Commonly called the Pleiades or Seven Sisters, M45 is an open star cluster. It contains over a thousand stars that are loosely bound by gravity, but it is visually dominated by a handful of its brightest members.

The nearly straight, blue-white wisps are streams of large dust particles. As the cloud moves toward Merope, its smaller dust particles are slowed down by the star’s radiation pressure more than the larger particles are. The large dust particles continue on toward the star while the smaller particles are left behind.

The Pleiades cluster has been observed since ancient times, so it has no known discoverer. However, Galileo Galilei, the Italian scientist best known for discovering the largest moons of Jupiter and championing a heliocentric model of the solar system, was the first to observe the Pleiades through a telescope. M45 is located an average distance of 445 light-years from Earth in the constellation Taurus.

On the clear, cool (i.e. cold) evening of 30 December 2025 I pointed my ZenithStar 81 telescope at a target I had not observed before, namely Sharpless 2-261, also known as Lower's Nebula.

It is a faint emission nebula located in the constellation Orion. Sh2-261 is an ionised hydrogen region energised by the ultraviolet radiation of nearby hot stars. This nebula lies roughly 3,300 light-years from Earth and spans about 50 light-years in diameter. Observations in radio and infrared wavelengths have revealed dense pockets of gas and dust within the nebula, indicating ongoing star formation. The primary ionising source is believed to be a massive, hot star whose intense ultraviolet radiation excites the surrounding hydrogen gas, causing it to emit the characteristic red glow.

The nebula is called "Lower's Nebula" in honour of Harold Lower, an American amateur astronomer and astrophotographer, who first photographed it in 1939 using a homemade 6-inch telescope. His discovery was notable because, at the time, most deep-sky objects were catalogued by professional observatories. Yet Lower managed to capture this faint nebula from his backyard, much like I did, but I had the advantage of finding it in my star catalogue.

Sharpless 2-12 is a very large nebula. It's full extent sprawls over a vast region and it is therefore best imaged with either a smaller focal length or a camera with a bigger sensor or both

Still this view does reveal some interesting structures. Like many Sharpless objects it doesn't seem to be imaged that often

Venus and Jupiter are the two brightest planets in the night sky. They are visible to the naked eye without binoculars and are easily distinguishable even for the casual observer.

Venus appeared much brighter than Jupiter during the conjunction, however, they were both clearly visible to the naked eye in the early evening sky.

Thanks to the relatively short orbit of Venus (225 days) coupled with Jupiter’s 12-year orbit, the pair reach conjunction roughly every 13 months.

In this picture Venus is above Jupiter and you can clearly see the four Galilean moons of Callisto, Ganymede, Europa and Io. If you expand the picture to full size you will even make out some of the background stars.

A section of the Rho Ophiuchi Molecular Cloud Complex and the surrounding area is a colorful region visible in the summer sky in the constellation Ophiuchus. The blue-white star Rho Ophiuchi with its two smaller companion stars can be seen near the top center of the photo. The upper part of the photo is filled with blue reflection nebulae that are illuminated by the bright, bright blue stars in the region. The black snake like rivers are dark nebula made of dense interstellar dust clouds that completely blocks the transmission of light from the stars behind the cloud. The region is fertile with widely spread raw materials that will eventually coalesce via the forces of gravity into new stars in the distant future.

The lower right corner of photo contains a rare yellowish reflection nebula. Unlike the blue reflection nebula in the upper part of the photo, the lower reflection nebula is being illuminated by the giant red supergiant star Antares located in the neighboring constellation of Scorpius. The light from Antares is dominant in the red area of the visible spectrum and the particles of dust are reflecting the yellow wavelength of light that give the yellow nebula its yellowish hue. The blue-white stars in the upper part of the photo emit light in the blue end of the spectrum that gives the blue reflection nebulae a blueish hue.

Antares is about 588 times the diameter of the Sun and is about 12 times more massive. Antares is about 76,000 time more luminous than the Sun. It is in the red supergiant stage indicating that it is in the final stages of its lifespan that will end in about a million years as a catastrophic supernova explosion.

A spherically shaped globular cluster of stars M4 is located near the lower right center of the photo. It is located above the Milky Way Galaxy’s plane in the galactic halo. It is the closest of the 158 globular clusters that surround the galaxy at a distance about 56,000 light years from Earth. M4 contains about 400,000 white dwarf stars, which are considered to be some of the oldest stars in the Universe with an estimated average age of 12.2 billion years. The total mass of the cluster of about 67,000 solar masses.

Above M4 and to its right is a large red emission nebula composed mainly of ionized Hydrogen. The blue-white star at its center is stimulating the Hydrogen to glow red. This is a stellar nursery in which stars are currently forming.

The image was constructed with data taken remotely over the Internet from the iTelescope T8 astrograph ( www.itelescope.net/ )located at the Siding Spring Observatory in New South Wales, Australia. Thirty-two 5-minute exposures were taken over 5 nights in June and July of 2020 using Astrodon wideband Luminance, Red, Green, Blue, and a narrowband Hydrogen Alpha filters. The astrograph is composed of Takahshi FSQ-ED 106 mm telescope with a photographic speed of f/5 and a focal length of 530 mm. A Finger Lakes Instruments FLI 16803 Monochrome CCD camera was attached to the telescope. I controlled T8 from my home in Northern VA via the Internet.

The raw T8 data was downloaded to my PC via the Internet for processing using the image processing programs: Astro Pixel Processor (APP) ( www.astropixelprocessor.com/ ), PixInsight (PI) ( pixinsight.com/ ), and Adobe Photoshop 2020. Most of the processing was performed with APP, after which PI and Photoshop were used to make small refinements in hue, saturation, and contrast. The final full color image was about 92 MB in size.

Comet C/2022 E3 (ZTF) was discovered by astronomers using the wide-field survey camera at the Zwicky Transient Facility this year in early March. Since then the new long-period comet has brightened substantially and is now sweeping across the northern constellation Corona Borealis in predawn skies.

In the new year on January 12 and at perigee, its closest to our fair planet, on February 1. The brightness of comets is notoriously unpredictable, but by then C/2022 E3 (ZTF) could become only just visible to the eye in dark night skies.

M82 or the Cigar galaxy, shines brightly at infrared wavelengths and is remarkable for its star formation activity. The Cigar galaxy experiences gravitational interactions with its neighbouring galaxy, M81, causing it to have an extraordinarily high rate of star formation — a starburst.

M82 is about 12 million light years away in the constellation Ursa Major. It is five times brighter than the whole Milky Way and one hundred times brighter than our galaxy's centre.

I took this last night over about two and a half hours using a filter to block out UV and Infrared light so it only captures visible light. I will try again soon with a different filter to see if it can bring out the star creation areas in the centre.

Elephant’s Trunk Nebula (IC1396), 08/18/2020

This was a fun night and an unexpected result. I took my equipment out to my favorite dark sky location to camp and capture photons. I was looking forward to showing off my hobby to my wife and some friends who were camping as well. I got my gear setup and took my first capture, but the frame was very faint and unexciting. Kind of boring. Oh well. Everything else was going well so I decided to stick with it and see. The next day I did a quick stack and process and DAMN there was a ton of detail there after all! I did not quite get the framing right but that only means I have a reason to try this one again.

I don’t know how someone saw an elephant trunk when looking at this but hey you discover it, you get to name it I guess. It is found in the constellation of Cepheus and is about 2,400 light-years from us. The “trunk” itself is over 20 light-years long. In 2003 several very young stars where discovered in the circular cavity in the tip of the trunk. The stellar wind from these hot young stars may have carved out this hole.

NGC 6946 is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years

It gets its name, Fireworks Galaxy because of the number of Supernova explosions that have been reported in the galaxy. In the last century alone, at least 10 supernovae have been detected in the galaxy. N.A.S.A.

It is also known as a Starburst Galaxy galaxy due to the number of new stars being created.

I have taken images of this galaxy before, but this time I have worked on sharpening up the collimation, adjusted the back-focus and opened up the image train (by replacing the 50mm M42 spacer with an M48 spacer) to reduce vignetting. This has not just helped the image camera it has also improved the view for the guide camera, resulting in better tracking.

Heart Nebula (IC 1805), 08/27/2020

Last weekend I headed back out to the Buck Creek campground, this time by myself. The weather was clear and the moon was not yet full and I couldn’t pass up the opportunity. I was able to setup my big telescope and two separate cameras to capture images. I’ll post the other pictures soon. It was a successful trip all around.

This is the Heart Nebula and it is huge. If the Heart Nebula was as easy to see as the Moon, it would be almost ten times the size in the night sky. It is found in the constellation of Cassiopeia and is some 7500 light-years away. The lower portion of the Heart Nebula has its own designation NGC 896 and is called the Fish head Nebula. It seems to me that these two nebulae where easy to name.

Eagle Nebula (M16), 07/09/2020

We had a new moon and clear skies at the same time last weekend so there was no way I was passing up that opportunity. I hooked up the RV, kissed my wife goodbye, and headed to the hills to catch some photons! Things mostly went well, mostly. As I started to setup my gear at dusk, I realized I had forgotten a critical usb cable. This meant I needed to huck all the expensive equipment into the RV and run into town. This was a two-hour round trip to Wally World and back. Then re-setup the telescope and let it run into the wee hours of the night.

This is the Eagle Nebula, an object I have shot several times before, but this time I used a fancy light pollution filter. This filter makes it possible to process the data in a simulated Hubble Telescope color palette. Short explanation is that the filter separates the hydrogen-alpha (red) and the oxygen-III (blue) light-wavelengths into separate color channels during image processing.

The Eagle Nebula is a 5.5-million-year-old cloud of molecular hydrogen gas and dust stretching approximately 70 light years by 55 light years. It lies about 6,500 light-years away. The “Eagle” itself in the center is the famous Hubble image, “The Pillars of Creation”.

Uranus is the seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets, which also include Jupiter, Saturn, and Neptune.

Its moons are named after characters created by William Shakespeare and Alexander Pope. These include Oberon, Titania, Umbriel, Ariel and Miranda. All are frozen worlds with dark surfaces. Some are ice and rock mixtures. The most interesting Uranian moon is Miranda; it has ice canyons, terraces, and other strange-looking surface areas.

The bright star to the right is Omicron Arietis in Aries.
