A wide view of a section of the beautiful constellation of Orion, imaged in mid Summer in the Southern Hemisphere. Photographed with a standard (unmodified) mid-range Nikon D7000 DSLR camera and Nikkor 60mm f/2.8 ED lens (stopped down to f/4 for optimal optical performance).

This widefield view around Orion's Belt includes several beautiful Deep Sky Objects including The Great Nebula in Orion (M42), The Horsehead Nebula (IC434) and Barnard's Loop.

About Barnard's Loop:

Barnard's Loop (also known as Sharpless 2-276) is a huge Nebular shell, about 1,600 light-years away in the constellation Orion. It envelops a large part of the Orion Complex. Barnard's Loop is thought to have been formed by a series of Supernovae that occurred two to three million years ago. The ionized shell is part of an even larger molecular Hydrogen cloud, and is kept luminous by a group of hot young stars.

About the image:

This is the first test image that I shot with my iOptron SkyTracker Pro. I decided to get a SkyTracker so that I can use a regular old camera and lens to photograph wide angle shots of the sky while I'm busy imaging with my Telescope. It is a fairly inexpensive way to do long exposures of the night sky with standard photographic equipment that you already have.

Location:

The rural dark skies of the African Bushveld in the Waterberg, Limpopo Province, South Africa (on a very warm Summer's evening).

About the Star Colors:

You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.

Comet C/2023 A3 Tsuchinshan Atlas from yesterday morning. The field of view is 3 degrees by 2 degrees. Taken at 16.56 UTC on 27 September, from Christchurch, New Zealand. I set the alarm for 3.30 am and drove up the nearby Port Hills to set up and wait for the comet to clear the horizon. In this image the comet was just over 5 degrees above the horizon. This is a stack of 30 x 10 second frames taken with an ASI2600MC camera and FRA400 (400 mm focal length) scope on an iOptron CEM40 mount. Stacked in DSS then edited in Siril, and noise reduction and final colour balance in Photoshop. Hopefully the comet survives until it is an evening object

This photo was captured at the Cherry Springs Start Party in June 2018.

I used my Canon T3i with a 14mm Rokinon F/2.8 Lens on an iOptron SkyTracker Pro for this image.

I stacked several 2-minute exposures in DSS for this shot. (I believe about 2 hours total)

Hi Folks,

We had two clear (but very warm) nights starting on June 22, and I was about to catch some more photons from my new Whispering Skies Observatory!

This is SH2-54 - an H2 complex in the constellation of Serpens the snake.

This image resulted from 8.9 hours of SHO Narrowband exposure. Given that there are only about 4.5 hours of darkness this time of year, I was fortunate to get this much integration!

It was unseasonably warm, and I had to run my camera cooler at a lower aim temperature.

However, I encountered a problem where the expanding metal caused the camera to loosen from the camera rotator. Fortunately, I was able to deal with most of those issues.

The full report on this imaging project, including a detailed processing walk-through, can be seen here:

A classic 22° ice crystal halo around the waning crescent Moon, here overexposed, with the Moon between Jupiter and Mars in the morning sky on December 5, 2015. Seeing a halo around a crescent Moon is somewhat rare as they usually require the brighter light of the Full Moon.

Venus is the brightest object at bottom closest to the horizon. The three planets, along with the stars Spica (above Venus) and Regulus (at top of frame) define the line of the ecliptic here in the dawn late autumn / early winter sky. I captured this scene from southeast Arizona near the Arizona Sky Village at Portal.

This is a stack of 4 exposures from long to short (8s to 1/2s) to encompass the great range in brightness and not overexpose the crescent Moon too much. Images were layered in Photoshop and masked with luminosity masks. Automatic HDR techniques did not work well as the shortest image was too dark for ACR to find content to register in Merge ot HDR, and in Photoshop the HDR Pro module left visible edge artifacts.

The camera was on the iOptron Sky Tracker to follow the sky and register the sky for all the exposures, thus the slightly blurred ground. Taken with the Canon 6D and 15mm full-frame fish-eye lens.

Mount: iOptron iEQ45 Pro

Integration: 45 mins (9 x 5 mins)

Messier 22 (M22 or NGC 6656) was photographed in July 2015. The final image is composed of 14, 30-second images captured at ISO 3200. A Canon 6D camera was mounted on a Celestron 6″ telescope at prime focus. The imaging system was mounted on an iOptron ZEQ25 mount.

M22 is nothing less than spectacular. It is ranked in the six finest globulars in the entire Milky Way (from our observation point). Most rank M13 as being better in the Northern Hemisphere, I do not agree. What I like about this globular cluster is that the stars are easy to resolve since most are about 11th magnitude. The total number of stars in this system are believed to number about 500,000.

After an encouraging first light with my D7000+Sigma 105 on an ioptron skytracker a month ago, I decided to return to this target for more.

This is the result of stacking and integrating 50 x 120s exposures, at 1250 ISO.

The lens aperture was set to f/3.3

Comet C/2014 Q2 (Lovejoy) has just reached a height of about fifteen degrees above my southern horizon. From my observing site, the southern horizon is my most heavily light polluted area of the sky. I can barely discern a tail at this point; the next few weeks should prove to be interesting! The image was made of a stack of 38 twenty second exposures (Canon T2i, 100 mm f/2 lens @ f/3.2, ISO 800). Tracking was done with an iOptron Sky Tracker with stacking done in Nebulosity.

Another first attempt. (loving this hobby!)

Hi Folks,

I just published a new imaging project on my website!

The Cat's Eye Nebula (NGC 6543) and NGC 6552.

This image resulted from 14.6 hours of LRGB exposure on my Sharpstar SCA260 V2 Platform.

The Cat's Eye is a famous Planetary Nebula - a star that, in its death throes, blew its outer layers off into space! The bright inner core has a structure that can be seen in a modest telescope and is the root of its common name. This was one of the first planetary nebulae ever discovered.

It's located in our galaxy, about 3,000 light-years away in the constellation of Draco.

NGC 6552, on the other hand, is located 390 million light-years away! A small barred-spiral galaxy that is a Seyfert Galaxy with a powerful black hole at its core.

So in one frame, the near and the far!

Processing this image was challenging! I must have redone it about 8 times! While I am still not satisfied with the final result, I am ready to move to my next project.

The full story behind the capture and processing of this challenging target can be seen here:
