Here’s a closer look at the lagoon and Trifid nebula seen in the previous image, in this image, you can see Lagoon Nebula (M8), Trifid Nebula (M20) and IC 4685 (located on the far left). This is a 1hour integration as I ran into some software issues during the capture session and terminated early. This was shot with a QHY294C with a 70mm APO scope on a CEM25P #messier8 #messier20 #ic4685 #astrophotography #astro_photography_ #nebula #nebulae #lagoonnebula #trifidnebula #qhy294c #cem25p ＃星雲 ＃天体写真 #天体景観 https://www.instagram.com/p/B0D3vySlOIl/?igshid=9qia2ep9hnz8

#Repost @astrononico with @get_repost ・・・ Kind of a Cosmic Selfie! The galaxy NGC2903 captured with a focal length of more than 2 meters! 😮😀✨ This, often overlooked beauty is about 20.5 million light-years away and just a little smaller than the #MilkyWay. Also its spiral structure and central bar are very comparable to our own #galaxy. This is the result of the first deep-space test for my #EdgeHD8 and also my deepest astrophotography yet - challenging but satisfying 😊 — Some details: - scope Celestron #EdgeHD 800 (2125mm, f/10) - imaging cam ZWO #ASI294MC Pro - mount #iOptron #CEM25P - guide scope 50mm SVBony f/3.8 - guide cam #ASI120MC-S - 82x120sec (gain240 at -20°C) - calibrated in #AstroPixelProcessor (50 flats, 50 dark flats , 30 darks) - registered and integrated in #PixInsight - finished with PixInsight and #Photoshop (and #StarSpikesPro for a little icing on the cake ☺️) — #amateurastrophotography #astronomy #astrophotography #space #astro #cosmos #deepspace #telescope #natgeospace #astrophysics #universe #StellarMate #deepsky #igworldclub_astrophotography #amateurastrophotographyezine https://www.instagram.com/p/B_NHmpen0Dw/?igshid=1krwvg6pukyyb

Did some astro-imaging last night! I think of narrowband imaging as my thing, but it's always fun to use the cooled color camera on what are typically narrowband deep sky targets--the emission nebula NGC 7000 (North America Nebula) in this case. You can probably see why it's called the North America Nebula. To the right of it is the Pelican Nebula (IC 5070) with IC 5068 on the lower right. As you can see, I also managed to capture a few stars. That bright area in the upper right is one of the brightest stars in the sky, Deneb, encroaching on the frame. This is 42 x 2-minute sub-exposures stacked in DSS and processed in PS2021. Equipment: William Optics SpaceCat 51 APO refractor, ZWO ASI071MC, no filters, DeepSkyDad AF3 focuser, iOptron CEM25P mount.

The Veil Nebula is a beautiful result of a supernova that occurred long ago in the past, where the expanding dhock wave from the supernova slammed into the surrounding interstellar gas, heating it up, exciting it and caused it to glow. Even now, the Veil is still ballooning outwards. The reason why the Veil Nebula looks the way it is is because we are viewing it edge-on. In this image, it is framed such that the Western Veil, also known as NGC6960, the “Finger of God” or the “Witch’s Broom” can be seen at the top part of the image, with the bright star 52 Cygni lighting the way. Below the dramatic and beautiful Western Veil is Pickering’s Triangle and the “Funnel”, much fainter patches of the Veil supernova remnant. The Pickering’s Triangle is a beautiful tangle of filaments and cavities that narrows to a small point, resembling a triangle with an extended point. Lastly there is NGC6974 and NGC6979 at the bottom left corner of the image. The Veil Nebula is a beautiful sight to behold in large telescopes visually with the aid of a filter such as a UHC or OIII filter, popping out with dimensionality and contrast. It is a target that benefits from long exposures and this image is made up of 10-minute subexposures totalling 3 hours. Shot with a QHY294C with an STC Astro-DuoNB filter and a 70mm APO refractor on a CEM25P. #ngc6960 #westernveilnebula #westernveil #astrophotography #astro_photography_ #astrophotographer #astrobackyard #astronomy #deepskyobject #deepskyphotography #pickeringtriangle #ngc6979 #ngc6974 #narrowbandimaging #ig_astrophotography #astrophotographie #amateurastrophotographyezine #amateurastronomy #cem25p #qhy294c #天体観測 #天体写真 ＃星雲 #nebula https://www.instagram.com/p/B0fXc04FZNU/?igshid=1uclpb9ehdxau

The Rho Ophiuchi Cloud Complex is a rather colourful deep sky object that can be found by looking at Antares in the night sky, the core of the Scorpius asterism, the heart of the scorpion, lighting the way with its beautiful reddish colour sparkling in the sky. Antares shown here as a bright yellow star in the yellowish portion of the complex. The complex itself lies some 460 light years away from Earth and is one of the nearest star forming region. M4 can be seen next to Antares and the beautiful dust lanes that can be seen converging to the colourful nebula shows a beautiful surprise at the left edge of the image, that of Jupiter, our beloved gas giant in our solar system. This was shot with a QHY294C with a Nikon 85mm f1.8D shot on an unknown aperture as I feel I may have nudged the aperture control while focusing 😅. The whole setup is mounted on a CEM25P and has a 50mm guidescope and zwo224mc guidecam. Shot with exposures of 180s. Approximately 3hours 21minutes integration. #astrophotography #astro_photography_ #deepskyphotography #deepskyobject #deepskyastrophotography #astrobackyard #messier4 #antares #rhoophiuchicloudcomplex #rhoophiuchi #nebula #nebulae #photowork_community #amateurastrophotography #amateurastrophotographyezine #amateurastrophotography #cem25p #qhy294 #qhyccd #deepskyobject #darknebula #天体観測 #天体写真 https://www.instagram.com/p/B0OIpTglypO/?igshid=8yp88luozjrf

This image of M42 was shot with a QHY294C with a uv-ir cut filter on the objective, will likely reprocess it when i capture more exposures in dark skies when its high up again, current integration time is 75minutes. Was pleasantly surprised when the dust medium enrobing M42 was visible. #m42 #messier42 #runningmannebula #orionnebula #qhy294 #qhyccd #cem25p #astrophotography #nebula #nebulae #deepskyobject #emissionnebula https://www.instagram.com/p/BxY1PZnlxb3/?utm_source=ig_tumblr_share&igshid=17edchzb4vmls

Coathanger Cluster and Dark Nebulae - That's why our galaxy is called the Milky Way. The starfield is so dense along the galactic plane, especially as you move toward the core, that the merged brightness of stars is all you see. This is a shot of the "coathanger" cluster--that's the four stars making a hook in the center with the line of stars running underneath (Al Sufi's Cluster, Brocchi's Cluster, Cr 399). The dark clouds in this frame are just that, massive clouds of interstellar dust, molecular hydrogen, and other debris that swirls around our galaxy between the stars--especially between us and these stars--because that's pretty much everything else. It's dust and stars. There are hundreds of billions of stars in the Milky Way and as you look toward the center, you are looking through a hundred-thousand lightyears of the stellar disk--everything that orbits in the galaxy with us. We're 27,000 lightyears out from the core, so you are looking through that as well as everything orbiting on the other side of the core. Yup, it's a bunch of stars, as many as 400 billion just in our galaxy.

I will admit to not being a star cluster guy. Some of them are absolutely fascinating, but they're just not my thing. You show me some dark nebulae, anything from the Barnard Catalog or Lynd's Dark Nebula Catalog, and I'm there. There are a few stand-out dark nebulae below this frame to the right (LDN 770, 778), but there a batch in this frame including LDN 740, and lower left LDN 741, 745.

The Wizard Nebula in Cepheus surrounds the star cluster, NGC730, discovered by Caroline Herschel in 1787. The Wizard is between 7000 and 8000 lightyears away from us, and the core star forming region is about 100 lightyears across.

Pacman Nebula (NGC 281) in the Constellation Cassiopeia is an emission nebula about 9200 lightyears away from us, part of an HII region in the Perseus Arm of our galaxy.

The Rosette Nebula NGC 2237 in Monoceros, a large circular HII region. The open star cluster NGC 2244 has formed out of—and continue to form out of—the Rosette's abundance of hydrogen and other materials. NGC 2237 is about 5000 lightyears away from us, and it's about 130 lightyears across. That's Sh2-280 on the right, a dim diffuse nebula. Another one from my backyard with the William Optics SpaceCat 51 250mm FL APO refractor, iOptron CEM25P EQ mount, ZWO Astronomy Cameras ASI071MC cooled color camera, Celestron UHC/LPR filter. 13 x 2-minute exposures, 4 x 8 minute exposures.

NGC 6820 in HaOIII - Another one from the one clear night we've had for a while--Wednesday the 13th. This is centered on the reflection nebula NGC 6820 (that bright nebula core) and the open star cluster NGC 6823 in the constellation Vulpecula. All of this is wrapped in the emission nebula, Sh 2-86, basically everything else in the frame, all the cloudy structures that surround NGC 6820 and 23. Reading the wikipedia page, it says NGC 6823, the star cluster in the center, "forms the core of the Vulpecula OB1 stellar association". It's true: https://en.wikipedia.org/wiki/Vulpecula_OB1 --that sounds very Star Federation, which is cool.  Astro Notes: William Optics SpaceCat 51 250mm fl Apo Refractor, ZWO ASI1600MM-Pro cooled monochrome camera, iOptron CEM25P EQ mount, Astronomik 6nm Ha and OIII filters. 20 x 480 second exposures for each filter.

The Pinwheel Galaxy (M101) could be our galaxy's giant cousin--very distant cousin, since it's 21 million lightyears away (that's like 6 megaparsecss to you serious astro nerds). It's almost twice the diameter of the Milky Way galaxy, with a trillion stars. But what also makes the Pinwheel so wonderful is the way it's angled, so that we see it from the top (or face?).

I shot this in three sets of images, first with hydrogen-alpha, then with broadband green and blue filters, so instead of a normal red filter, I'm using narrowband Ha, which only allows a fraction of the hydrogen bandpass through--on the red end of the spectrum. I know HaRGB is popular, using the stacked Ha frames for a luminosity layer, but I only have five slots in the filter wheel, and thought I'd give this a try. (My filter order: Ha, OIII, SII, Green, Blue).

Here's M101 in HaGB mapped to RGB color, so that the galaxy's massive H II regions (pink and red masses swirling along the Pinwheel's spiral arms) really stand out. If I shot this in normal broadband red, these would just blend into the overall color of the galaxy.

I captured almost 5.5 hours of OIII and SII data on NGC 7380 (Sh2-142) the Wizard Nebula and star cluster in Cepheus. I captured the Ha data for the Wizard Nebula early in July, and now I have enough to process in SHO (Hubble Palette) that's where we map the three bandpasses, sulfur (SII), hydrogen (Ha), and oxygen (OIII) to RGB, Red, Green, Blue to make up a color image.

This was an especially busy week at work, a lot going on all around, including my son with an especially bad cold that developed into pneumonia--he spent the week recovering, so it was nice to be able to relax on a Friday night with clear skies, and schedule a somewhat unplanned and wayward imaging run across the autumn night sky. One of the targets I focused on was M45, the Pleiades. I was trying out 8-minute exposures, and it turned out well. It's always nice to have an early setting moon--or new moon where I can use my ZWO ASI071MC cooled color camera with a normal UV/IR cut filter, and not have to plan around our star's light reflecting off our disproportionately large moon. I shot the following stacked and processed image with the William Optics SpaceCat 51 APO Refractor, ZWO ASI071MC camera, on an iOptron CEM25P mount, with 28 x 480 and 600 second subs for M45.
