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. 

 CDK20″ with FLI-PL6303E camera. LRGB. L: 60mins. RGB: 5mins.

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.

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

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.

© Trottier, HowardI shot the Cave for more than 16 hours over four nights between August 26 and September 1 of 2011, but used only the best 10 hours for processing: 300 minutes in luminance (unbinned), and 100 minutes in each of R, G, and B. Ten-minute subframes were taken in all channels.

These images were again taken at my “Cabin in the Sky” observatory, using my PlaneWave Instruments CDK17 telescope, operating with a focal reducer at f4.5, on a Paramount ME, along with an SBIG STL-4020M camera. Image capture was done with TheSkyX, MaxIm DL, and FocusMax. Image processing was done entirely with PixInsight and CCDInspector. The field of view is about 27′ on a side, and the unbinned pixel size is about 0.78″.   Website

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!

The data were acquired with two PlaneWave telescopes separated 57km from each other.

The luminance data were acquired with the PlaneWave CDK17 and the RGB data with his PlaneWave CDK12.5.

Total exposure time used 52 hours. We made 104 frames each exposed for 30 minutes unbinnned.

77 luminance frames and 27 frames for the RGB data.

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.

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:
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.
