Here is 47 Tucanae, AKA NGC 104 from some time I booked on a telescope in Chile. It was harder than I thought it would be to process. This is a total of 1 hour and 40 minutes of exposure after I tossed 30 minutes of L due to 300s subs absolutely destroying the core of this. I wish I had done 2x more of R, G, and B rather than the 6x L. Still, it's a really cool looking glob!

Image Description and Details : Two popular long focal length targets, the Iris Nebula and the Ghost Nebula, share a field of chocolate colored dust in the constellation Cepheus. This 2 degree FOV captures both with plenty of room for the surrounding dark nebulae.

Captured over 4 nights in Goldendale Washington from Goldendale Sky Village and Sky View Acres. Both sites are Bortle 2.

The Horsehead is one of the most famous nebulae on the sky. The horse-head feature is dark because it is really an opaque dust cloud that lies in front of the bright emission nebula. Like clouds in Earth's atmosphere, this cosmic cloud has assumed a recognizable shape by chance. After many thousands of years, the internal motions of the cloud will surely alter its appearance. The emission nebula's color is caused by electrons recombining with protons to form hydrogen atoms. On the image left is the Flame Nebula that also contains filaments of dark dust. Just to the lower left of the Horsehead nebula is a blueish reflection nebulae that preferentially reflects the blue light from nearby stars.

WR 134 is a Wolf-Rayet star in Cygnus which is around 6,000 light years distant. It shines at 400,000 times the luminosity of the sun. Intense radiation and stellar winds have created a bubble of gas around the star. In this image the bubble is seen in blue/green doubly ionized oxygen (OIII) light. A large amount of hydrogen (HII) emission is also displayed as the red areas. The star responsible for this is near the center of the bubble and is whiteish. The image was taken with my #Stellarvue SVX 152T refractor and #zwoasi 6200 camera through RGB and HII/OIII filters. The image combines a bit over 47 hours of exposure time. Automation was controlled with a #primalucelab Eagle 4 pro and Voyager Astrophotography Automation software. The image is cropped and rotated for a pleasing view.

The Cave Nebula lies in the constellation Cepheus about 2,400 light years away, pretty close in cosmic terms. The “cave” has a bright rim ionized by the hot blue-white stars in the vicinity. The main “cave” structure is 10 light years across and is catalogued as Sharpless 155 (Sh2-155) and also as Caldwell 9 (the Caldwell catalogue was compiled by Sir Patrick Moore, and named for his mother’s maiden name). Near the lower left corner of the image is a blue reflection nebula, vdB 155. The Cave Nebula region makes a nice natural colour image, highlighting red emission nebula, blue reflection nebulae, dark nebulae and many colourful stars. I’ve also imaged the Cave Nebula before at higher resolution; that image was publishedin the April 2016 issue of Sky and Telescope.

The Belt of Orion or the Belt of Orion is an asterism in the constellation Orion. It contains three bright stars Alnitak, Alnilam and Mintaka.

The Orion Belt is easy to find in the night sky, as it is located on the celestial equator and is part of one of the most prominent stellar patterns in the northern sky, the hourglass-shaped constellation Orion. The asterism and constellation are visible in the northern latitudes from November to February.

This is an image made with an Epsilon 180 ed telescope, on an Atlas mount, Orion, PHP guidance system and a Canon EOS Ra camera.

Data acquisition is 120 images of 60 seconds, plus Bias, Darks and Flats.

mage Description and Details : I present to you an exotic object that was initially discovered as a planetary nebula but was requalified as a supernova afterglow that occurred over 7,500 years ago.
Located about 10,000 light years from home towards the Cassiopeia constellation, these are the filamentary remnants of a supernova that have a shell shape, part of which is doubly ionized oxygen (in blue) while the rest (in red) is essentially ionized hydrogen.

Well, a first version has already been made with the IFN (Integrated Flux Nebula) processing, clouds of cosmic dust located between the galaxies, specifically this is intergalactic dust that in the background give a somewhat dirty appearance to the image, but they are that, cosmic dust from space, composed of particles smaller than 100 µm.

Image Description and Details : Perseids Meteor Shower is probably the most beautiful of all, because of the Milky Way aligning in south-west direction during this time of the year. This is exactly opposite to the radiant point of these meteors (Perseus Constellation) which is in the north-east sky, and hence the opportunity to see meteors flying over the Milky Way's galactic center! This is a stack of images collected over the nights of August 11th and 12th at Joshua Tree National Park. The lone Joshua Tree in front of the park's Jumbo Rocks area gave me a gorgeous foreground, thanks to Google Maps and an hour of scouting. Although my camera captured only 14 meteors along with a huge Fireball, we could see many more meteors outside the lens' field of view with our naked eyes and every single meteor had people shouting in joy.
The past few months and years have clearly shown the devastating effects of climate change and to add to the long list of consequences, the California wildfires from Climate Change also meant smoky skies for most of the northern part. Clear skies may not be on top of the priority list, but this would mean we can no longer preserve the natural beauty of night sky, thereby affecting the millions of animals and plants that need clear skies to survive at night. It's imperative that we all act immediately with small steps and preserve what nature has created for us having endured a multitude of external factors. Dedicating this post to the brave firefighters @calfire who have been battling to contain one of the biggest wildfires in recent history.

Image description 

Ngc3511 is an intermediate spiral galaxy located 45,000,000 light-years away in the southern constellation of Crater. Appearing at lower-right, it was discovered in 1786 by William Herschel, and is about 70,000 light-years across. At upper-left is the face-on SBc spiral, NGC 3513, gravitationally related to 3511.
Many thanks to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data from Observatorio El Sauce, Chile. I dedicate this image to fellow astrophotographer and friend, Rogelio Bernal Andreo, on the passing of his beloved wife, Ariana. May she go among the imperishable stars!

Image Description and Details :

NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, the elephant trunks.

Image Description and Details :

The image is of the Hanle Monastery under Bortle 1 skies and the Perseids. Hanle monastery is a 17th century gompa of the Drupka lineage of the kagyu school of Tibetan Buddhism located in the Hanle valley of Leh District, Ladakh, India. Hanle lies at an altitude of about 14500ft and is also home to the Indian Astronomical Observatory . The location of the monastery and the observatory is highly sensitive due to its proximity to the disputed Chinese border and access is restricted to a very few. Image was taken on the nights of 10 and 11-Aug-21. A blue hour foreground was first shot and then when the quadrant rose, 20 images of the night sky were stacked with the meteors blended in.
