SH 2-240 Spaghetti nebula IC 405 Flaming star nebula

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. Now I tried a focal length of 414 mm and an APS-C sensor, to frame it. I photographed this nebula for two nights, the total integration time is nearly 11 hours.

And here are the stars processed out:

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):

I am back home from Namibia, so I took the opportunity of a cloudless, moonless night to take my big Newtonian for a spin. The most prominent summer deep space object is obviously the Eagle nebula, so I pointed the telescope in the constellation Serpens and photographed this DSO whole night long. In total, I captured 64 images, each 5 minutes long.

NGC 6188 is sometimes called The Fighting Dragons of Ara. As a fan of Game of Thrones or Hobit, I simply had to capture this beauty. Two dragons are clearly visible in the middle. Their heads are illuminated by the open cluster NGC 6193. I knew that this nebula is dim, so I dedicated a lot of time to it. Specifically, I stacked 86 narrow band pictures, each 5 minutes long.

Cat's Paw nebula DSO HII region Kiripotib Lobster nebula Namibia Nebula NGC 6357 NGC6334 Rainbow Astro RST135 Scorpius Sharpstar 94EDPH ZWO ASI 2600MM

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.

The composition of this picture was not correctly selected, but in the end, both are in the field of view. Here is the picture processed in the “fake” Hubble palette:

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 ,’-)

IC 4628, also called Prawn Nebula is an HII region in the constellation Scorpius. Due to very low southern declination, it is poorly visible even from southern Europe. The southern hemisphere is obviously a better place to observe/photograph this deep-space object for example in Namibia, where this beautiful nebula rises very high in the sky. The open cluster on the left side is called the Northern Juwel box cluster.

IC 2944 Running Chicken Nebula is an H II region located in the constellation Centaurus. It’s a galactic neighbor of the Carina Nebula because they both belong to the Sagittarius spiral arm of the Milky Way Galaxy. 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.

And here is an even more “fake” picture, where the stars are completely removed. However, the nebulosity gained a 3D-like look.

Carina Carina nebula DSO Eta Carinae Great Carina Nebula Kiripotib Namibia Narrow band Nebula NGC 3372 NGC3372 Rainbow Astro RST135 Sharpstar 94EDPH ZWO ASI 2600MM

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.

The Cone Nebula is a molecular cloud of excited hydrogen gas, located in the constellation Monoceros. It belongs to the group of nebulae, which can be observed/photographed during the winter in the northern hemisphere. I tried to capture this object a long time ago without success. I must say, it’s a very difficult one, so I attempted this time with new equipment. Specifically new extra, super, mega narrowband filters, having a bandwidth of only 3 nm. Combined with a small 6″ Newtonian telescope I was able to generate a pretty decent picture.

Another nebula, which resembles a head of an animal is designated NGC 2174, sometimes called Monkey Head Nebula. After capturing the Horse Head Nebula in the constellation Orion, I waited for a few days for good weather and pointed my telescope again into the Orion, this time to its northern part. Monkey Head Nebula is an HII region, which is approximately 6400 light-years away from Earth. To find a monkey is not that difficult. There is a baboon’s head on the upper left side, which is looking into the constellation Taurus.

The best way to capture this nebula is by using narrowband filters. For this purpose, I ordered a new monochrome camera ZWO 2600MM with a 2″ filter wheel. The filters are equally important as a camera, so I decided on Antlia 3 nm. As a first light, I must say that this combination works really well. I made in total 90 exposures, 5 minutes each, which means over 7 hours of integration time.

Horsehead nebula is IMHO the most beautiful deep space object. It is located in the constellation Orion. Everybody knows this constellation because it can be easily identified by three aligned stars (Alnitak, Alnilam, and Mintaka), which forms the belt of the Orion.

The nebula is very dim. Therefore, visual observation is nearly impossible, unless you have a telescope, having at least 1 meter in diameter. To photograph it, one needs a very long exposure time. I used 5 minutes per image and I took 36 of them. The nebula complex is visually very large, so the optimal focal length should be shorter than 750 mm. I used a Newtonian telescope with a focal length of 1000 mm but reduced to 750 mm by the Nexus coma corrector. It turns the Newtonian into a light-collecting bucket, but the quality suffers from that. The stars in the corners are everything, but round. Moreover, I used dual-band filter Optolong L-eXtreme, which increased the contrast of the nebula, but also made the asymmetric halo around the bright stars. I played a bit with the white balance and pushed the colors into the orange tint, to reach the warmer feeling in cold February.

Jellyfish Nebula is a supernova remnant in the constellation Gemini. A very long time ago a supermassive star exploded and emitted a lot of material into space. It is not clear when exactly it happened, but the latest research dates the explosion between a few thousand years and 30’000 years. The shape definitely resembles a jellyfish, having the head at the top and tentacles at the bottom and overall it looks like it floats in the space. It’s interesting how many nebulae have names related to an animal. For example the Seagull Nebula, the Elephant Trunk Nebula, the Eagle Nebula, the Lobster Nebula, the Horsehead Nebula, etc.

California Nebula is a cloud of ionized hydrogen gas (HII region), which can be found in the constellation Perseus. The nebula is 1320 light-years away from Earth and it is 100 light-years long. Visual observation is very difficult, due to very low brightness. The first person who spotted this nebula was Edward Emerson Barnard in 1885. Since it is an emission nebula, it can be relatively easily photographed even under the light-polluted sky, with help of a narrowband filter.

I always wanted to capture this nebula, but the focal length must be relatively short. This is a perfect opportunity to test the William Optics RedCat. This time not with Canon EOS 6Da, but I attached a cooled astro camera ZWO ASI071 and placed the Optolong L-eXtreme dual-band filter.

I have a new toy. Motivated by a quite bad experience with ASKAR 180 FMA and its chromatic aberration I started to search for a better pocket-size telescope. To decide which one was quite simple. I would say there is nothing sharper and nothing with a better reputation than William Optics RedCat 51mm. The detailed comparison with ASKAR will come a bit later. This is the first light, where I tested the portable setup – iOptron Skyguider on a tripod, Canon 6Da, and the RedCat. The Moon was shining like crazy, therefore I attached the dual narrow band filter Optolong L-eXtreme filter. After 3 hours of collecting the filtrated photons, a pretty nice picture came out of it. I took this DSO using the same camera combined with the ASKAR 180FMA (link) but in broadband. Therefore, it’s like comparing apples and oranges. However, the RedCat looks much sharper and it contains more details. I cannot wait to test the RedCat under dark skies.

I couldn’t imagine a better final object for the winter season. Rosette Nebula is my favorite H II region in the constellation Monoceros. At the same time, I used this deep-space object to test my portable Newtonian telescope with my new monochromatic camera ZWO ASI 2600MM. Well compared to the previous setup, this camera has much smaller pixels, which increases the requirements for the optics, specifically for the coma corrector. I am not happy with the star shape and for my planned trip to Namibia, I will try to find a portable refractor.
