Small Comet 71P/Clark is seen near Antares and the Rho Ophiuchi region on May 26, 2017. At this time Comet 71P/Clark is a dim 11th magnitude object, barely visible in this photo. The comet is near one of the most beautiful regions of the sky - the Rho Ophiuchi complex. This photo was taken in my moderately light polluted back yard. Hopefully, i will find a clear night to photograph this encounter from a dark sky site.
The image was made of 62 fifteen second exposures taken with a Canon 70D and a Canon 200 mm f/2.8 lens. (ISO 1000, f/3.2). Stacking was done using Nebulosity. Tracking was done with an iOptron Sky Tracker.

This is an 18 shot panorama of the Milky Way rising above the derelict ruins of the Happy Valley Homestead near Williams, 1.5 hours south east of Perth in Western Australia.
The actual homestead, which is out of picture on the right (I took a separate image of that), has been restored somewhat but the rest of the property is feeling the passage of time. I placed a red headlamp in the smaller shed in the foreground.
The summer Milky Way over the Milk River Valley and sandstone formations of Writing-on-Stone Provincial park, in southern Alberta. On the horizon are the volcanic Sweetgrass Hills in Montana. The red tint at top is from an aurora active that night and the ground is partly illuminated by green auroral light from the north. The Summer Triangle stars are at top left. Sagittarius is on the horizon sinking into the low clouds at botton right which are illuminated by lights from Sweetgrass, Montana. Clouds and smoke from forest fires to the west cut down the transparency and clarity of the sky this night, especially toward the horizon.
This is a stack of 4 x 3-minute tracked exposures for the sky, and 4 x 5-minute untracked exposures for the ground, all with the 15mm Canon full-frame fish-eye and Canon 6D at ISO 1000, on the iOptron Sky-Tracker unit.
Jupiter from my backyard! Opposition (closest approach to Earth) was on May 8th but seeing was much better May 14th. One of Jupiter’s moons Io can be seen here casting a dark shadow as it transits across the planet.

Imagine that you could ignore all the stars in the sky and see only the nebulae on the milky way.
How would it be?
Well, I captured IC 2944 on March 31st, and removed the stars to put more emphasis on this incredible emission nebula.
The Running Chicken Nebula, which looks more like Jar Jar Binks (I read that in a reply from my Twitter and I loved it!) is an emission nebula very close to Eta Carina, but much more tenuous!
This capture was made between the 30th and the 31st of March, with the moon practically 100% iluminated!
This was only possible due to Optolong's L-Enhance filter.

NGC7635
Constelación en que se encuentra: Cassiopeia
Distancia: 1.400 años luz
De SkySafari:
#NGC7635, conocida como Nebulosa Burbuja fue descubierta en 1787 por Wilhelm Herschel. Es el resultado del viento estelar causado por la estrella SAO20575, de magnitud 8.7 que en la imagen aparece a la derecha dentro de la burbuja. La estrella es caliente, con temperatura de unos 36.000 grados C; el diámetro es 24 veces el del sol y su masa equivale a 49 masas solares.
La forma de la nebulosa es causada por el choque del viento estelar contra la nube de gas alrededor de la estrella, que también causa que brille. Se espera que SAO20575 termine como una supernova dentro de los próximos 20 millones de años.

This is a ten shot panorama of the North America Nebula and surrounding Cygnus region. It was processed with minimal stars, just the most prominent ones, and is a combination of RGB and H-Alpha images. The Ha shots were taken using a screw on filter which, while not being very narrowband filters at 20nm, are much easier to use than the typical clip in variety. This one was shot in Northam, 1.5 hours east of Perth in Western Australia.

This is a 23 shot panorama of the early season Milky Way rising above a dry Lake Norring, 2.5 hours south east of Perth in Western Australia. This lake is known for its numerous granite boulder outcrops, one of the largest is featured here. Though it's hard to tell the scale from this shot, it's about three times the height of an average person.
The 'redder' regions of this image were captured using a hydrogen alpha filter which isolates that particular wavelength of light, emitted by those nebulae.
A double cluster that is some 7,000 light-years away! though, this pair of open or galactic star clusters is an easy binocular target, a lovely star field in the northern constellation Perseus. Also visible to the unaided eye from dark sky areas. Unfortunately I cant see this from Romford due to the light pollution. The one clear night I had I decided to spend on this object as it fascinates me how two clusters appear to be close in a field of view, yet thousands miles and miles apart.

Happy New Year, Everyone!
On this very last day of 2022, I published a new article on my website that covers the recent update I made on my Askar FRA400 Imaging Platform - where I have moved to the new ZWO AM5 Harmonic mount!
This mount uses an entirely new technology to drive the telescope! Where most equatorial telescopes are driven by a classical worm gear arrangement, the AM5 uses Harmonic or Strain Wave Gear Technology for their mount.
This is a new mount on the market, but not the only one using Strain Wave Tech - you can expect to see more in the near future.
Strain Wave Technology is currently used extensively in Robotics and the Aerospace industry and is just coming to telescope mounts now!
This article covers why I moved from my previous mount, explores the Wave Strain Drive technology that the AM5 uses, and covers my experience moving to this new technology.

It's only five more days until they come within 1/4 degree (one half moon width) in the sky, early in the morning of January 7, 2018: www.jeffsullivanphotography.com/blog/2017/12/30/jupiter-m...
This was shot early this morning as Mars and Jupiter were rising on the eastern horizon.
This time-lapse sequence I took of Mars and Jupiter rising on the morning of January 2 by the light of the "supermoon" will be licensed for use in a broadcast by a major European network. Hopefully there will be an online copy I can access and get a URL to.
This was captured from Topaz Lake on the California - Nevada border.

Amidst the rarefied beauty of celestial events, the Diamond Ring effect stands out as a fleeting, yet unforgettable moment. It heralds the beginning and conclusion of totality during a solar eclipse, a spectacle where the moon and the sun perform a celestial dance across the sky. This image captures that precise, breath-taking instant, frozen in time through the lens of a Canon EOS Ra camera, expertly paired with an EF200mm f/2.8L II USM lens and a 2x III extender. The result is a stunningly sharp focus at 400.0 mm, utilizing an aperture of ƒ/8, a fast shutter speed of 1/1000 to catch the ephemeral light, and an ISO setting of 200 for optimal clarity.
Positioned with precision, my setup included the iOptron SkyTracker, a tracking mount that compensates for the Earth's rotation, ensuring that the celestial bodies remained in sharp focus throughout the eclipse. This was not just about capturing light; it was about capturing a moment of astronomical significance, rendered with exquisite detail.
The orchestration of this shot was further enhanced by SET'n'C (Solar Eclipse Timer and Controller), an invaluable tool in the astrophotographer's arsenal. This software automated the photographic process, creating a sequence of exposures that perfectly captured the varying intensities of light throughout the eclipse's different phases. It was SET'n'C that ensured the timing was impeccable, capturing the Diamond Ring effect with precision—where the brilliance of the sun's corona peeks around the moon's edge, juxtaposed against the darkened sky, creating a spectacle reminiscent of a radiant diamond set against a dark band.
This photograph is more than an image; it's a celebration of the precision and beauty found in the cosmos, captured from a unique vantage point on Earth. It stands as a testament to the wonders of our universe, the capabilities of modern astrophotography, and the enduring allure of solar eclipses. Each element, from the choice of equipment to the application of technology like SET'n'C, was pivotal in bringing this awe-inspiring moment to light.
