Here is the continuation of my large summer-2018 project.

I had imaged this region for about 13 nights altogether between July and October 2018. You can call me crazy, using so many nights for just one object, in a region where clear nights are rare :) But I really wanted to see if I could catch this beautiful Supernova remnant, and I'm glad it succeeded :)

Recently Pixinsight was supplied with the new Starnet++ module, which you can use to completely separate the stars from the background. I used this software to enhance the very weak nebulosity and was astonished to see how much more could be drawn from the background compared to the processing I did last year. All other processing was performed using Astropixelprocessor and photoshop.

Supernova remnants (SNR) are formed when a large star ends its life in a supernova explosion. About 300 of these remnants are currently known in our galaxy. One of the most famous remnants, the Veil Nebula, is located in the constellation of Cygnus. Although this is the most famous one in this constellation, it’s not the only SNR. Cygnus contains several obscure SNR’s, among which SNR 65.3+5.7 (also known as SNR 65.2+5.7).

SNR G65.3+5.7 was discovered by Gull et al. (1977) during an OIII survey of the Milky Way. Some parts of this SNR were already catalogued by Stewart Sharpless in his SH2 catalog as SH2-91, SH2-94 and SH2-96, but they were not recognized as being part of a bigger structure at that time. The idea that they could be part of a larger SNR was postulated by Sidney van den Bergh in 1960, but it took until 1977 for this to be confirmed.

This is one of the larger SNR in the sky spanning a region of roughly 4.0x3.3 degrees. Mavromatakis et al. (2002) determined the age of the SNR to be 20.000-25.000 years and the distance about 2.600 – 3.200 lightyears. The shell has a diameter of roughly 230 lightyears! This SNR is a predominantly OIII shell with also some H-alpha signal.

This supernova shell is quite weak and there are hardly any high-resolution images of this region. In the internet maybe 5-10 deep images of this shell can be found and, in most cases, they don’t cover the entire shell or the resolution is quite low because it was done by using photo lenses at short focal lengths. That’s why I decided to see if I could try to image the entire shell using my equipment, a TMB92 refractor in combination with a QSI583ws ccd camera. Because of its large size I needed to make a 3x3 mosaic to cover the whole region.

As so many nights were already necessary to cover the region in OIII I didn’t succeed in grabbing the H-alpha data, but on the internet I found the MDWsurvey (mdwskysurvey.org) initiated by David Mittelman (†), Dennis di Cicco, and Sean Walker (MDW). This is a marvelous project with the goal to image the entire northern sky in H-alpha at a resolution of 3.17”/pixel. I contacted them and told them of my effort to grab imagery of this SNR and they were very kind to provide me with the H-alpha imagery of this region, so that the entire SNR could be brought into view in reasonable high resolution.

This bicolor image shows a combination of about 53h of OIII data (made by myself) and 20 hours of Ha-data (made by the MDW survey) in a single image. In this way the full span of the shell can be seen in all its glory.

This image shows the extended nebulosity around IC59/IC63. This nebulosity is very rarely found on imagery, and as far as I know only a handful of images showing this nebulosity can be found, where most of them only show a very weak impression of the nebulosity. With this image I hope to challenge people to image this beautiful region and maybe even bring out more details. It's really worth it!

The image was processed with astropixelprocessor and after that the starnet++ script in pixinsight was used to separate the stars from the nebulosity. Using Niktools the nebulosity was sharpened and stretched to show more detail in the final image.

The Hercules Globular Cluster is composed of several hundred thousand stars and is about 24,000 light years away from Earth. The stars are so densely packed together they sometimes collide to form new stars called ‘blue stragglers’ which can clearly be seen in the image (zooming in helps!).

A globular cluster is a spherical collection of stars bound by gravity. Globular clusters in spiral galaxies like the Milky Way are found in the galactic halo which is the outer spheroidal part of the galaxy rather than found in the galaxy’s disc. Globular clusters tend to have older more massive stars and are composed of fewer heavy elements than open clusters. There are more than 150 Globular Clusters in the Milky Way. [Wikipedia]

Comet C/2023 P1 (Nishimura) September 3, 2023. This comet is bright enough to photograph with a small telescope and should be visible in binoculars (I didn't try until the sky was too bright so didn't see it), but not naked eye.

Comet 67P/Churyumov-Gerasimenko passes through the constellation Gemini on three consecutive nights: November 6, 7, and 8, 2021 (right to left), near the closest it will come to the Earth in its orbit. This is the brightest comet in the sky right now, though still not really very bright at all. ESA's Rosetta spacecraft orbited Comet 67P and the Phillae probe landed on it back in 2014. The orange-ish star at upper right is upsilon Geminorum, one of the bright stars in Gemini.

This is a composite of multiple exposures taken over several hours on each of the three nights. These were combined to produce a panoramic view of the background and of the comet on each night.

The Hyades star cluster is the head of the bull in the Taurus constellation; Aldebaran, the brightest yellow star, is the eye. Quite a few dark nebulae are also present in this extent, as well as star cluster NGC 1647 in the upper left.

I normally wouldn't have astrophotographed on a night forecast to have only a small window of clear skies, but it had been a couple months since I had been able to image, so I went for it. I only managed 20 minutes of data without high, thin cloud cover despite shooting for well over an hour, but you have to take what you can get during winter in north Idaho. I'm going to shoot this one again sometime.

M 81 and M 82 are truly „iconic“ deep sky objects! I spent more than 17 hours on capturing this widefield, comprising „Bode’s Galaxy“, the „Cigar Galaxy“, some smaller galaxies nearby (like NGC 3077 and NGC 2976) and the galactical cirrus, that consists of dust within our own galaxy's disk.

To create a picture from RGB, H-Alpha and Luminance data and keep the balance between both, the bright galaxies and the faint cirrus, was a real challenge and took me many, many hours. Hope you like it!

Easily the largest Seagull ever seen, by light years ;-)

The Seagull Nebula (Sh2-296) lies just on the border between the constellations of Monoceros (The Unicorn) and Canis Major (The Great Dog) and is close to Sirius, the brightest star in the night sky. The nebula lies more than four hundred times further away than the famous star.

The complex of gas and dust that forms the head of the seagull glows brightly in the sky due to the strong ultraviolet radiation coming mostly from one brilliant young star HD 53367.

The radiation from the young stars causes the surrounding hydrogen gas to glow. Light from the hot blue-white stars is also scattered off the tiny dust particles in the nebula to create a contrasting blue haze in some parts of the picture.

Spanning about 100 light-years from one wingtip to the other, Sh2-296 displays glowing material and dark dust lanes weaving amid bright stars.

It is a beautiful example of an emission nebula, in this case an HII region, indicating active formation of new stars, which can be seen peppering this image.

The Seagull Nebula complex was observed for the first time by the German-British astronomer Sir William Herschel back in 1785.

SHO Taken between 22 and 27 February 2022 (65% - 13% Moon), RGB stars taken 7 March 2022 (22% Moon). Last chance to capture this target for me in my location for 2022, but also my first attempt. I could have squeezed in Thor’s Helmet if I had rotated the camera but I didn’t want to change the optics at this point. I could only manage 2.5 hours a night due to the target getting lower by this time of year, and crashing into a neighbours tree.

I spent far too many hours processing and reprocessing using new and different Pixinsight work flows to get the best from the data, and of course I would like to start over again, but time to let this big bird free until I capture it again next time around.

With one of the more spectacular views in the night sky, Thor's Helmet Nebula (NGC 2359) features a bubble shaped emission nebula. This bubble (containing hundreds of solar masses of ionized material) appears to be getting blown by solar wind coming from the central star. This is a rare type of central star known as a Wolf-Rayet star which runs extremely hot and is thought to be in a pre-supernova stage.

Calibrated images of Thor's Helmet Nebula were provided by iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them.

I wanted to include the Perseus molecular cloud in the same extent as the California Nebula, but it didn't quite fit in the 1.5x-crop-factor field of view of my Fuji + Samyang 135mm lens, so I shot a mosaic of 4 panels. I thought snct astro did a great job framing the extent here (flic.kr/p/2kcoAZu), so I imitated their framing.

Panels were 26, 30, 22, and 37 x 1 min integrations and overlapped substantially, so most areas were covered by more than one panel. I also added 50 x 1 min of imagery of the Perseus Molecular Cloud from Nov. 20, 2019 (flic.kr/p/2hNZ6iA). So in total this is 165 minutes worth of data.

Perchée à près de 1000 mètres d’altitude (913 mètres exactement), la majestueuse Tour de Peyrebrune veille fièrement sur les contreforts du Lévézou. Nichée au sommet d'Alrance, elle offre une vue imprenable sur le lac de Panat, dans un cadre naturel à couper le souffle. Jadis, au Moyen Âge, cet endroit abritait un château fort et un ensemble de fortifications, témoins d’un passé riche en histoire.

Mon objectif était simple : jamais je n’avais vu de photo de la tour prise en astrophoto, un vide qu’il me fallait impérativement combler. La plus grande difficulté résidait dans la recherche du point de vue parfait, suffisamment dégagé pour laisser apparaître, sous un ciel étoilé, Orion, les Pléiades et la splendide nébuleuse de la Californie.
