NGC4038/NGC4039: Antenna Galaxies

This is the Antenna Galaxies NGC4038/NGC4039 I just completed two days ago.  This target is normally imaged by the big guns 24” PW in Chile because it is more of a Southern Hemisphere target.  However, this image will show the power of a PlaneWave 12.5”CDK telescope in the Northern Hemisphere.  The highest altitude this target gets here is 32 degrees in North Carolina.  This was an incredible shoot for the PlaneWave 12.5” CDK.  Let me know what you think.

• PlaneWave 12.5” CDK telescope with the PW 0.66 Reducer captured this image at a MAX height of 32 degrees.
• I have about 15 hours in this LRGB image of the Antenna Galaxies.
• All sub-frames were captured at 300 sec.
• Astrophysics 1100GTO CP4 mount was used with the ATIK 16200 Mono main camera.
• ATIK EFW3 filter wheel with LRGB HA, OIII, and SII Chroma filters.

The Antennae Galaxies (also known as NGC 4038/NGC 4039) are a pair of interacting galaxies in the constellation, Corvus. They are currently going through a starburst phase, in which the collision of clouds of gas and dust with entangled magnetic fields, causes rapid star formation. The nuclei of the two galaxies are joining to become one giant galaxy. Most galaxies probably undergo at least one significant collision in their lifetimes.

SH2-308: Dolphin Head Nebula

This is the Dolphin Head Nebula (SH2-308) imaged in HOO. Sh2-308, commonly known as the Dolphin-Head Nebula, is an H II region located near the center of the constellation Canis Major, composed of ionized hydrogen. The nebula is bubble-like and surrounds a Wolf–Rayet star named EZ Canis Majoris. This star is in the brief, pre-supernova phase of its stellar evolution. The nebula is about 4,530 light-years away from Earth but some sources indicate that both the star and the nebula are up to  5,870 ly away.

The Dolphin Head Nebula took me 3 weeks to gather the data to finish.  The OIII signal is weak so it takes a lot of hours to get the details to pop in the Blue Oxygen. The Ha is much fainter but adds to the overall beauty of the image.  You can see the Dolphin’s head, mouth, eye, nose, and awesome details.  Really cool to look at and amazing that these beautiful nebulas are out there for us to image and share with the world.

• Plane Wave 12.5” CDK with the 0.66 PW Reducer sitting on an Astro-Physics AP1100GTO CP4 mount.
• My main camera is the ATIK 16200 Mono with EFW3 Filter Wheel with Chroma narrowband filters.
• Guider is an Astromania 400mm refractor with an ASI 290MM guide camera.
• Total integration time was >12 hours of OIII and Ha.

Rosette Nebula

“The Rosette Nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter. The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

• PlaneWave Instruments 12.5” CDK with 0.66 PW reducer to capture the image.
• Main camera is the ATIK 16200 Mono with EFW-3 filter wheel and Chroma filters.
• The mount is an Astro-Physics AP1100 GTO CP4.
• Total integration time is over 20 hours of Ha, OIII, & SII from 4 quadrants of images to make up this beautiful Mosaic.
• It took over 3 weeks to capture all the images required to process this Mosaic.

NGC281: “The Pacman Nebula”

This is “The Pacman Nebula” NGC281 that I imaged in SHO Narrowband “Hubble Palette.” Took two weeks due to the weather and the number of hours required.  You will find it incredible with the resolution of any APOD out there now and captured with a Plane Wave 12.5” CDK!

• I have a total of 16 hours in this image consisting of 5 hours Ha, 6 hours OIII, and 5 hours of SII.
• The telescope is the Plane Wave Instruments 12.5” CDK with the PW 0.66 Reducer sitting on the Astro-Physics 1100GTO CP4 mount.
• Filters used are Chroma Ha, OII, and SII narrowband.
• Main camera is the ATIK 16200 Mono with ATIK EFW 2.2 filter wheel.
• Guide scope is the Astromania 400mm Refractor and ASI 290 guide camera.

NGC281 is a bright emission nebula and part of an HII region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus Spiral Arm. It is located at a distance of 9,500 light-years from Earth.  It has a magnitude of ~ 7.4.  Long-exposure photography is necessary, preferably using narrowband H-alpha, Sulfer II and Oxygen III filters where the most details are resolved.

“This is an extremely rare event that I captured on May 24, 2023.

When I heard NASA thought they saw a super Nova in one of the spiral arms of M101 on May 23^rd, I imaged M101 again on May 24^th.  I did very clearly see the new huge Super Nova, an extremely rare event to image.

They are in black and white by inverting the images to make it easier to see all the stars in the galaxy and the Super Nova.

• The image of M101 on the left was 12 hours of LRGB data inverted and B&W.
• The image on the right capturing the Super Nova in M101 was only 15 minutes of Luminance data only!

That says a lot about the Plane Wave 12.5” CDK !!”

CDK20″ @ F4.5. FLI camera. RGB: 45mins.

Possibly the finest globular cluster in the entire sky. Visible to the naked eye alongside the Small Magellanic Cloud, the massive ball of stars is 16,700 light years away from our solar system and is 120 light years in diameter. Unlike Omega Centauri (the skies bright cluster of this type) 47 Tucanae is much denser toward the core giving the cluster a “3D” appearance in the telescope.

Located in the southern constellation Sculptor, this collisional ring galaxy was likely formed from a collision between two galaxies in the distant past. The blue ring of material is a region of active star formation dominated by hot blue stars. This ring of material is 150,000 light years in diameter which is larger than our own milky way galaxy. The Cartwheel Galaxy is 500 million light years away and glows at 15th magnitude.

 CDK700 (28″)  @ F6.8. FLI camera. L: 90mins. RGB: 5mins.

One of the brightest planetary nebulae in the sky. It is located around 700 light years away and spans around 2.5 light years in size. Many background galaxies are visible in the image (which are vastly more distant) including some visible through the nebula itself.

Nicknamed the Spare-tyre nebula,IC 5148 is a planetary nebula located around 1 degree west of Lambda Gruis in the constellation of Grus. Around 3000 light-years distant, it is expanding at a rate of 50 kilometres a second, one of the fastest expansion rates of all planetary nebulae.

 CDK700 (28″) @ F6.8. FLI camera. L: 60mins. RGB: 5mins.

This group of galaxies is located in the southern constellation of Grus and consists of three close spiral galaxies – NGC 7582, 7590 and 7599 located around 60 million light years away. The field also contains hundreds of more distant galaxies, many of them over a billion lights years away

CDK700 (28″) @ F6.8. FLI camera. L: 60mins. RGB: 5mins.

This face on spiral galaxy is located in the southern constellation of Antlia. It is 50 million light years away and glows at 10th magnitude. It can be easily seen in small telescopes.

Shapley 1 (Sp 1 or PLN 329+2.1) is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6. As viewed from Earth, it is peculiar in that it seems to be a non-bipolar, torus-shaped planetary nebula.Discovered in 1936 by Harlow Shapley, it is approximately 1,000 light years from Earth. At the centre of the nebula is a magnitude 14 white dwarf star.It has an angular diameter of 1.1 arc minutes,which makes it about one-third (.32) of a light year across.

 CDK700 (28′) @ F6.8. FLI camera. L: 60mins. RGB: 15mins.

This famous object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent ‘gaps’ within the emission nebula that cause the trifurcated appearance) It is located around 5000 light years away.

I shot this image between July 24 and August 25, at my “Cabin in the Sky” roll-off roof observatory, which is located in the south Okanagan region of British Columbia. A brilliant blanket of red emission nebulae encompasses an intricate web of reflection nebulae of varying shades of blue, with the field shot through by stars of many vivid colours. Towards the middle of the frame the blue nebula fades gradually in colour and intensity, giving way to very dark clouds in an apparent transition that seems almost unique in the sky!

This nebula gets its name from the fact that the main cloud is tri-sected by a dark nebula into three main sections. The beautiful red and blue colors come from the regions of the nebula where hydrogen is glowing (red) and reflecting starlight (blue). The red portion is excited to emission by the ultraviolet light coming from a triple star system embedded within. The distance to the Trifid is approximately 5200 light years, although there is a large disparity between various sources.

My image was taken with 3 nm Astrodon OIII and H-a filters to enhance the contrast of the filamentary structure. Astrodon Generation 2 RGB filters were used for shorter exposures to bring in proper star colors. The system was guided with a Starlight Express Loadstar guide camera on an Astrodon MonsterMOAG off-axis guider. Data were acquired automatically with CCDAutoPilot4 running Maxim4.62 and PinPointPro. Data were calibrated, registered and pre-processed, including deconvolution in CCDStack. Final processing was done in Photoshop CS5 Extended. Data were taken in the backyard under mag 4.5 skies with the moon up for the narrowband data and RGB before the moon came up.

Looking like a celestial Christmas tree ornament, this is the beautiful “Bubble Nebula”, known officially as NGC7635. Is is formed by gas being compressed by a strong stellar wind from massive star BD+602522, forty times as massive as our sun and several hundred thousand times more luminous. As fast moving gas escapes the star, it compresses surrounding sparse gas into a shell. The shell, consisting of hydrogen, oxygen and sulfur, is ionized by the radiation from BD+602522 causing it to glow. The bubble is approximately 6 light-years in diameter.

BD+602522 is a “Wolf-Rayet” star, a star in the end stages of its life which emits fierce stellar winds (charged particles streaming from its surface) rapidly depleting its mass until it finally dies in a supernova. Wolf-Rayet stars (named for their discoverers) have surface temperatures between 30,000 and 60,000 degrees Kelvin and emit stellar winds with speeds exceeding 1500 kilometers per second. There are only about 300 Wolf-Rayet stars known in our galaxy.

This was taken with a Lumenera Skynyx 2.0m, Televue 5x barlow, and an SBIG CFW on the CDK12.5.  2000 frames were taken at 60fps in IR-exclude, red, green, blue, and IR-only channels.  About 900 frames each from IR-exclude, IR, green, and blue were stacked and sharpened with registax to make an LRGB image.  LRGB composition and leveling was done in photoshop, as well as some additional sharpening on the L channel.

Instruments: CDK20 f/6.8 with STL-6303E
Location: University of Louisville, Mt Kent Observatory in Southern Queensland, Australia
Date:  May 20, 2007
Processing: The I, R, and V bands are displayed in this image as red, green and blue, respectively. Color layers were extracted with a gamma of 2.0 from the original 16-bit dark-subtracted images.  The combined color image as shown here was subsequently processed with an unsharp mask to highlight detail in the nebula surrounding the star, with weaker signals non-linearly increased to show fainter features.

NOTES:
Compare this image with the high resolution image from the Hubble Space Telescope.

NOTES:
North is to the right and west is down in this image. It is displayed here with gamma=2.0 to stretch the visible dynamic range and reveal the fainter stars. The brightest star in the image, north of center, is magnitude 8.4. It saturates the CCD’s response at 10 seconds. Stars as faint as 18th magnitude are visible. While there was a nearly first quarter Moon when this image was recorded, the sky background is effectively zero in this short exposure.
