This is data from Oct 29, 2022. I created two videos to show the workflow of pre and post processing the same dataset using Sirilic/Siril and AstroPixelProcessor. The image in this shot was done through APP. Slight adjustments in Photoshop but if you look at the end of the video, the edits are pretty miniscule because I wanted to do some noise reduction (since APP doesn't have one).

The Wizard Nebula is an emission nebula that surrounds the open star cluster NGC 7380 in the constellation Cepheus. The nebula is known for its unique shape, resembling the appearance of a medieval sorcerer. The active star forming region lies at a distance of 7,200 light years from Earth and has an apparent magnitude of 7.2. It has a radius of 100 light years and occupies 25 arc minutes of the apparent sky. It has the designation Sh2-142 in the Sharpless catalog of H II regions.

Taken 23 June 2020 and 8,9,10 July 2020. Moon was minimal, early setting and low in the sky on these dates.

I was having trouble with movement in the optical train, now fixed with a better focuser, so framing not so good as I didn’t want to rotate the camera and filter wheel to one side. Will do next time around. Also, my focal length has walked during collimation so focus is not optimal and focal plane is tilted. Currently working on that issue to optimise the whole setup. Will invest in a Howie Glater laser collimator to help with that.

Several LDNs and LBNs (LBN 133 & 134, LDN 768, 769, 772, 773, 774, 775, 779) in the constellation Vulpecula form the dark nebula structures that stand out against a carpet of stars and resemble the shape of the "Monster of Loch Ness." Additionally, there are two beautiful reflection nebulae in the area. This object was the perfect target for a moonless, short summer night, combined with the RASA 8 telescope at f/2.

During the editing process, I tried to bring out the delicate structures in the dark nebulae, avoiding creating a nearly completely black area. Moreover, I aimed to preserve and enhance the color variety not only among the larger stars but also among the countless smaller ones to achieve greater depth. I hope you like it!

The red emission Nebula called Cygnus Wall is the part of the North America Nebula (NGC7000) that resembles Mexico/Central America. The region is characterized by dark nebulas and dust lanes that give the scenery a dramatic attitude.

The image was made with a standard unmodified Pentax K3ii on a TS 130/910 refractor with 0.79x reducer. The blue/ red colors were generated by separating magenta and red in postprocessing and shifting the magenta more and more to light blue. The now blue colors should represent OIII emission regions while the red colors come from Hydrogen alpha emissions.

The Great Orion Nebula is an enormous cloud of dust and gas where large numbers of new stars are being formed. It's bright central region, the Trapezium cluster, is home to four massive young stars that help shape the nebula.

Orion is estimated to be around 24 light years across and has a mass of about 2,000 times that of our Sun. It lies about 1,350 light years away from Earth.

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.

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.

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.

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]

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. Itelescope.net captured the images and I did the post-processing with Astro Pixel Processor, Photoshop and Topaz Sharpen AI. Star spikes are natural.

Sh2-132, also known as the "Lion Nebula", is an emission nebula located in the constellation Cepheus. Part of the Sharpless catalog, a list ofH II regions - clouds of glowing gas where star formation occurs.

About 10,000ly distant and 250ly across, Sh2-132 is situated in the Perseus arm of the Milky Way.

The most prominent sources of ionization in Sh2-132 are two Wolf-Rayet stars, which are extremely hot and massive stars nearing the end of their lives. These stars emit intense stellar winds shaping the surrounding gas into intricate structures.

Another of those occasions where one tries to match the DSS image of the Ha emission pattern resembling a lion with how the data looks. Make the OIII too bright a blue and it becomes a cut-'n'-shut with the front and rear ends too separate... It's also about the fine veins and blobs of dark nebulae - lanes of dust in the foreground.

4hr35min total integration with the IDAS NBZ dual-narrowband (Ha + OIII) filter, from which I extracted the Ha & OIII data separately using APP and recombined in PI.
