Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

M101 - The Pinwheel Galaxy: Things don't always work out!

I first shot the Pinwheel Galaxy last year using my One-Shot-Color Camera. I wanted to try it again and see what I could get using a mono camera and L,R,G,B & Ha filters with a longer set of exposures.

So I recently imaged this target over the span of 5 nights, starting on May13. I collected the normal LRGB filter data and I also collected some narrowband images through my Hydrogen-Alpha Filter. The equipment is pretty automated now so I could get things running and then try to sleep on the sofa - still keeping a general eye on things during the night…..

C49: The Rosette Nebula in SHO

Astrobin Top Pick!

Also known as the "Skull Nebula" and Caldwell 49, the Rosette Nebula is a large HII region of bright gas and filaments of dark dust, located in the constellation of Monoceros. The open cluster NGC 2244 (discovered by John Flamsteed in 1690) is associated with this region - the stars of which were formed within this molecular cloud. Located 5000 light years away, and measuring 65 light years in diameter,

NGC 4631 - The Whale and the Hockey Stick (NGC 4656) - A second attempt, this time in LRGB-Ha…

The Whale and the Hockeystick are two galaxies are found in the constellation Canes Venatici, about 30 Million Light years away. This is my second time shooting this target and the first where I used a mono camera and captured LRGB along with some Ha subs folded in for good measure. As it worked out, I captured a possible supernova that was recently discovered as well.

SH2-155 - The Cave Nebula

SH2-155 - The Cave Nebula - also known as Caldwell 9, is a diffuse nebula found in the constellation Cepheus. It is actually a part of a much larger complex of nebulae n the region which includes the emission, reflection, and dark nebulae. The designation indicates that this part of the Sharpless Catalog of emission nebulae which are located north of the declination -27 degrees. Sh2-155 is located 2400 light-years away and is an ionized HII region with evidence of star formation activity.

IC 405 - The Flaming Star Nebula

IC 405 - The Flaming Star Nebula, also known as Caldwell 31, is a nebula in the constellation Auriga surrounding the bright blue irregular variable star AE Aurigae. This nebula is located about 1500 light-years away and is about 5 light-years across. The red portions are from emission nebulae, while the bluer portions are reflection nebulae, reflecting the light of AE Aurigae.

IC 1795 - The Fish Head Nebula in SHO

IC 1795 - The Fish Head Nebula in SHO

IC 1795, also know as the Fish Head Nebula, is an area of new star formation with glowing gas and dust, in the constellation of Cassiopeia. It is actually a portion of the larger Heart Nebula complex (IC 1805) that is located about 6000 light-years from earth. Since my scope cannot fit the entire Heart nebula into its field of view, I opted to frame just the fish head portion of the nebula. This was to be shot with my Mono camera and narrowband filters so that I could get the Hubble Palette colors that I am quite fond of.

Messier 1 - The Crab Nebula with an SHO/RGB Blend

Messier 1 - The Crab Nebula. Also, known as NGC 1952 and Taurus A. Now, THIS is a pretty cool object! This is the remains of a star that went Supernova and was seen as a bright daytime star back in 1054 by Chinese Astronomers. It was discovered by English astronomer John Bevis in 1731. It was also independently discovered by Charles Messier in 1758 when he was trying to find the return of Halley's Comet.

IC 5070 - The Pelican Nebula in SHO

IC 5070 - The Pelican Nebula. This rich region of gas and dust is located 1800 light-years away in the constellation of Cygnus, the Swan. It is separated from the North American Nebula by a dark region of dust. The Pelican Nebula is very active in star formation and the growing collection of hot new stars being created there are slowly transforming cold gasses to hot gases that are ionized.

NGC 7293 - The Helix Nebula

NGC 7293, better known as the Helix Nebula, Caldwell 63 and in pop culture as "The Eye of God" or the "Eye of Sauron" - is a planetary nebula located in 655 light years away in the Constellation Aquarius. Planetary Nebulae are formed when an intermediate to low-mass star sheds its outer layers as it reaches the end of its life. The Helix Nebula is one of the closest planetary nebulas to the Earth, is estimated to be about 2.5 light years in diameter.

NGC 7635 - The Bubble Nebula in SHO

NGC7635 - The Bubble Nebula - A narrowband image in the Hubble Palette. Also known as Sharpless 162 and Caldwell 11. The Bubble Nebula can be found in the constellation Cassiopeia, not far from the Open Cluster Messier 52. This area is a rich HII region and the bubble itself was created by stellar winds from a massive hot blue Wolf-Rayet star, AO 20575, that shed its material about 300,000 years ago to form the bubble. This star is 44 times larger than our sun. The Bubble itself is found in a massive molecular cloud that contains the expansion of the bubble and is excited by the same star, causing it to glow as well.
