The Herschel 400 Astronomical League Project is underway
It’s not too late to join. We are about 30 objects into the Herschel 400. Hope to get another session in soon. Please subscribe to the YouTube channel so you get notifications on LIVE STREAMS.
Angels in Monoceros: The Monoceros M2 Complex
The Monoceros R2 molecular complex (often shortened to Mon R2) is a massive giant molecular cloud and one of the nearest active star-forming regions to Earth. It's a dynamic stellar nursery embedded in dense gas and dust, where new stars—particularly massive ones—are actively being born.
Key Facts
Location: Southwestern part of the constellation Monoceros (the Unicorn), near the border with Orion. It's part of the larger Orion-Monoceros cloud complex.
Distance: Approximately 2,400–2,700 light-years (around 830 parsecs).
Size and Structure: The main dense core is relatively compact (a few light-years across), but the overall molecular cloud and associated nebulae span a wide area—reflection nebulae alone stretch up to about 2° in the sky. It's situated well below the galactic plane, which makes it stand out in certain observations.
Age and Activity: Star formation here began roughly 6–10 million years ago. It hosts an OB association (young, hot, massive B- and A-type stars) that illuminates surrounding dust, creating prominent reflection nebulae with bluish hues. There's also significant emission from ionized gas (red glows) and dark nebulae that appear as shadowy silhouettes blocking background light.
Notable Features:
A central hub of massive star formation with embedded clusters, molecular outflows, and HII regions.
Infrared observations (like those from VISTA or 2MASS) penetrate the dust to reveal hidden young stars and protoplanetary disks.
It's a key site for studying early stellar evolution, variability in young stellar objects (YSOs), and the interplay between massive stars and their natal clouds.
The most famous and photogenic part of Mon R2 is the region around NGC 2170 (the Angel Nebula), a striking reflection nebula with wing-like dust structures, glowing blue from scattered starlight, mixed with red emission and dark lanes. Wider views of the complex reveal a richer tapestry of colorful gas, dust filaments, and star clusters.

New Astro Camera: OM-3
Join me for a LIVE conversation about this new astro camera coming to the market. Is this the best option for you? How does it compare to other options? https://www.earthandskyphoto.com Correction: when discussing Bulb mode with Canon, I incorrectly said it had a limit of 30”. I meant to say manual exposure has a max of 30”. In bulb, you need to use a remote control or app for exposure time control. The problem is you can’t set exposure time for stills in the camera menu. I was made aware that Olympus no longer owns the OM system. It is owned by Japanese industrial Partners, a private equity firm.

Hello Again!
Hello to all and I hope you have had a wonderful winter and spring. I just wanted to touch base with you and let you know that I am producing new work and will be presenting work in many different formats. For instance, you can now join me on Facebook to see what's new. Now Facebook will include a mix of personal and business, but it is a great place to interact and a great way to stay in touch. Please join me on Facebook today.
P.S. I hope to begin sharing with you new ideas and resources on producing multimedia content featuring HD video. Please stay tuned and drop me a note.
Bryce Canyon
There are images and compositions that bug you until you finally decide to develop them for presentation. This image is one of those that has haunted me for the past year. It is also representative of where my photographic style is going. I will have more on my next photographic project, but for now, this is one of my favorite images from a hike within Bryce Canyon taken last November. I hope you enjoy it.
Bryce Light-February Print of the Month
My first visit to Bryce Canyon was not disappointing. I actually had low expectations as I felt that I had seen all of the photographs and so I really wasn't expecting to see anything new. Boy was I wrong. I was amazed at the quality of light at all times of day. Bryce Canyon is literally a "light theater" all day long as reflected light bounces around and through the various hoodoos, fins, and other canyon structures. It is a location that I long to return to. My first image from the location is simply "Bryce Light." It is the February Print of the Month. The print is fantastic, especially the larger sizes. I hope you enjoy the image on screen.
