The final cut, I'm done with this one.
Imaged 23 and 24 Sept 2013. Three and one half hours of data. Mulitple exposures of 4 and 5 minutes at ISO 250.
Stacked in DSS, 20 each, darks.flats and bias. Processed in PS5, no crop.

A mosaic panorama of the northern winter sky and constellations, taken February 27, 2016 from home in southern Alberta. Orion is near centre, with the array of winter constellations and stars around it. The Pleiades is at right of centre, the Beehive cluster at upper left. Sirius is at lower left. Auriga and Gemini are at top, Taurus at right of centre.
This is a mosaic of 5 wide by 4 tall panels, each taken with the 35mm lens at f/2 and for 25 seconds, with the filter-modified Canon 5D MkII at ISO 3200. The pan extends over about 120° and is about 70° tall. All exposures untracked.
I used the iOptron iPano motorized panning unit to move the camera automatically from area to area in the sky, taking 20 segments in total at 40% overlap. I processed the originals RAWs in Adobe Camera Raw, then exported those to TIFFs to import into PTGui stitching software. I used its Equirectanguler projection to stitch the pan segments for the squarist (!) image format. I brought this into Photoshop to then use its Adaptive Wide Angle filter to warp the image to an even more rectangular format with a straight horizon. Photoshop itself and ACR’s new Photomerge function did not produce good results in stitching, producing either a wildly distorted image, or, in the case of ACR, producing a nicely formatted image but with dark stitching artifacts at seams.
The final image was processed in Photoshop with the usual adjustment layers and smart filters and is 11,000 by 6,700 pixels.

De SkySafari Plus y hubblesite.org: la nebulosa “burbuja” fue descubierta en 1787 por el astrónomo Británico William Hershell está a unos 11.000 años luz y del sistema solar y fue creada por un fuerte viento estelar de la estrella central masiva y joven (unas 45 masas solares) sobre el material denso en la nube molecular circundante. Tiene unos 7 años luz de diámetro.
Por su parte, la nebulosa Sharpless 2-157 (Sh2-157) es una nebulosa brillante a 43.000 años luz del sistema solar. Quiere decir que es unos 32.000 años luz más distante que la “burbuja”.
En la imagen además se ven también las nebulosas Sh2-158, Sh2-159, Sh2-161 y el cúmulo de estrellas NGC7510 que tiene unos 20 años luz de diámetro.

A goofy smiley face in space or the Constellation Orion... I'll leave that up to you to decide. I present the first processing attempt at my Fall astrophotography project-Orion as our human eyes can't see it. I captured this data over four nights from Oct 22nd to Oct 25th while on a vacation to see family in Phoenix Arizona. To that point, all of this was captured with gear that I was able to fit in my checked bag, along with a week of vacation packing making it a successful POC for full portable astrophotography. Australia here we come 😉
Background:
Orion is one of the, if not the most well-known constellation in the night sky. It'd been the source of tales and mythology in countless cultures new and old from various tribes of Native Americans, to the Ancient Greeks, Aboriginals of Australia, Egyptians, and so on. I remember growing up and my dad never missing an opportunity to point it out to help get my celestial bearings.
Orion is widely known as the hunter and is often transposed as either facing the charging bull Taurus, chasing the seven sisters (Pleiades), or hunting a hare (Lepus). Within Orion, you'll find at least two of the ten brightest stars in the sky- Rigel in the lower right, and Betelgeuse in the upper left. Also visible here are a number of nebulous features from The Orion Nebula (M42), Horsehead and Flame nebulae, De Marian's Nebula (M43), the Rosette Nebula, and the Cone Nebula in the upper left.
Specs:
This photo was captured using Zwo Narrowband filters for Hydrogen Alpha, Doubly ionized oxygen (Oiii), and Sulfur II as this was captured from a suburban location in Arizona.
Final specs:
Total integration time = 15hrs
30x900" Ha (7.5hrs)
15x900" Oiii (3.5hrs)
17x900" Sii (4hrs)
Captured with APT, stacked in DSS, Processed in Startools, Channels / hue and saturation in Photoshop, and final touches in Lightroom CC. Color mapping Ha = Red, Sii = Green (capped to yellow / gold), and Oiii = Blue.
Calibrated with 35 darks, 35 flats per channel, and 35 dark flats per channel. Compressed to JPEG for upload.. which unfortunately looks to have done weird things at this resolution to the fine details (blur, and some panels). If anyone would like the full version .tiff just let me know.

The Veil Nebula (east section), also known as NGC 6992 in the constellation Cygnus. This image is a composite of four 90-second exposures at ISO 3200 using a Canon 6D and 400mm lens mounted on an iOptron ZEQ25GT mount. The image was processed using DeepSkyStacker, ImagesPlus and Corel Paintshop Pro X5 and X6.
Good news is the D810A works great with the SkyWatcher Esprit 80 ED refractor and the SkyWatcher field flattener. The bad news is the Vixen-style foot attached to the refractor allows flexure when mounted to the saddle on the iOptron iEQ45 Pro. Hence the lousy stars and lack of sharpness in the Orion structure.

I was excited to capture 30 minutes of imagery of my first comet, C/2017 T2 PANSTARRS, on Thursday, January 30, before clouds moved in.
Since I wasn't sure I'd get anything because of clouds, I didn't bother to drive to my Bortle 3/4 dark site, but instead shot from my Bortle 5 backyard, 60 x 30 seconds. I combined this imagery with some better imagery of the Heart and Soul Nebulae from this past fall (47 x 60 seconds under Bortle 3/4 skies), to create this small mosaic (the Heart and Soul Nebulae turned out a bit ugly from my Bortle 5 backyard). I was impressed with how well Astro Pixel Processor combined the imagery of such differing quality.

This is the California Nebula (NGC 1499), an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1,000 light years from Earth.

Single shot with my ASI 183mc Pro astrophotography camera through my Ioptron Photron 150 RC telescope from my backyard.
This is the second globular cluster I photographed on the evening of June 6, 2015 – it was like a globular cluster bonanza, as this part of the sky contain several that I planned to acquire that evening. This most recent observation was made using a Canon 6D with an attached Canon 400mm f/5.6 lens using my STANDARD ASTROPHOTOGRAPHY SETUP.
Messier 12 (M12 or NGC 6218 in the New General Catalog) is a globular cluster in the constellation Ophiuchus. Through my online research I also found that this cluster is referred to as the “Gumball Globular”, that’s a new one for me. It was discovered in 1764 by the French astronomer Charles Messier who described it as a “nebula without stars”. M12 is approximately 15,700 light-years distant. You will definitely need binoculars or a small telescope to see this cluster. This cluster contains about 200,000 stars, the brightest of them are about 12th magnitude.
This is an image of Messier 12 from a 10-minute total exposure using 1-minute subs. The images were taken on the evening of June 6, 2015 before moonrise.
Each of the 178 monochrome “Light “ frames is calibrated by various subtraction and division methods using Bias Dark & Flat Frame images. Bias data is a camera “signature” comprised of the average of 30 frames of the shortest exposure the camera can take while exposed to zero light. Many of the 16 million pixels perform differently and a predictive pattern of this can be derived and eliminated from Light Frames. A Dark frame also has the lens cap on and zero light leakage but is matched exactly to the light frames in exposure time, gain and temperature. Dozens of these provide the average noise for, say a five minute exposure. Flat Frames are critical to decent images and the most exasperating to perfect. They are images of a perfectly evenly illuminated color balanced field such as a perfectly clear eastern sky near sunset or an LED panel properly diffused. I stretch a pristine white tee shirt over the telescope objective and snap 30 exposures thru each filter. Flat Frames record the donut shaped halos of dust on any of the dozen surfaces in the optical path. They also record any vignetting that exists in almost every optical system. While the stacking of images is ideal for eliminating random noise as it boosts weak signal it tends to multiply anomalies like vignettes, dust donuts and camera sensor flaws, so calibration before any other processing is paramount.
Finally had a clear night over a week after the launch of the NASA's James Webb Space Telescope and managed to catch an image of it on the way to its observation post. This is a composite of about six hours of exposures from suburban Bloomington, Indiana. JWST shows up as the streak to the left of the bright (relatively) orange star (HD 44256) as it moves relative to the background stars. The trail is interrupted because several bad frames (poor tracking, etc.) were excluded.

Crater MORETUS, imaged on September 22, 2015 (Canon 6D and Celestron 6" telescope). This crater is located in the heavily cratered highland region near the south pole of the Moon. It measures 114 km wide and contains a central mountain formation that rises over 2 km above the floor of the crater. The crater was named after Théodore Moret, also known as Moretus (Antwerp 1602 – Breslau 1667) who was a Belgian mathematician.
Globular Cluster Messier 80 (M80 or NGC 6093) is a globular cluster that can be found in the constellation Scorpius. This cluster was photographed in July 2015 and the final image is a stack of 18 thirty-second exposures (nine minutes total) at ISO 3200 using a Canon 6D at prime focus of a Celestron 6″ telescope. The imaging system was mounted on an iOptron ZEQ25 equatorial mount for guiding.
M80 lies at a distance of about 32,600 light-years. It is one of the densest globular clusters in our galaxy. Software used to create this image include DeepSkyStacker (for stacking the individual frames), ImagesPlus (for initial stretching and post processing), and Corel Paintshop Pro X5 and Adobe Lightroom for the final image adjustments.

Messier 57 - The Ring Nebula. This is ] a famous object that I revisited after year since my first attempt. This is tough object for my scope and it is very small. M57 is another planetary nebula - a star that blew up! M57 is located in the constellation of Lyra, and is about 2500 light years away. The central "teal" color in the ring is from doubly ionized oxygen emission lines at 495.7 and 500.7 nm. These emissions only occur only in conditions of very low density containing a few atoms per cubic centimeter. You'll notice that the outer part of the. ring is reddish in color and this is caused by hydrogen emission at 656.3 nm. Also note the small galaxy at 10 o'clock - this is IC1296. Much more detail than my first effort - but still so far from perfect - always more to learn!
This image resulted from 95 x 120 second captures. Captured with a William Optics 132 mm FLT APO scope on an IOptron CEM60 mount. Camera was a ZWO ASI294MC-Pro. Capture was done using Sequence Generator Pro and PHD2 Guiding. Processing was with DeepSky Stacker, Pixinsight, and Photoshop.
One of my favorite targets - the integrated flux nebula (IFN) or galactic cirrus is faint dust illuminated by our galaxy, and there happens to be a nice concentration of it in the direction of Bode's Nebulae (Bode's (M 81) and Cigar (M 82) Galaxies). The Angel Nebula, which is made of IFN, is in the lower left corner. This is an improvement over my last attempt at this target - shooting raw and more integration time made a difference.

Nov 2020 update: The color of M 81 on my original version had always irked me a bit. I reprocessed it and now M 81's color is much better (in my opinion).

The Jellyfish Nebula (left-center) is a supernova remnant. The Monkey Head Nebula is the bright emission nebula near the bottom; the monkey head is upside down looking right here. Both are quite close - the Jellyfish Nebula is an estimated 5,000 light years from earth; the Monkey Head is an estimated 6,400 light years from earth. The large star cluster near the top is Messier 35 (NGC 2168). NGC 2158 is the other smaller star cluster to the lower right of Messier 35.

Hi Folks,
Today I have released the second Imaging Project coming from the data collected over three nights on September 15, 16, and 21.
NGC 6914 - The Spider Nebula - is located 6,000 light-years away in the constellation of Cygnus.
It actually does NOT seem to have a popular or common name. Still, after working on this image for several days now, I keep seeing a friendly little spider at the center of this frame, so I have decided to give it my own name - The Spider Nebula!
This image of this rich region of Emission, Reflection, and Dark Nebulae resulted from 14.5 hours of SHOrgb data taken on my William Optics 132mm Platform.
There is not a lot of background info I could find for this object, but there are many images of this object to be found - the vast majority of these are RGB Broadband images, so I decided to image this in Narrowband SHO, and replace the narrowband stars with true RGB broadband stars.
The full posting on this imaging project, including a detailed step-by-step image processing walkthrough can be found here:
cosgrovescosmos.com/projects/ngc6914sho
At any rate - thanks for looking. (And If anybody asks you - tell them this is called the Spider Nebula - maybe we can make it stick!)
Thanks,
Pat
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.
