M23 Open Cluster

Messier 23 is an open cluster located in constellation Sagittarius not far from the star Polis (µ Sgr). Visually it’s surrounded in rich star field, because in this direction are located star clouds of Milky Way. The cluster contains approximately 150 confirmed members and it’s about 2000 light-years away from the Solar System.

M20 Trifid Nebula M21 Open Cluster

Messier 20 (called Trifid Nebula) has been captured by me already on Gavdos. This year I had a telescope with shorter focal length, therefore I managed to capture two objects of Messier’s catalogue on one shot. Specifically it’s mentioned Trifid Nebula and M21 Open Cluster (down left from the nebula). The nebula has been already described in my previous post and it’s located not far from M8 Lagoon nebula. The cluster M21 contains approximately 60 stars and it’s characterized by quite dense core, where the distance between neighboring stars is only one light-year.

The picture was taken under dark skies of Milos Island and it’s an integration of only 54 minutes of exposure time.

NGC6946 Fireworks Galaxy, NGC6939 Ghost Bush Cluster

NGC 6946, sometimes called Fireworks Galaxy, is a beautiful spiral galaxy located between constellations Cepheus and Cygnus. It is approximately 22.5 million light-years away from Earth and it’s a part of Virgo Supercluster of galaxies. The name didn’t get from the shape, but due to frequent explosions of supernovae.

Next to the galaxy is located NGC6939 Ghost Bush Cluster, which is a part of our own Galaxy, therefore the distance from earth is “only” 4000 light-years.

The picture is the last one from the day. I slewed to target, switched on auto guiding and went to sleep. Therefore the picture is an integration of 73 photos, each 5 minutes long, i.e. 6 hours of total time. This is probably the picture with the longest integration time from Milos.

M25 Open Cluster

Messier 25 is an open cluster in constellation Sagittarius. It’s approximately 2000 light-years from Earth and it contains 50 brighter star and probably few tens of dimmer stars. The background in illuminated by many stars, because this cluster is located in direction of the galactic center of the Milky Way.

M33 Triangulum galaxy

This is third galaxy captured on Milos. First I was not able to resist and captured Andromeda, second one was Barnard’s galaxy and third one is this one M33 galaxy in constellation Triangulum or simply Triangulum galaxy. Andromeda galaxy (biggest), Milky Way (second biggest) and Triangulum (third biggest) form local group of galaxies. M33 has diameter approximately 60 thousand light-year, which makes it half size of the Milky Way and the light from there has been traveling roughly 3 million years.

NGC7000 North America Nebula

North America nebula, also called NGC 7000, is a giant cloud of ionize hydrogen gas – HII region, located in constellation Cygnus. The shape reminds contour of the North America continent, specifically the eastern cost between Golf of Mexico and Florida. Visually, the nebula is big and it didn’t fit in my telescope/camera field of view. NGC 7000 together with Pelican nebula create a nebulae pair, which is approximately 2000 light-years from Earth.

The picture demonstrates how low light pollution on Milos Island is. The picture is an integration of only 27 pictures, exposure 3 minute each, i.e. 81 minutes in total. It’s impressive – no narrow band filters were used.

M19 Globular Cluster

Messier 19 is a globular cluster located in constellation Ophiuchus and it is approximately 29000 light-years far from Earth. This cluster is particularly interesting by its oval shape and most probably it’s the most oval globular cluster in our galaxy. The cluster, just like M9, is quite close to the galactic center.

The picture, like many others, was taken on island Milos, under dark Greek skies and it’s an integration of 58 minutes of the exposure.

M56 Globular Cluster

Messier 56 is a globular cluster located in constellation Lyra. M56 is one of less bright globular cluster, because its distance from Earth is 30’700 light-years.

This is the third (M54 and M55) globular cluster captured in single night and the picture is an integration of 63 frames, each 3 minutes long, i.e. 189 minutes total exposure time.

M55 Globular Cluster

Messier 55 is a globular cluster located in constellation Sagittarius. M55 is one of the closest globular cluster, having distance from the Solar System only 17’600 light-years, compared to M54, which is one of the furthest globular clusters (86’400 light-year). I managed to capture these two clusters during single night.

M54 Globular Cluster

Messier 54 is a globular cluster located in constellation Sagittarius. It has been assumed that the cluster’s distance is 50’000 light-years. Recently (1994) it was discovered that this cluster doesn’t belong to Milky Way galaxy, but it’s a part of Dwarf elliptic galaxy in Sagittarius and it is approximately 86’400 light-year from Earth. This means M54 is first discovered globular cluster outside of our galaxy.

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.

NGC6822 Barnard’s Galaxy

NGC6822 is a galaxy located in the constellation Sagittarius and it is 1.6 million light-years from Earth. This galaxy belongs to a local group of galaxies together with Andromeda, Triangulum Galaxy and Milky Way. This galaxy is quite famous, because Edwin Hubble discovered several variable stars in this galaxy. These variable stars can be used for determination of the distance from Earth. Barnard’s Galaxy was the first galaxy with accurately determined distance.

Barnard’s Galaxy is very dim deep space object; therefore I dedicated quite long integration time to it (180 minute) and I chose long exposure time to each frame (300 seconds). Several nebulae are visible on the picture. These are the red spots located at the left side of the galaxy. They are called Bubble Nebula and Ring Nebula and are giant HII regions, where new stars are born.

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.

M17 Omega Nebula M18 Open Cluster

Due to moderate focal length of my telescope (660 mm) I managed to capture two Messier’s object in one shot. Specifically it was Omega nebula M17 (on the right) and open cluster M18 (on the left). I already captured Omega nebula some time ago, but due to its very low declination, the picture was not that nice. I was really happy that I got the opportunity on island Milos to capture it again. The cluster M18 is approximately 4200 light-years away from Earth and it has diameter 17 light-years.

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.
