Cepheus Elephant trunk nebula Explore scientific coma corrector IC1396 iOptron CEM25P Milos Nebula Newton 150/600 ZWO ASI071MC Pro

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.

Crescent nebula Cygnus DSO Explore scientific coma corrector H II nebula iOptron CEM25P Milky Way Milos Nebula Newton 150/600 NGC6888 ZWO ASI071MC Pro

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.

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.

B347 Barnard347 Butterfly nebula DSO Explore scientific coma corrector IC1318 iOptron CEM25P Milos Nebula Newton 150/600 ZWO ASI071MC Pro

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.

Messier M4 is a globular cluster located in constellation Scorpius. It has approximately 100 000 stars and it’s roughly 7200 light-years away from us, which makes it one of the closest globular clusters to the Solar system. Hubble Space Telescope discovered many white dwarf stars, which are the oldest known stars in our galaxy, having an age of 13 billion years.

The picture was taken during my travels to Greek island Milos and it’s only integration of 24 of two minutes exposures. This means only 48 minutes in total.

After capturing many clusters I wanted to switch to more interesting objects, which would test the quality of the skies on Milos, therefore I slewed my portable newton telescope to probably the most famous galaxy – Andromeda. During the post-processing I was astonished how many details were revealed after such short integration time. I would not be able to capture such picture from home, even if I would use any light pollution filters and much longer integration time.

Brief description of the galaxy: Andromeda is our galactic neighbor and it is approximately 2.5 million light-year from Earth, but it is approaching (110 km/s). There are estimates that our Milky Way and Andromeda will collide, but we still have some time, because it should occur in 4.5 billion years. Andromeda has diameter 220 thousand light-years, which makes it twice bigger than our own galaxy Milky Way. Two clouds surrounding the main galaxy are dwarf galaxies M32 and M110.

Messier 24, also called Small Sagittarius Star Cluster, is a giant cloud of stars and open star clusters. In fact, M24 is not gravitational bonded object, but it is only spiral arm of Milky Way galaxy. The light coming from the cloud is partially blocked by two prominent dark nebulae. The cloud is literally surrounded by Messier objects. In north-east direction can be located Omega Nebula M17 and open cluster M18, just 3° direction north open cluster M25 can be seen, 5° direction west open cluster M23, 6° south-west nebulae M20 Trifid and M8 Lagoon nebula.

Cluster DSO Explore scientific coma corrector iOptron CEM25P M7 Messier7 Milos Open cluster ZWO ASI071MC Pro

Similar to M6, there is another bright open cluster in constellation Scorpius called Ptolemy Cluster or Messier 7. The cluster was discovered very long time ago (130 BC) by Greek astronomer Klaudios Ptolemaios. It belongs to one of the brightest and the biggest star clusters, which are visible by naked eye, but not from Central and Northern Europe. The open cluster M7 consists of several hundreds of blue stars and it’s approximately 1000 light-year away from Solar System. The background illuminates our home galaxy Milky Way.

To capture this cluster was quite tricky. First two attempts were interrupted by windy and cloudy weather. During the third one I managed to expose 17x 120s and 8x 180s, i.e. 58 minutest in total.

This spectacular globular cluster is called Messier 22 or Great Sagittarius Cluster. It’s located, surprisingly, in constellation Sagittarius, close to Galactic Bulge, therefore the background is illuminated by many stars. Oh, and it’s so many of them. If you realize that each bright dot is a star and most probably not just a star, but whole solar system, it makes you think how big the universe is. The distance from Earth only 10’000 light-years, makes this cluster the closest one to us.

Due to its low declination, it’s quite difficult to photograph this cluster from Central Europe. Therefore I took the opportunity and captured M22 on Milos Island. The picture is an integration of only 94 minutes.

M6 is an open cluster located in constellation Scorpius. Visually it’s located not far from horizon, at least from Central Europe; therefore it’s hard to capture this deep space object. The observing/capturing conditions change significantly if you travel to Southern Europe. From there the cluster is visible by naked eye. The stars from similar shape to butterfly, therefore it got its name. On the bottom side of the cluster is nicely visible red giant (orange star) called BM Scorpii. The background illuminates the Milky Way.

The picture was taken during chasing darkness on Greek island Milos and in total was taken 30 pictures having exposure 180 seconds, i.e. total 90 minutes of integration.

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.
