A farewell to one of the most imaged objects in the night sky. A project I started in February on the Esprit 100ED telescope at the complex, but didn’t manage to get round to edit it until now. I used it to practice some new scripts in PixInsight for image blending. I am happy with the details in this image, the Esprit 100ED really is a great telescope for wide field imaging. The focal length of this image is 564mm after using the Skywatcher field flattener.

A much higher resolution image with imaging details can be found on my Astrobin page at: astrob.in/ev6jv9/0/

Thank you for looking.

Here is a shot of one of the most photographed objects in the night sky, the Horsehead Nebula. The Horsehead Nebula is a diffuse dark nebula in the constellation Orion. The Horsehead Nebula is also referred to as Barnard 33 and is located inside the emission nebula IC 434 (the reddish background), it lies about 1,500 light-years away. The bright star to the left of the Horsehead Nebula is actually the star Alnitak, the leftmost star in the belt of Orion.

M86 lies in the heart of the Virgo Cluster of galaxies.

The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Million light years away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies, the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (containing our Milky Way galaxy) is a member.

On my picture you could see M86 as the largest galaxy but you could observe more than a hundred galaxies more, on the annotated version you could find all the information (please, see comments).

The Horsehead Nebula or Barnard 33 is a small dark nebula located in the constellation of Orion. Along with the Flame Nebulae or NGC 2024, an emission nebulae, they form one the most photographed regions in the sky. Estimations of distance put the Horsehead around 1,400 light years and the Flame anywhere between 900-1,500 light years. The bright region behind the Horsehead is a bright emission nebula designated IC 434 and just below the Horsehead is the emission and reflection nebula NGC 2023. The bright star above the Flame is the triple star system Alnitak one of the three main stars forming Orion's belt.

Finally a short break in the clouds to allow a brief imaging session.

This image was constructed using data imaged on 31st Jan 2024 using my fast Newtonian with a OSC camera and data from last year with the same camera and one of my APO's.

from old APOD: Scanning the skies for galaxies, Canadian astronomer Paul Hickson and colleagues identified some 100 compact groups of galaxies, now appropriately called Hickson Compact Groups. The four prominent galaxies seen in this intriguing telescopic skyscape are one such group, Hickson 44, about 100 million light-years distant toward the constellation Leo. The two spiral galaxies in the center of the image are edge-on NGC 3190 with its distinctive, warped dust lanes, and S-shaped NGC 3187. Along with the bright elliptical, NGC 3193 at the lower right, they are also known as Arp 316. The spiral in the upper left corner is NGC 3185, the 4th member of the Hickson group. Like other galaxies in Hickson groups, these show signs of distortion and enhanced star formation, evidence of a gravitational tug of war that will eventually result in galaxy mergers on a cosmic timescale. The merger process is now understood to be a normal part of the evolution of galaxies, including our own Milky Way. For scale, NGC 3190 is about 75,000 light-years across at the estimated distance of Hickson 44.

This setup is pictured here on a Sky-Watcher EQ6Rpro mount.

This is the faint emission nebula designated as IC 1396 in the constellation Cepheus. This region is energized by the bright, bluish central multiple star HD 206267. You can see the Elephant’s Trunk Nebula, IC 1396A, on the lower edge of this image. This has been processed using false SHO (Hubble Palette) in PixInsight. From NASA APOD, “Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff.”

The Veil Nebula captured recently using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.

In this Hubble Palette version (SHO) the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image, covering an area over 3 x 2 degrees of sky of are the Eastern Veil Nebula NGC6992 to the Western Veil Nebula NGC6960 (Witch’s Broom) far right with “Pickering’s Triangle” in between at the top of the image as well as “The Funnel” just below and the many knot’s and strands visible here and within this beautiful Supernova remnant.

This was not a target I was after but this was away from the moon light. The filter does a good job of removing the moon light as long as you are looking AWAY from the moon. So as my real targets are right next to the rising moon I have to do a few away.

This is the closest view of Carina I have taken this now means I have used all my camera's and Lens to capture this huge Nebula to get differing views. . The learning curve also extends to the Editing process as well that is an on going learning curve. Enjoy the Jewel of the Southern hemisphere. this is the one visible Nebula if you are away from the city lights you can see with your naked eye if someone shows you where it is.

Trifid nebula M20, it derived it’s name from the tri-lobed nebula structure that excited by a triple star system in the center of the nebula. The ionised hydrogen gas cloud emits red light and called emission nebula while the adjacent nebula emits blue because it is a reflection nebula that reflects the light from the nearby stars.

The whirlpool galaxy is actually two galaxies interacting with each other. The quite obvious spiral galaxy that is M51 and the much smaller galaxy catalogued as NGC 5195.

First discovered by Charles Messier in 1773, M51 is located 31 million light years away in the constellation Canes Venatici.

Here is a work in progress - the Orion and Horsehead Nebula in the constellation Orion. The three bright stars on the top represent the belt of Orion. This is two-hours of five minute exposures, I plan on adding another 10+ hours to this over the coming month in addition to many short exposure to bring out the central details of the Orion Nebula.

Commonly known as “The Hidden Galaxy” This Intermediate spiral Galaxy IC342 or Caldwell 5 lies at a distance of 10 million light years in the Constellation Camelopardalis. IC342 is wider than a full moon and one of the largest galaxies in angular size however as it lies close to the galactic equator it is severely obscured by the dust and splendor of our own Milky Way Galaxy making it a difficult and quite faint object to observe or capture.

Captured from Grand Mesa Observatory in Western Colorado using the QHY163M Mono CMOS/Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor that Sky-Watcher USA sent to us for testing and use with subscriptions.

This is composition taking in many of the bright and not so bright nebulas in and around the Sword and Belt of Orion.

At bottom is the bright Orion Nebula, Messier 42. Above it is the bluish Running Man Nebula, NGC 1973-5-7. At centre is the famous dark Horsehead Nebula, B33, silhouetted against the bright glow of IC 434. Above it, and above the blue star Alnitak is the pinkish Flame Nebula, NGC 2024. At top left is the reflection nebula complex of Messier 78 and NGC 2071. Numerous other small patches of nebulosity shine around the Belt stars at right of centre. The large Barnard's Loop, Sh-2-276, just sneaks into the corner of the frame at top left.

This is a blend of filtered and unfiltered images: a stack of 8 x 8-minute exposures through an Optolong L-Enhance filter blended with a stack of 12 x 8-minute exposures without a filter, with the filtered shots at ISO 3200 and unfiltered shots at ISO 800. Stacks of 4 x 2-minute at ISO 800 and 4 x 2-minute at ISO 200 are also blended in with luminosity masks to retain the details in the bright core of the Orion Nebula, and to shrink the stars.

All were with the Canon EOS Ra mirrorless camera shooting through the William Optics RedCat 51mm astrograph at f/5 (250mm focal length). The unfiltered shots were taken the night after the filtered shots, as incoming haze and ice fog cut short the shoot on the first night, January 9, 2021, and prevented more filtered shots (for lower noise) without haze. As it is, some haze surrounds the stars. The RedCat is equipped with the Starizona filter drawer accessory to make it easier to swap the filter in and out without affecting camera position.

This was on the Astro-Physics Mach1 mount and guided with the made-in-Hungary Lacerta MGEN3 autoguider which also controlled the camera and applied a dithering motion between each shot to help remove thermal noise. No dark frames were taken nor was Long Exposure Noise Reduction applied in camera, though it was -5° C these nights, chilly but mild for January here in Alberta.

All stacking, aligning and mean or median combining (the latter to eliminate some geosat trails) was done in Photoshop 2021. Luminosity masks to enhance the faint nebulosity and apply star masks where needed were created with the Lumenzia extension panel. The masking helps compress the dynamic range, allowing the faintest nebulosity to be enhanced without blowing out the bright highlights like the core of M42. But inevitably, the Orion Nebula ends up looking dimmer than it really is in relation to the other nebulas in the field.

Here is the Crescent Nebula in the constellation Cygnus.

I've recently reprocessed this image with more attention paid to the star colors. It was captured using a dual-bandpass narrowband filter, which can create some odd colors.

Swapped some cameras around yesterday and it was clear enough to re-focus everything.

This is a test image, part of the Rho Ophiuchi Complex in the constellation of Scorpio. It's a test because I used my QHY128 color camera w/AT65 and my QHY163 mono camera w/Hyperstar to make this image
