A new image, the Witch's Broom Nebula
This is my second photo for this season from my observatory. It's a detail of the veil nebula supernova remnant, as was my first light photo for this Autumn season, the Pickering's Triangle. This is a two frames mosaic image, exposed on several nights between September 10. - 27. 2015. Total exposure time is about 11h.

Three experimental starless Oxygen emission images of the Veil nebula
I played with my older material, since the weather doesn't allow new projects.
This time I'm publishing three images of light emitted by an ionized Oxygen, O-III.
Images are closeups from the large supernova remnant in a constellation Cygnus, the Veil Nebula.
I wanted to see and show the actual structure of the nebula, due to that, stars are removed from each image.

Pickering's Triangle in Ha/OIII light
A somehow clear night for a long time!
Last night I was able to shoot O-III light (Light emitted by ionized oxygen.) for my latest project, the Pickering's Triangle in the Veil Nebula. I manged to collect three hours of O-III light, ones again clouds ruined about two hours of exposures. I'll shoot the S-II channel (Light emitted by ionized Sulfur.), as soon as the weather supports, for a three channel color image.
The Pickering's Triangle
A detail in the Veil Nebula supernova remnant
Two color image from H-a and O-III, image is in natural colors from narrowband channels. Emission of hydrogen can be seen as Red and emission of oxygen as Blue.
Pickering's Triangle is a small part of the Veil Nebula supernova remnant in constellation Cygnus.
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field.

Filaments of the Veil nebula, starless view
One of my starless astronomical image experiences, the Pickering's Triangle in Cygnus supernova remnant.
This area of the nebula is filled with colorful filaments, ionized sulfur and hydrogen are seen as green, golden hues, ionized oxygen can be seen as blue.
The complexity of filaments stands out nicely in this starless image.

Filaments of Veil in mapped colors
I shot most of the lights for this image back in 2016, now I have added some new material to it and reprocessed the whole image. A version in visual color palette can be seen here, https://astroanarchy.blogspot.com/2021/09/filaments-of-veil-nebula-snr.html
Photo was shot with a Celestron Edge HD 11" telescope, Astrodon naarrow band filters and Apogee Alta U16 astro camera. New data is shot with a shorter focal length instrument, Tokina AT-x 300mm f2.8 camera lens, same camera and filters. Dim background emission is taken from a new material and added to this photo.
Total exposure time is now 44 hours for the whole three frame mosaic and the resolution is 11.000 x 4000 pixels.

INFO
Since all of the heavier elements are born in exploding stars, we all are children of supernovae. Veil Nebula is located in the constellation Cygnus at a distance of 1500 light-years. It spans three degrees of sky, (Moon has an angular diameter of 0,5 degrees at the sky) real diameter is around 70 light-years. I collected data for the photo between 2012-2020 and I made this 3D model in 2021,exposure time is 45 hours

3D-study of Veil Nebula Photo
Every single pixel in this 3d-animation is from the original 2D-image above. The model is based on on known scientific facts, deduction and some artistic creativity. The result is an appraised simulation of reality. Astronomical photos are showing objects as paintings on a canvas, totally flat. In reality, they are three dimensional forms floating in three dimensional space. The purpose of my 3d-experiments is to show that and Give an idea, how those distant objects might look in reality.

Astro Anarchy, the year 2016
HAPPY NEW YEAR
This post is about all of my astronomical photos from the Autumn season of the year 2016
All my photos from the Spring and Autumn seasons of 2016 are taken with my new imaging setup. Celestron Edge HD 1100 with 0.7 reducer at 10-micron mount. Apogee Alta U16 camera with Astrodon filters and an active optics unit, SXV AO LF, from Starlight Xpress.
My humble thanks to the supporters, they made my work possible!

Filaments of the Veil Nebula
At this Autumn season I have shot several well known targets in constellation Cygnus.
My purpose was show them little differently by selecting some less imaged details to show.
This new image is a four panel mosaic showing the complex, filament like, structures in Veil Nebula supernova remnant. Original full resolution photo is about 11.000 x 4000 pixels! Total exposure time is around 35 hours. The final photo looks like a giant alien space plant...
