M98 Galaxy

Messier 98 is a spiral galaxy located in constellation Coma Berenices. This galaxy is easy to find, because it is located only 6° to the east from the bright star Danebola. M98 is approximately 44 million light years away and it has a blue shift. This means that it is approaching us at about 140 km/s. This means we have still some time till the collision occurs.

M49 Galaxy

Messier 49 is an elliptical galaxy belonging to the Virgo Cluster of galaxies. Magnitude 8.4 makes this galaxy the brightest in whole Virgo Cluster. Due to its brightness, it’s possible to observe it just by using binoculars. Distance of M49 from Solar system is 52 million light-years.

The picture is a stack of 40 photos with exposure time 5 minutes each. This means more than 3 hours of exposure time.

M95 Galaxy

Messier 95 is a spiral galaxy, which is located in constellation Leo. It is 38 million light-years away from Solar system and it belongs to a group of galaxies with M96 and M105. M95 belongs between the galaxies intensively studied by Hubble Space Telescope, in order to determine Hubble’s constant. Collected results were adjusted with help of satellite Hipparcos and the distance of this galaxy was estimated. The galaxy is drifting away from us by speed 766 km/s.

M96 M105 NGC3384 NGC3389 Galaxies

Four bright galaxies in one shot! M96 on the lower left, which I already captured last year. At that time I didn’t know, that there are other galaxies, which can fit into the field of view of my camera. These are: M105 circular, lowest in the galactic triangle, MGC3384 – right in the galactic triangle and NGC3389 – left one in the galactic triangle. These galaxies are located in the constellation Lion and they are visible during the spring. Therefore I call the spring the season of galaxies. The weather last year was much better and I captured many of them. For instance here or here or here or here or here.

M50 Open cluster

M50 is an open cluster located in constellation Monoceros, visually not far from the brightest star Sirius. It was catalogued by Charles Messier in 1772 and it’s approximately 3000 light-years away from Earth. The latest research was conducted in 2012 and confirmed that the cluster contains 508 stars – you can try to count them.

Moon – Waxing Crescent

After long period of bad weather, I had the opportunity to take the telescope out and enjoy the clear skies. In the early evening, waxing crescent was setting down, so I took the opportunity and pointed my newton on the Moon. The illumination was only 34%, which means that as soon it gets dark, the Moon is not far from horizon and you have to capture it through thick layer of turbulent atmosphere. The picture is a stack of 700 frames.

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).

Neptune

Since Pluto is no longer a planet, the privilege to be the last planet of the Solar System belongs to Neptune. Neptune is after Jupiter and Saturn the third most-massive planet. It has approximately 17 times more mass than Earth. One year on Neptune takes 164.8 years, because the distance between Sun and Neptune is 30 times longer than between Earth and Sun. The planet got its name from Roman mythology, specifically after the god of the sea – the mighty Neptune.

Neptune cannot be spotted by a naked eye, therefore one needs telescope. Even if you have one and you manage to find it, you will not see any details on Neptune’s surface. You will see just boring small spot.

The picture was taken by my biggest telescope Celestron C14. The focal length 4000 mm was increased by 1.6 Barlow lens to 6400 mm. The seeing was, as usual, very bad, therefore there are no details visible and the picture looks not perfectly focused and unsharp. I just wanted to try to capture it and here is the outcome:

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.
