IC5146 Cocoon Nebula

IC5146, sometimes called Cocoon Nebula, is an emissive nebula located in constellation Cygnus. Central star in the nebula is responsible for the excitation of the surrounding hydrogen gas. On the picture is also captured dark nebula Barnard 168, which creates the strip and it looks like the Cocoon Nebula has a tail.

NGC7293 Helix Nebula

NGC 7293, sometimes called Helix Nebula, is the closest planetary nebula (only 700 light-years away), which can be located in constellation Aquarius. Last year I captured this nebula on Gavdos. This year on Milos I was equipped by different telescope and different camera, so I gave it a try again.

IC1396 Elephant’s Trunk nebula

IC 1396 is a mixture of ionized interstellar gas and dust cloud located in the constellation Cepheus, approximately 2’400 light-years from earth. Due to relative proximity of the nebula, it didn’t fit into the field of view of my telescope/camera. My previous picture, which I captured by the same telescope, was created by using focal reducer and therefore nearly fit into the field of view of even smaller CCD chip. However, under dark skies of Milos, there is no need to use narrow band filters and very nice dark nebulae are nicely visible.

NGC 6888 Crescent Nebula

Crescent Nebula, also known as NGC 6888, is a HII region, hot ionized hydrogen gas cloud. The nebula got the shape by high speed stellar wind of Wolf-Rayet star, which is colliding with slow moving mass, ejected by this star during transformation into a red giant. The nebula is approximately 5000 light-years away from us and it can be located in constellation Cygnus.

The picture is the last one from 6.9.2018. In the evening I captured Omega nebula, M80. As a last deep space object I pointed on Crescent Nebula, started auto guiding and went to sleep. Therefore the picture is a stack of 64 pictures; each has 3 minutes of exposure time, thus total integration time 192 minutes.

IC 1318 Butterfly Nebula, Barnard 347

IC 1318 is an emission nebula, sometimes called Sadr region, located in constellation Cygnus, surrounding bright star Sadr. The star Sadr didn’t fit into the field view of my telescope/camera, but left the trace in form of diffraction spike at the top of the picture. The nebula contains many dark nebulae and the biggest in the middle of the picture is called Barnard 347.

The picture is another demonstration of dark skies of Milos and it is an integration of 77 pictures, each 3 minutes exposure, which means nearly 4 hours of integration time.

M8 Lagoon Nebula

Lagoon nebula (sometimes called Messier 8) is a giant intergalactic cloud of ionized Hydrogen. The nebula is located in constellation Sagittarius and it’s 4100 light-years away from Solar System. It belongs to one of the brightest nebulas visible from northern hemisphere.

I have to admit, this nebula was the main reason and target of the trip to Milos and it was the first deep space object captured there. When I processed the picture I was so happy that the nebulosity is so clearly visible without any narrow band filters. Well, mission accomplished.

NGC281 Pacman nebula

NGC281 is a HII region, which reminds a head of the main character in very popular game from nineties. It is located in constellation Cassiopeia and it 9500 light-year far from us. This nebula was discovered long time ago by Edward Emerson Barnard and it is possible to observe this nebula by reasonable sized telescope under dark skies. Well, I wouldn’t see probably anything, because I live in light polluted area, therefore I had to use narrow band filters, which block the light pollution.

The picture is composed out of 66 narrow band exposures, which means slightly more than one hour per channel. First one is bi-color composition of hydrogen and oxygen, the others are in Hubble palette (hydrogen in green, oxygen in blue and sulfur in red).

IC1848 Soul nebula

Soul nebula is a beautiful HII region, where new stars are being born. It’s located in constellation Cassiopeia and it’s 7500 light-years from Earth. The nebula has neighbor Heart Nebula (IC1805). One can say that in this constellation the heart and soul are close to each other.

As usual, I used narrow band filters to capture this spectacular nebula. It didn’t fit into ma field of view; this means I would need shorter focal length.

IC5070 Pelican nebula

Pelican nebula is large cloud of hydrogen gas, where many stars are being born, located in constellation Cygnus (Swan). The nebula is approximately 2000 light-years away from Earth. If you use bit of an imagination, you will be able to see the pelican in the dark cloud surrounding the brighter center of the nebula – good luck with searching.

The picture was taken completely by narrow band filters. The first one is in “fake” Hubble palette and second one as a bi-color image (Ha in red channel, OIII in green and blue channel).

IC1396 Elephant trunk nebula

Elephant trunk nebula is visually one of the biggest deep space objects in the sky. It covers more than 6 times the diameter of the Moon. I had to use the telescope with the shortest focal length and use focal reducer ASA 0.73. Recently, I managed to improve the picture quality of this reducer by adjustment of the tilt. The nebula can be located in constellation Cepheus, but it cannot be spotted visually because it’s very dim.

I spent 4 nights capturing these photos. In total, there is nearly 19 hours of exposure time. Probably this is my longest integration time I have ever made. The first picture is in fake Hubble colors, second one in more or less visible spectrum colors.

M20 Trifid nebula

Trifid nebula is a combination of emission, reflection and dark nebula – pretty unique. It got its name from 3 dark lines across emission (red) part. The lines are dust clouds blocking the light emitted by ionized hydrogen.  It’s possible to observe this nebula, but one needs dark skies and a telescope with aperture at least 120 mm. The nebula can be found in constellation Sagittarius and it’s 5200 light-years far from Earth.

The picture was taken in Gavdos during my first dark sky chasing. The total integration time is only one hour, which is remarkable for such portable setup.

M27 Dumbbell nebula

Here comes another comparison between two cameras, telescopes and mounts. ZWO 1600 MC competes with Moravian G2 8300. Ritchey-Chrétien 154 mm competes with Newton 254mm f4 and Gemini G53f is challenged by iOptron CEM25P. I know it is incomparable aperture, price and portability, moreover the integration time is in favour of Newton, but I am very positively surprised by the outcome of the portable setup (ZWO, RC, iOptron). The nebula is logically better captured by the Newton, but RC telescope has definitely more regular star shapes (except the corners, there is quality quite poor).

Brief description of the Dumbbell nebula is here. Upper picture was made by heavy equipment (MII G2, Newton 254mm and Gemini G53f) and the lower picture was captured by portable setup (ZWO, RC 154 and iOptron).

NGC2264 Cone nebula

Cone nebula is a giant cloud of ionized hydrogen gas, which includes the Christmas Tree Cluster. It’s located between two bright winter stars Betelgeuse (constellation Orion) and Procyon (Canis Minor) and it’s 2700 light-years far from the Solar System. There is a famous picture from Hubble Space telescope of the tip of the cone – star forming complex.

Bi-color picture didn’t look as I expected, therefore I decided to publish only mono version of hydrogen alpha channel.


M42 Great nebula in Orion

I don’t want to repeat myself, therefore the description on the most famous nebula visible from northern hemisphere can be found here.

The previous picture has some strange halo around the bright Hatsya star and I was thinking why. Recently similar picture came out of my telescope and I realized that this strange halo is caused by the frost on the secondary mirror. I manufacture home-made dew shield and I don’t have these problems anymore.

This picture is, as usual, composed out of narrow band pictures. When I look at it I am still not happy, therefore I hope next year will be better weather and I will make a better picture.


M1 Crab nebula

It all started here. Crab nebula is the first catalogued deep space object. Charles Messier was searching for the comet (1758) but discovered his first deep space object. Crab nebula, also called Messier 1, is a supernova remnant – something like Veil nebula, but it’s much further from the Solar system – 6500 light years.

My first picture was made with pinched mirror, therefore I waited two years and captured it properly. Since I live in light polluted area, I chose narrow band filters, in order to get better contrast and composed this picture out of hydrogen alpha (red channel) and OIII (green and blue channel) narrow band pictures.


IC59 IC63 Gama Cassiopeia nebula

Is a reflection nebula located in constellation Cassiopeia, approximately 600 light years from Solar System. This nebula is very dim, therefore I used narrow band filters Ha, OIII and SII and composed two pictures. One is composed in real colors, second in fake (Hubble) color palette.


NGC6992 Veil nebula

The mostly photographed deep space object by me is Veil nebula. I simply love this supernova remnant. Previous mosaic picture revealed that the eastern part is slightly brighter, therefore I pointed my telescope with longer focal length there and made this bi-color picture.


NGC7380 Wizard nebula

Wizard nebula is an open cluster associated with nebulosity.  Visually, it has apparent size of the full Moon, but since it’s very far from the Earth (7200 light years), its real diameter is about 100 light years.

So, where is the wizard located? It took me a while to find him, but if you turn your head 90° counter-clockwise, you see two darker hands. It looks like he is trying to grab something. Then above the hands you see the wizard’s conical hat.

First picture is a composition of 3 narrow band pictures (Ha, OIII and SII) and composed in Hubble Space Telescope palette. Second one is more-or less visible spectrum.

NGC6960 NGC6992 Veil nebula mosaic

Here is another picture of my favorite Veil nebula. First attempt here with long focal length (1000 mm), second attempt here with shorter focal length (730 mm) and finally third here with the shortest focal length I have (430 mm). Still I haven’t captured everything of the nebula last year and this year I focused my smallest telescope to the western part of the Veil nebula and created mosaic.

The picture, as well as the previous ones is bi-color images. I captured hydrogen alpha (Ha) and oxygen III (OIII) narrow band images and inserted Ha image into the red channel and OIII into green and blue channel.

NGC6820 Nebula

NGC6820 Nebula doesn’t have a name, so let’s call it Hidden octopus nebula (because only one tentacle is visible). Hidden octopus nebula is a giant cloud (50 light years in diameter) of ionized hydrogen alpha gas, where new stars are born. The tentacle forms similar structure just like in more famous M16 Eagle nebula. It’s located in constellation Vulpecula (Little fox) not far from M27 Dumbbell nebula and it’s 6000 light year from Earth.

The picture was processed in bi-color technique. This means: two narrow band pictures, one H alpha and OIII. H alpha inserted into the red channel, OIII into the green and blue one.
