The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is cataloged as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.

The Eastern Veil Nebula NGC 6992

The Veil nebula has been my deep sky subject for the past month, and I'm finally done with the eastern portion. The desert heat and humidity we've had recently did not help at all, but us desert rats find ways to overcome this every summer. 

Next up is the western portion of the Veil nebula, which contains NGC 6960 the Witches Broom Nebula. I'm hoping to get the western side done before the end of the month.

Comet 41P/Tuttle-Giacobini-Kresak 4-1-17

This was my first attempt at imaging a comet, and after tons of research online I was actually able to pull off some interesting images, and even a video of its movement. Comet 41P/Tuttle-Giacobini-Kresak was not showing any signs of a tail, at least for now. The comets closest approach to the Sun is on April 12 2017, and it might start showing signs of a tail around then. Unfortunately, this comet is not really a naked eye object, and was even hard to spot in binoculars under our light polluted valley. This is why it's important to always turn off unnecessary lights at night, and if at all possible use lighting that does not pollute our night skies.

There are various ways to post process a set of comet images, one way stacks the comet and leaves the stars to trail. The other way is to stack the stars and the comet, which leaves you with a nice comet and a fairly clean star field in the background.

Cigar Galaxy (M82), Bode's Galaxy (M81)

Bode's galaxy (M81) is a large bright spiral galaxy located approximately 11.8 million light-years from Earth in the constellation of Ursa Major. The Cigar Galaxy (M82) can be found right next to M81 and resembles a cigar of sorts. This pair of galaxies look amazing next to each other, and the differences between them is striking. NGC3077 completes this trio of galaxies, but is more of a faint blob compared to its neighbors. I took these over a 3 week period in by backyard in Cathedral City California.

Here are the 2 images stitched together, creating a wider field of view. I also was able to add some H-Alpha data to M81 which gives it a bit more color

This next image was taken with a Orion ST80 which has awider field of view and shows all 3 galaxies

Moon Craters taken 3-8-17

I snapped an image of Clavius (crater) and Longomontanus (crater) the other night. The seeing was amazing, and the images show all kinds of detail.

Jupiter rotation video 3-8-17

The other night I was out in the backyard imaging Jupiter and decided to make a rotation video of the planet. I ended up with 2 separate videos because the seeing changed and I had to reduce my magnification a bit. The end results turned out pretty good though!

These were made up of individual images taken every so often between 11pm and about 3am, so around a 4 hour period of rotation.

Jupiter 2-1-17

Finally, Jupiter is back in the night sky! Oh, how I have missed this beautiful gas giant of a planet. As much as I enjoy imaging deep sky objects, my first love will always be planetary imaging. There is just something about imaging our local neighbors that puts me in a wonderful mood. Watching Jupiter rotate throughout the night is a sight to behold, and for such a large planet it does so about every 10 hours as opposed to our 24 hour Earth rotation. This means I can watch the great red spot on Jupiter slide across the surface in a matter of hours, and I can even see the movement of its 4 brighter moons. The black dot you see in the image is a shadow transit of Europa, one of Jupiter's larger moons.

P.S. This is my best image of Jupiter...so far
