Gemini—Castor and Pollux—lie to the left of the Zodiacal Light while Procyon lies to the right. Further up at top right, Betelgeuse shines a brilliant orange.

Taken from the deck at the airbnb I was staying at in Prescott, AZ. Before and after a thunder storm rolled through. 30 seconds each with a Canon T6i and 8mm lens.
Veil nebula and 52 Cygni. Ten exposures of 2.5 minutes, unguided. William Optics RedCat 51mm and Canon 60D.
This is my first attempt at a Hydrogen Alpha image of the sun, showing Active Region (AR) 2674 and 2679 (both to the left) and AR 2677 and 2678 (to the right). The image was taken using a QHY5-290C camera attached to a Lunt 50 THA solar scope. It is the result of 400 frames, stacked in Autostakkert 3 and processed using Registax6.
