An LRGB rendition of the NGC 5907 (Knife Edge Galaxy) and the Type II supernova SN 2026kid newly discovered by Yasuo Sano on Apr. 22. #Astrophotography

Supernova SN 2026kid in the Knife Edge Galaxy (NGC 5907) tonight through a Green filter. Current mag. is ~15.6 by a quick aperture photometry on the stack in Siril. Stay tuned for an LRGB image later. 8" F4 Newt + 585 Mono 47 x 60s G, 2026-04-26 21:37-22:29 EDT (UTC-4) #Astrophotography #SN2026kid

Just a little less than 4 hours of Ha on vdB 142, with a sensitive IMX585 mono camera, an 8-inch Newtonian and a decently fast focal ratio of F4. #Astrophotography

The Rosette Nebula (Caldwell 49) is always a majestic sight to behold - a bright patch of H II emission in Monoceros, next to the distinctive Orion stars. A collaboration of two ToupTek HOPE D60 + ATR2600C setups resulted in the following shot over just a few hours of clear skies. #Astrophotography

Simeis 147 (SNR G180.0-01.7), also known as the Spaghetti Nebula, is an expansive supernova remnant that spans the width of 6 Moons side by side on the border of Auriga and Taurus. I gave it spaghetti colours with a slight shift in the Ha hue. #Astronomy #Astrophotography

Live stacking enables us to quickly get an idea of what major structures will show on the final image. I use the "Folder Monitor Camera" in SharpCap, in which I can open the folder with NINA data and stack exposures up as they accumulate. It's only a matter of increasing SNR atp. #Astrophotography

A break in the clouds magically appeared above some parts of southern #Ontario around midnight, so I was able to catch a quick glimpse of the #Aurora in time! 😍

The California Nebula (NGC 1499) is a large, rich patch of emission in Perseus, its trapezoidal shape resembling the State of California. The Ha, SII and OIII components reveal beautifully in narrowband filters, and an OSC camera was used to compose the SHO image below. #Astronomy #Astrophotography

The Coathanger (Collinder 399) is an interestingly shaped asterism in Vulpecula. A binocular can be used to observe it visually. Here is my broadband photo of the asterism and its surroundings at ~1.2h of integration from last night. #Astronomy #Astrophotography

DeepSNR in action: Top is original data (24x180s UVIR, bottom-left is NXT applied at 0.7, bottom-right is DeepSNR applied at 0.7. #Astrophotography

Hello #CometLemmon, all the best on your journey! I captured the comet in this composite with a 40-year old vintage Minolta lens (MD 50mm f2). The foreground was shot at 17mm f1.8, all on a small MFT pocket camera. #Astronomy #Astrophotography

😎

Th weather is looking really promising (a bit chilly here though) for southern Ontario and other areas around the Great Lakes starting Sunday! Find a place with good visibility of the western horizon and go meet #CometLemmon due west after sunset!😃 #Astronomy

You can easily snap quick shots of #CometLemmon with the landscape now, through regular cameras or phones, as long as the weather cooperates. This was a 10s exposure last night at ISO400, taken with a M43 camera and 17 mm f/1.8 lens (FF equivalent of ~35 mm) near Lake Simcoe. #Astronomy

NGC7822 and Sh 2-170 are two emission regions in Cepheus, that form a shape similar to a question mark. Using two dual band filters (6 nm Ha-OIII and 7 nm SII-OIII) with an OSC camera, I was able to produce a colourful composite of the area in true SHO palette🙂 #Astronomy #Astrophotography

My attempt at #CometLemmon in the early hours of Oct. 14th. The comet is brightening and rushing towards closest approach to Earth (Oct. 21st). It's getting low in the morning sky, though it will pass into evening sky for convenient viewing soon. #Comet #C2025A6 #レモン彗星 #Astronomy #Astrophotography

#CometLemmon #C2025A6 #Astronomy It's really bright now in the pre-dawn sky and moving FAST! I'm tracking at a custom rate using NINA's Orbitals, and it's hurrying past background stars, leaving trails at everything above half a minute😄 The stacking will definitely involve comet alignment.

The Cave Nebula (Sh 2-155) is a diffuse nebula in Cepheus within a larger cloud complex of various nebula types. Two nights of broadband followed by HaOIII data revealed dusty, reflective and emissive features surrounding the nebula in strong contrast with each other. #Astronomy #Astrophotography

I love how easy it is to spot Polaris B even through small-ish refractors. In this 5-sec snapshot during polar alignment you can visually count the pixels to gauge separation from its bigger brother. ~10 pixels, which is exactly ~18-19" given a pixel scale of 1.85"/px😄 #Astronomy

The Crescent Nebula is a popular DSO in Cygnus, known for its distinctive appearance embedded within the Swan's rich nebulosity. The 103APO combined with small pixels on the MiniCAM8 revealed nice details in the gas shells. Modified HOO + a little SII, ~4.5 h exposure #Astronomy #Astrophotography

#Aurora just now from Keswick north of Toronto! #Astrophotography

Just a single 5-min Ha sub on the Crescent from the IMX585-equipped MiniCAM8M😍

Getting some shots of IC 59. Looks like I finally met Navi the reflection maker😆

The Veil Nebula, Pickering's Triangle and nearby nebulosity formed the western part of the Cygus Loop (Sh2-103) - an expansive supernova remnant ~2500 ly away that remembers the distant death of a massive star. 10 hours of Ha/OIII data captured on the Askar 103APO #Astronomy #Astrophotography

As part of learning PixInsight, I decided to revisit M33, the Triangulum Galaxy, and experiment with continuum subtraction on some OSC Ha data from a new setup around the Askar 103APO scope. #Astronomy #Astrophotography

The Sadr Region - a nebulous region at the heart of Cygnus the Swan. The Crescent Nebula swims over sprawling hydrogen-alpha clouds of the Sadr Region like a cosmic jellyfish. #Astrophotography

Since the #IM2 lander uses very wide angle fisheye lenses, I was able to make a partial 360° panorama from the image. This gives a slightly better sense of scale and direction. www.360cities.net/image/im-2-s...

Got 5 hours of Ha data last night and here is the updated image! #Astronomy #Astrophotography

The Local Group's third-largest member after Andromeda and our home - the Triangulum Galaxy through my little scope. #Astronomy #Astrophotography Around 5.5 hours of broadband data from last night, thinking about adding some additional Ha data when the sky clears up again.

Comet #TsuchinshanATLAS revisited tonight in Keswick, ON, Canada. It's displaying some green head and contrasting details in the dust tail. #Astronomy #Astrophotography

Comet #TsuchinshanATLAS is starting to display some noticeable structures towards the head

My longest project yet, a little over 100hrs total on Andromeda. 62.5h LRGB and another 39.5h on Ha. Shot from Starfront Remote Observatories with a RedCat51, ASI533MM Pro, and Antlia HaLRGB filters. #astrophotography 🔭

I’m a university professor of astronomy and sometimes I see the Moon and think “man… that thing is fucking weird, just hanging in the sky like that” 🌖🔭

‘tis the season to repost my shot of the Ghost of Cassiopeia 👻, a reflection and emission nebula about 550 light years away. Shot this about a year ago from my back yard in central Virginia. Spooky, eh? #astrophotography #photography

A celestial coast on the outskirts of Cassiopeia and Cepheus: the Cave Nebula, the Northern Lagoon Nebula, the Bubble Nebula, the Lobster Claw Nebula, the Scorpion Cluster and many other DSOs in a compact field of view... #Astronomy #Astrophotography

Intelsat's IS-33e communications satellite has undergone a breakup event in geostationary orbit, with US Space Force reporting 20 tracked (but not yet cataloged) debris objects. The satellite was launched on 2016 Aug 24 and is over the Indian Ocean at 60.1E; breakup was 0430 UTC Oct 19.

Meanwhile. Just passing through...

The bright HII region Sh2-117 at the tail of the Swan, where the famous North America Nebula and Pelican Nebula are located. This stack from last night is only 1.7 hours of exposure with an almost full Moon overhead. #Astronomy #Astrophotography

Comet #TsuchinshanATLAS last night from north of Toronto. The tail appearance is evolving quickly as Earth's perspective changes just after crossing its orbital plane. 50 x 20", 2024-10-16 19:47-20:10 UTC-4 ZWO ASI533MC Pro + Rokinon 135mm F/2 Cook's Bay, Ontario, Canada
