The Vela Supernova Remnant Nebula emerged from the explosive demise of a massive star, scattering its outer layers across space. Filamentary structures, shaped by shockwaves and magnetic fields, intertwine throughout the nebula, painting an intricate cosmic tapestry.

Radiating vibrant hues of red, green, and blue, the nebula’s ionized gases create a stunning visual display. Observations reveal delicate wisps of gas, shock fronts, and remnants of the original star, including a pulsar emitting electromagnetic radiation.

The Vela Supernova Remnant Nebula showcases the grandeur of stellar cataclysms. Its intricate structure and vibrant colors captivate observers, urging us to ponder the forces that shape our universe. Explore this cosmic masterpiece and unlock the mysteries of our celestial past.

I had to revisit this deep-space object with a much shorter focal length and a much bigger CMOS sensor. Last year it simply didn’t fit in the field of view.

Leo triplet is a group of galaxies in the constellation Leo. It contains galaxies NGC 3628 (upper left), Messier 65 (upper right), and Messier 66 (middle down). These galaxies are visible nicely in spring when the constellation Leo rises in the southern part of the sky.

I captured the picture shown here last year, but I haven’t had time to process it so far. It is interesting to compare the progress I made in astrophotography in the last few years. I made the very first picture of this group of galaxies in 2015 and for the first time, I used Pixinsight software for post-processing. The improvement over the freeware Deep Space Stacker was enormous. Similar boost I got recently when I installed BlurXterminator (Pixinsight plugin), which significantly improved the sharpness, but without any unrealistic artifacts.

Messier 63 is a stunning spiral galaxy located about 37 million light-years away from Earth in the constellation Canes Venatici. The galaxy gets its name from the striking pattern of dust and gas that resembles the petals of a sunflower surrounding its bright yellow core.

The Sunflower Galaxy was first discovered by the French astronomer Pierre Méchain in 1779 and later added to the Messier catalog by Charles Messier in 1781. With an apparent magnitude of 8.6, it is easily visible with a small telescope or binoculars.

Spring is a great time to observe galaxies like Messier 63 because, during this season, the Earth is oriented in such a way that we are looking out towards the outer regions of our Milky Way galaxy. This means that the sky is darker and clearer, providing ideal conditions for observing distant galaxies.

Antlia Dualband High speed filter Auriga DSO Elnath Flaming star nebula HII region iOptron Skyguider Pro Nebula Samyang 135 f2 SH 2-229 SH 2-240 Spaghetti nebula Supernova remnant Taurus ZWO ASI6200MC

The Spaghetti nebula (upper left corner) is a supernova remnant. This means, roughly 40’000 years ago, there was a massive star in the middle of the spherical conglomerate of filaments. The star ended its life in a spectacular explosion and turned into a new form – a pulsar. I knew from the beginning, that I would be chasing the ghost. Cosmic Spaghetti are a very dim nebula and to capture them one needs a wide-angle telescope, fast optics, narrow band filter, and a lot of patience. I didn’t use a telescope, but a lens Samyang 135 mm f 2.0 slowed down to f 2.8, combined with a brand new dual-narrow band Antlia filter, optimized for high-speed optics, and in total, I collected the photons for nearly 10 hours.

The much brighter nebula in the bottom right corner is called Flaming Star Nebula, cataloged under IC 405. Compared to the Spaghetti Nebula, which represents the death of the star, the Flaming Star Nebula represents the vital part of the life of the star AE Aurigae. This star radiates so strongly, that it excites surrounding hydrogen gas. Therefore it is called an emission nebula.

Visually not far away, the comet C/2022 E3 ZTF was passing around Mars, but I was not distracted by that, because I was concentrating to capture as many pictures of the Spaghetti as possible. Besides, I already captured this comet recently.

Elephant Trunk Nebula is my favorite nebula in the constellation Cepheus. I photographed it many times using many different telescopes. The focal length was either too short or too long.

The Crescent nebula is an HII region in the constellation Cygnus. I photographed this deep-space object before with a relatively long focal length. The Crescent nebula is not the only nebula in the constellation Cygnus. In fact, this constellation is overpopulated with either emission or planetary nebulae. This is the reason why I picked a shorter focal length than before (wider field of view), positioned the Crescent nebula in the corner of the CMOS chip, and let the photos be collected for 3 subsequent nights. In total, I exposed 153 photos, each 5 minutes long. This means nearly 13 hours of integration time, which makes it one of the longest total exposure I spent on a single deep-space image.

I am back from a very intensive trip to Namibia. The report is still pending because I post-processed the data the whole summer. Please stay tuned. Anyway, a few days in August was nice weather, so I took the SharpStar 94 EPDH telescope and pointed into the constellation Cygnus. There are many deep-space objects in this constellation because it is on the galactic plane. Probably the brightest and the most spectacular is North Americal Nebula, sometimes called the Cygnus wall. Since I live in a light-polluted area, I used narrow-band filters to create this image, which is a combination of Hydrogen-alpha (Ha) in the green channel, oxygen III (OIII) in the blue channel, and sulfur II (SII) in the red channel.

And here is a simplified bi-color variant (red – Ha, green OIII, blue OIII):

Both Lobster and Cat’s Pas nebulae are located in the constellation Scorpius, both are approximately 5’500 light-years from us. I tried to photograph the Lobster Nebula before, but it wasn’t an easy target due to very low southern declination. From the southern hemisphere, it is much easier. So I took the opportunity when I was in Namibia and tried to capture both nebulae in one shot.

Supernova Remnant in the southern constellation Vela is the closest remnant to Earth. It is “only” 800 light years away from us and it has a diameter of 100 light years. This is the reason why this deep space object didn’t fit in the field of view of my portable 250 mm focal length RedCat.

The initial plan was to make a panorama of two pictures, but the pictures are not perfectly aligned. At least I have one more reason to come back to Namibia ,’-)

I must admit that this was my secondary nebula target for my trip to Namibia. Therefore, I didn’t dedicate much time – only 3 hours. However, the details popped out, so overall, I am happy with this “fake” Hubble palette picture.

Messier 83, sometimes called Southern Pinwheel Galaxy is one of the most difficult deep space objects in the whole of Messier’s catalog. It is located between the constellations Hydra and Centaurus. This galaxy has a very low southern declination (close to the horizon) and this makes it difficult to photograph in Central Europe. I tried a few years ago in La Palma, but my attempt was ruined by clouds and bad weather in general. This time I was better prepared: traveled south and hired a telescope with a much longer focal length. However, after the acquisition in the post-processing stage, I noticed that the final image is not that sharp and it was not really publishable. I was quite disappointed and put the picture in the archive. Recently I came back to this image because a new tool for sharpening was released – BlurXTerminator. I must say, this plugin for Pixinsight makes magical things. It reduces the stars and simultaneously makes the non-stellar object significantly sharper. I managed to turn an unfocused picture into this:

Eta Carina Nebula is the southern hemisphere’s most prominent deep space object. In fact, this nebula is the reason why I packed all my portable astro-gear and flew to Namibia. Carina is approximately 4x brighter than the Orion nebula, which could be considered a highlight of the northern hemisphere. Moreover, it’s much larger. The nebula is a combination of emission and dark nebulae, located in the constellation Carina and it’s roughly 8500 light-years away from us.

It was a struggle to get the rig working in Namibia, but after two nights I managed and the next day, when I processed the pictures, a big smile appeared on my face. Well done, mission accomplished.

During our stay at Kiripotib Namibia, the other guest rented a 14.5-inch Dobsonian telescope and allowed us to have a look at the Carina (thank you so much, Peter). It was a simply spectacular view. Such a huge aperture combined with TeleVue eyepieces – WOW effect was there. Moreover, the Dobsonian had a filter wheel with OIII, UHC, and H-beta filters. Just by turning it, one could see a completely different nebulosity. I was really happy to see this beautiful deep space object with my own eyes.
