Rho Ophiuchi cloud complex over Mt. Haeckel and nearby peaks by Dheera Venkatraman

This is the Rho Ophiuchi cloud complex setting over Mt. Haeckel and other peaks in the vinicity of Sabrina Lake in California, as seen with a 100mm lens on a full frame camera. The cloud complex covers an angular area of 4.5 x 6.5 degrees. That's about 9 by 13 full moons, which is huge, but it's difficult to see these gas and dust clouds with the naked eye. You can, however, clearly make out the star formation to the right of the Milky Way in summer, and if you grab a pair of binoculars you might be able to make out a little of these faint clouds!

This image used about 2 hours of stacked and tracked data to de-noise a single reference image. (I had pre-calculated that this star formation would set over these mountains, tracked and exposed the sky until it set to the position I wanted, and then turned the tracker off and continued to take exposures of the ground. I then stacked all the images with respect to the reference image, i.e. the last image before the tracker was turned off. The result is a low noise, detailed version of that noisy reference image.)

I'm doing an entire series of deep sky objects taken together with landscapes ("deepscapes") to show their visual sizes. Follow me on Instagram for more!

Milky Way over volcanic fissures by Dheera Venkatraman

Milky Way galactic core over volcanic fissures in Mono, California. Taken in July 2020. Bright dot to the upper left is Jupiter. Rho Ophiuchi (previous submission above) can be seen to the right of the Milky Way. This image was taken with a 21mm lens on a full frame camera with the aid of a star tracker to acquire a lower noise image of the sky. A low noise, long exposure of the sky acquired with the tracker on, and a low noise long exposure of the foreground acquired with the tracker off were matched and blended into a high-noise reference image to denoise it.

Lunar and Solar Extremities 2020

This overlapped photo sequence presents the biggest and smallest Lunar and Solar disks in a year taken with the same telescope and camera. However the bottom right part of the image was taken in 2021 as last January there were no spots on the surface of the Sun but today (on the day of the perihelium) sunspot #2794 is still visible at the edge of the disk.

M42 - The Magnificent Orion Nebula

LRGB Composition from Imagna's Valley (Alps - Italy)

The Jellyfish nebula (IC443) is the result of an extremely energetic supernova that occurred in the middle of a dense cloud of intergalactic gas. Blast waves from the supernova explosion created concentric shell structures roughly 70 light years across. To give you a sense of the incredible size of this explosion, 70 light years is roughly 4 million times larger than the distance Earth is from our Sun.

The Great Conjunction of 2020 - The waltz of Jupiter & Saturn
All of us waited for the Great Conjunction with bated breath, and the celestial spectacle took our breath away in December 2020. Having had an anxious eye on the gas giants as they came together in our skies, I had to take advantage of the few clear nights last month. Here, I've put together images from the (partly) clear evenings here, in Singapore, to show Jupiter and Saturn together in 9 stages, Jupiter & Saturn appearing closer from 11 Dec, closest on 21 Dec, and then moving away from each other.

EXIF details:

Takahashi FS-60Q 60mm refractor, f/10, Canon EOS R, ISO 1600, 0.5-2.0 seconds (depending on sky conditions for each image).

Hi,
I would like to submit my IC2118 image, that I've taken from Lebanon, around mid December 2020.

Title: The Witch Head Nebula - An Ancient Relic
Location: Aaqoura, Lebanon
Description: The Witch Head nebula is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel. It lies in the Orion constellation, about 900 light-years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color.

Just back from the (rainy!) eclipse in Chile, I drove to southern France to immortalize the historical conjunction of Jupiter and Saturn on December 22.

I tried to reproduce the vision I had of the two planets (including the Great Red Spot of Jupiter) and the four galilean satellites in a dark blue sky at sunset through the eyepiece of the CFF200 8" apo refractor.

6 YEARS SOLARGRAPHS

here is a photo montage of 6 solargraphs over 6 years, from equinox to winter solstice to see the course of the sun in the sky from the same place over 6 years.
each photo is a 3 months exposure.
Can with photo paper. At the end, i make a photo of the photo paper with the ghost image and work it on photoshop.
It's very interesting to see the difference of sunshine.

A pierced California Nebula, NGC 1499

While editing this image I saw a bright trail in one of the shots. It might be a meteorite or maybe a satellite which caught the sun while rotating. Whatever it was, I think it adds some scale to this immensely large nebula, so I edited it back in after stacking the frames.

I hope you like it!

Wow, dheera, I absolutely love that "looming color bomb" hanging over Mt. Haeckel! It looks absolutely truly amazing! And it's fantastic to see how large this familiar cosmic "nebula-scape" is compared with Earthly sights.

Thanks for this unforgettable view!

Travelling at 27,500km/h, the International Space Station flies roughly 800km above the Galley Head Lighthouse on Ireland's south coast in this 30-second exposure captured after dark on September 19, 2020. At the time this photograph was taken, the space station was occupied by the three-person Expedition 63 crew consisting of commander Chris Cassidy, and flight engineers Anatoly Ivanishin and Ivan Vagner.

Planets Jupiter and Saturn are also visible shining bright over the Atlantic Ocean.

Galley Head Lighthouse is located just a short drive from the town of Clonakilty in west Cork, and was built in 1875 during the heyday of lighthouse building in Ireland. When Galley Head was first constructed, it was the most powerful lighthouse light in the world.

"Star Wars"

180 degrees panorama multiexposure stitch, final size is: 8052 x 4026 px Captured with Sony A7s (land) and Canon 6d astromod (sky) + Sigma 14mm f1.8

Did you recognize him? Yes, the set of the movie Star Wars is the location of this 180°panoramic view of the Milky Way in winter!
Once the sunset was over, the Milky Way began to shine on the sky of this theatre of scenes that have written the history of cinema. Once I found the central antenna, the composition began to form in my mind, automatically.
A key element in the center, clean side exits, the galactic arch in all its splendor.
10 Iso shots 5000 f2.8 30 seconds to get the total overview of the scene.
A second Astro Tracked pano to complete a unique image, which reminds me of an extraordinary moment of Photography.

I don't think you can communicate the emotion of taking pictures at night inside a glacier, with fever, during a week of a solo trip sleeping in a car and looking for new spots in Iceland.
I have to say that this was one of the most extreme pictures I took, and this gave me so much awareness of my limits, I took home one night of aurora in the glacier, I waited three days for her, in the end, she arrived and I captured her in this 360° panorama.
