The Flying Dragons - Sh2-114, LBN347 (Ha-RGB)

The image of Sh2-114, (and 113) known as the "Flying Dragon Nebula," is a stunning example of cosmic artistry. The intricate red filaments of ionized hydrogen stretch across the field, resembling the fiery wings of a mythical dragon. The interplay of glowing red nebular gas against the dark, star-filled background creates a sense of depth, highlighting the delicate, web-like structures sculpted by stellar winds and magnetic fields.

Astronomically, Sh2-114 is a Sharpless catalog emission nebula located in the constellation Cygnus. Its fiery hues stem from hydrogen atoms energized by ultraviolet radiation from nearby stars. This nebula’s complexity reflects the dynamic forces at play, and the  only  emission from these nebulae is in Ha frequency (check this link for a comprehensive explanation) and so is the "clouds" around the objects. 

Directly above the right wing, halfway between the wing and the edge of the frame, is a planetary nebula. This is cataloged as Kronberger (Kn26), and it is a bipolar emission nebula. Kn26 is a small (110 arc seconds) planetary nebula in the constellation Cygnus. Kn26 was discovered by Austrian amateur astronomer Matthias Kronberger in 2006, although it wasn't spectroscopically confirmed as a planetary nebula until 2011. In 2012 it was established that it was a new member of the very small sub-class of quadupolar planetary nebulae.The image of Sh2-114, (and 113) known as the "Flying Dragon Nebula," is a stunning example of cosmic artistry.

The Diamonds of Bogenfels

Location (was image taken with remote scope?): Namibia.

Image Description and Details: The mining ghost town of Bogenfels lies in the Sperrgebiet in South West Namibia. Sperrgebiet translated from German means the restricted area. The Sperrgebiet is an active diamond mining zone and one risks getting shot if not having the proper credentials and permits to enter the area. In times past the German colonizers had set up diamond mining towns and what we see here is a decrepit washing plant in which diamonds were separated from the soil they were excavated from. The diamonds on the ground are since long gone but the ones in the skies above, remain.

Resolved in the sky we see clockwise, from the Pleiades Star Cluster to the Taurus asterism with its dust clouds, and on to the Witch head Nebula. The distinctive Orion Molecular complex with the Horsehead nebula and the Barnard’s loop take center stage.

The Seagull Nebula appears further right before we loop back to the Rosette and Christmas tree Nebula and onward to the Flaming star Nebula before completing the circle at the California Nebula. Whew!

Centaurus A: Extreme Deep Field - 321 Hours

This ultra-deep, high-resolution image of Centaurus A (NGC 5128) was created using data collected over ten years, from 2013 to 2024, with my homebuilt telescope. There are no stars in this image — every single point of light is either part of the Centaurus A system or a distant background galaxy or quasar!
This work is a continuation of my Centaurus A "Extreme Deep Field" project, now with a larger field of view (FOV) and significantly more data — 321 hours in total, including 126 hours of narrowband H-Alpha and OIII.

In 2013 I gathered 120 hours of data on Centaurus A and processed the then deepest image ever obtained of this magnificent galaxy, showing several structures not revealed by amateurs before. I updated and re-processed the image in 2014 and 2018, including adding H-Alpha data to highlight the impressive emission structures triggered by the relativistic jet from the supermassive central black hole. This current image is a major update, now just over 10 years after my initial ultra-deep image was completed.

Several unique features are visible:
The full extent of H-Alpha and OIII filaments associated with the relativistic black hole jets:
The inner and outer Northern (bottom) jet shows many faint details not previously imaged
The Southern (top) jet is visible as a small red blob in the 10 o'clock position (first detected optically in my earlier 2013 image)


The complete shell structure of the halo, showing both the faint outer shells and brighter inner ones
A distinct blue arc, a remnant stellar stream from a dwarf galaxy absorbed by Centaurus A
1108 of the known globular clusters orbiting the galaxy
Countless distant background galaxies and quasars
