Image Description and Details :

This image shows the area of sky above the constellation of Orion. In the top right, looking like a comma is the Flaming Star Nebula. Just to the left of it is the Tadpole Nebula. If you look at the high resolution image on my website you can see the tadpole shaped structures inside it that give it its name. To the upper left is Sharpless 232 which I always think looks like a person running in a hamster wheel! To the bottom left is the large supernova remnant Simeis 147 aka the Spaghetti Nebula. This is a 16 image mosaic taken at a focal length of 530mm with a 4 inch refractor. 171 hours of light was collected through H-alph, SII and OIII filters.

Image Description and Details :

Three open star clusters are seen here in the constellation Puppis, east of the bright star Sirius. To the lower left is Messier 46 or M46, 5000 light years away. M46 has about 500 stars estimated to be about 250+ million years old. The planetary nebula NGC 2438 lies on the northeast edge of M46 (about the 11 o’clock position in the image) but is most likely not part of the cluster.
Just one degree west-northwest of M46 (to the right in the image) lies another open star cluster Messier 47 or M47. M47 is much younger in age, about 78 million years old and is 1600 light years distant. There are also about 500 stars, mostly high temperature giant blue stars, reflecting the cluster’s young age, as well as some red giants.
NGC 2423 is the open cluster just above M47 in the image and is much closer to us. It contains several red giant stars, at least one of which has an orbiting planet discovered in 2007. The distance to that system is about 2500 light years.

K2-1
A very faint and obscure planetary nebula some 3700 light years away in the constellation Auriga.
Initially catalogued as a planetary nebula, was later thought to be misclassified and considered to be either a reflection nebula (LBN 809), an H-II region, and even a galaxy (PGC 16765). However it has recently been rediscovered as a genuine planetary nebula. It has a size of 115x126 arc seconds and is predominantly OIII. The weaker Ha signal has a similar form to the OIII signal. However there's an odd small area of red nebulosity at the top left-hand corner. This is possibly some NII emission which would be captured by the 5nm bandwith of my Ha filter (the spectrum shows that NII is present).
Discovered by Czech astronomer Dr. Luboš Kohoutek in 1962 by visually examining the National Geographic Society-Palomar Observatory Sky Survey prints at the Astronomical Institute in Prague, Czech Republic
It has a mean surface brightness of 24.1 mag/arc sec.

Image Description and Details :

The dark nebula complex in the constellation of Chamaeleon emits a brown hue in the image due to its strong red and near-infrared colors. The the bright star Beta Chamaeleontis is visible just to the right of center with the dust that surrounds it preferentially reflecting blue light from its primarily blue-white color. Beta Chamaeleontis, latinized from β Chamaeleontis, is the third-brightest star in the southern constellation of Chamaeleon, approximately 298 light years away from sun. The star has five times the mass of the Sun and 2.8 times the Sun's radius.
All of the pictured stars and dust occur in our own Milky Way Galaxy with - but one notable exception: the white spot just below Beta Chamaeleontis is the galaxy IC 3104 which lies far in the distance.

This morning, February 18, I photographed this magnificent prominence on the northeast limb of the sun. These two towers of hot plasma rise more than 90,000 km above the sun's surface.
On the solar disk, not many sunspots are seen but many filaments in multiple active regions are very noticeable.
To take this picture I used a Coronado Solarmax II 90mm telescope and a ZWO 183MM camera.

Image Description and Details :

The Whirlpool Galaxy is a classic spiral galaxy. Known as M51 and NGC 5194, this galaxy may have been the first galaxy for that identified spiral structure. It is located at a distance of 30 million light years from the Sun. Measuring 60,000 light-years across, it is one of the brightest and most beautiful galaxies in the sky. The Whirlpool Galaxy can be seen with good binoculars in the constellation Canes Venatici. The M51 galaxy belongs to the Sc type spiral galaxies and is the main member of a whole group of galaxies. Astronomers suggest that the appearance of the spiral structure of the galaxy M51 is mainly due to the gravitational influence of a small satellite galaxy NGC 5195.

Also in the picture, next to M51, you can see the galaxies IC4277, IC4278 plus many small galaxies in the background.

This image was originally intended to capture an extragalactic hydrogen cloud near M51. However even 22 hours of exposure through the Ha filter gave no hint of it.

In the constellation of Rabe we see an interesting process, the merger of the galaxies NGC 4038 and 4039. This interaction will cause a rapid star eclipse. The same fate will happen in the distant future when Andromeda Galaxy and Milky Way collide. Here it is in 66 million Lj distance for us just a play in the cosmos.

Image Description and Details :

This shows the huge Seagull Nebula, and the very small (in comparison) but bright Thor’s Helmet Nebula, in narrowband.

This is an image 2 years in the making. I spent 10 full nights on imaging the Seagull Nebula wide field, as I also wanted to include Thor’s Helmet in the frame. I then added an extra 2 nights worth of data using a larger telescope on Thor’s Helmet only. This allowed me to get a nicer view on that target. All the data acquired was by myself with my own gear.

The Seagull Nebula is known as IC 2177. It is a large nebula that can be found 3,650 light-years away in Monoceros. It is a great target for both broadband and narrowband imaging, and is very close to the much smaller Thor's Helmet Nebula.

If you look closely near the Oxygen gases of the Seagull Nebula, you should be able to spot a bright star with a strange arc-shaped line of gas just above it. This is commonly known as the "Bow shockwave" in IC 2177. It is believed to come from the interaction between the interstellar dust within the nebula, high radiation winds, and gas expelling from the double star system "FN CMa”. The exact origin is still not very clear, but we might learn more about it in the years to come!

Thor’s Helmet is known as NGC 2359. It is a cloud of interstellar gas, although very faint, the colors in the gases really pop when taking long exposure shots with any camera.
This beautiful deep-sky object gets its glow from WR7, a massive Wolf-Rayet star that will soon turn into a supernova.


This is a total of 61 hours of exposure, a record for me as my longest acquisition so far was 48 hours. I captured 99% of the data from the city, Bortle 9. I captured a little bit of the data (half a night) from a Bortle 4 spot in the desert for the OIII in Thor’s Helmet.

Image Description and Details : Messier 82 is the very first galaxy I was able to observe with the naked eye with my old telescope: a C9.25 EDGE HD on a Losmandy G11 Gemini mount. This was in early January 2014, when the supernova SN 2014J was visible. It was also the first galaxy I photographed in May 2017. So it was a great pleasure to have been able to process the data of this galaxy from a much more ambitious setup.

Messier 82 (the Cigar Galaxy) is a starburst galaxy, meaning that it has an exceptional rate of star creation compared to most galaxies. It’s located approximately 12 million light-years away in the constellation of Ursa Major. About five times brighter than the Milky Way, the intense star formation activity was triggered by an interaction with the neighboring galaxy M81.

Image Description and Details :

M106 galaxy dominates on this image. Also known as NGC 4258, M106 is about 80,000 light-years across and 23.5 million light-years away, the largest member of the Canes II galaxy group. For a far far away galaxy, the distance to M106 is well-known in part because it can be directly measured by tracking this galaxy's remarkable maser, or microwave laser emission. Very rare but naturally occurring, the maser emission is produced by water molecules in molecular clouds orbiting its active galactic nucleus.

The following galaxies can also be seen in the image - NGC4248 (bright at the left-bottom of the center), UGC7356 (above M106) and a pair of galaxies NGC4231 & NGC4232 (in the lower left corner of the full-size image). Beneath NGC4248 is also a cluster of distant little fuzzy galaxies.

What interesting is that this image reveals one of the two faint hydrogen jets inside M106 (2 o'clock from galaxy center).
