There are many types of interesting and overlapping nebulae in this region including many HII regions catalogued by Dickel, Wendker, and Bieritz, as well as the giant supernova remnant known as G 82.2+5.3 which takes up the left side of the image. Because it is so faint; 20 hours of exposure via the OIII filter here barely shows it.

DWB 111, also known as the Propeller Nebula (in the lower right quadrant) is a hydrogen-alpha emission nebula. The propeller shape is actually a small portion of a much larger emission nebula, which can be seen as red hydrogen-alpha background nebulosity throughout the image frame. The distance to the nebula is not known.
​
PM1-320 is a small planetary nebula, close to DWB 111 and seen here in the upper right quadrant.
It was discovered by Andrea Preite-Martinez in the 1980s.

North America Nebula

First image with my new setup. 45 shots at 300 seconds each.

The shoot was a test for an ASIAIR Plus review, using a Losmandy GM811G Equatorial Mount, William Optics GT81 Telescope, ZWO ASI2600MC Cooled Color Camera, ZWO ASI120MM Mini Camera, ZWO 30mm Mini Guide Scope, ZWO EAF - Electronic Automatic Focuser, and ZWO EFW - Electronic Filter Wheel. Using both an Android phone and a sideloaded Chromebook.

THE GLOBULAR CLUSTER - MESSIER M69


Discovered by astronomer Charles Messier, who added it to his catalog on August 31, 1780, along with Messier 70.
It is one of the weakest globular clusters in Messier's catalogue, with low metallicity. It can be seen as a small mist in binoculars.
However, due to its southern location, it is a difficult object to be seen by observers in the Northern Hemisphere.

NGC 7678 in Pegasus. KG Observatory, Julian CA.

NGC 7678, with one particularly prominent arm, is located approximately 164 million light-years away in the constellation of Pegasus (the Winged Horse). With a diameter of around 115,000 light-years, this bright spiral galaxy is a similar size to our own galaxy. It was discovered in 1784 by William Herschel.

The galaxy's heavy arm stems from an increased density of stars' gas in the area. Formations of spiral galaxies may be influenced by magnetic fields, and variations in the intensity and flow of those fields could alter the distribution of star-forming gases. The heavier arm was likely a recipient of more gas earlier in the lifespan of the galaxy, allowing more stars to form.

NGC 7678 is among the 338 galaxies presented in the Atlas of Peculiar Galaxies, which organizes peculiar galaxies according to their unusual features. Cataloged there as Arp 28, this galaxy is listed together with six others in the group “spiral galaxies with one heavy arm.”

I have (unfortunately?) almost given up on commenting on the images in this forum. But I have to say that I love this picture of NGC 7678. It is such a fascinating galaxy, it is almost never photographed, and your image is so fine!

Thank you!

Panoramic photograph taken in the Fortaleza Canyon, Cambará do Sul/Brazil.
To make this panorama, two Panoramic images were used, one of the sky taken in my first Workshop on site in 2019 and the second in the last Workshop, in Aug/21.
In 2019 the sky was perfect but the Fortaleza Canyon was very foggy. In Aug/21 the sky was a little cloudy but the visibility of the Canyon was perfect. In this image we can see the union of these two moments.
The two panoramas used were taken at night, and the second one, used for the terrain, there was a moon in the sky, which helped to obtain an adequate exposure for the terrain even at 9 pm.
The Fortaleza Canyon is a giant 7km long and 900 meters deep in some stretches. Being in a place like this is an amazing experience, especially at night and under the stars.

NGC 4676 from Hubble by William Ostling, on Flickr

These two mighty galaxies are pulling each other apart. Known as “The Mice” because they have such long tails, each spiral galaxy has likely already passed through the other. They will probably collide again and again until they coalesce. The long tails are created by the relative difference between gravitational pulls on the near and far parts of each galaxy. Because the distances are so large, the cosmic interaction takes place in slow motion — over hundreds of millions of years. NGC 4676 lies about 300 million light-years away toward the constellation of Coma Berenices and are likely members of the Coma Cluster of Galaxies. The above picture was taken with the Hubble Space Telescope’s Advanced Camera for Surveys which is more sensitive and images a larger field than previous Hubble cameras. The camera’s increased sensitivity has imaged, serendipitously, galaxies far in the distance scattered about the frame.

The Ruins of Nógrád Castle
Copyright: György Soponyai

Castle of Nógrád is one of the oldest castle in Hungary, the first hillfort was built in the age of Barbarian Invasions. In the 1400s the fortress was restored and a four-level renaissance castle was also added/built. Between 1544-1594 and from 1663 it was occupied by the Turks however in 1685 a thunderstroke ignited the gunpowder stored in the high tower and the huge explosion completely demolished the whole castle. Since then only the ruins are guarding the 286-meter-high hill.

Moon Phases from 2021 August 15th to September 13th
The photos of the moon were taken from August 15th, age of moon of 7.2, through September 10th, age of moon of 3.6. On September 11th, typhoon #14 Chanthu began to hit Taiwan and interrupted the progress. A friend Bob in Phoenix, Arizona agreed to complete the last three moon phase photographs that ended on September 13th, age of moon of 6.7. Through the cooperation of Taiwan and USA, the month-long moon phases documentation finally completes. In order to reduce the refraction effect by the atmosphere, the photo sessions were conducted when the moon was at higher viewing angles. But due to the weather condition and change of the moon positions, occasionally they were taken at lower angles during moonrise or moonset. As a result, a few photos are not as sharp as desired.
The phase angle production of every moon photo was referenced to the 2021 moon phases data on NASA’s website. Individual photos were adjusted so that the viewing angles are identical to the simulated moon phases on the website.

A very faint but very large squid-like nebula is visible in planet Earth's sky -- but inside a still larger bat. The Giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula are in the left region of this image.

Barnard 150, also known as Seahorse Nebula, is a dark molecular cloud of dust, located in the center of the image.

Fireworks galaxy (NGC 6946 is a medium-sized), face-on spiral galaxy about 22 million light years away from Earth, located on far right.

I have postponed this for a long time due to the numerous framing orientations of the subs, hence the square crop.
Turns out to be great!

The H-Alpha stack was insanely beautiful and vivid, makes you think on the great astrophotography targets they have there O_o

The Heart in the Swan - starless by jason.doyle.sr, on Flickr

Directly overhead in late Summer and early Fall, the constellation of Cygnus the Swan contains a ton of bright nebulosity and dark dust lanes.
This photo captures the small, bright blue reflection nebulae named NGC 6914, with vast clouds of emission nebulae and dust surrounding them.
The main structure here doesn't seem to have an official name, but I thought it looked like a heart 🤎
Maybe it should be the Heart of the Swan?

I added a starless and a close up version, too
