NGC5430 Bumble Bee Galaxy (my name for it)

 NGC 5430 is an Spiral Galaxy located in the constellation of Ursa Major (Big Bear, same as the Big Dipper Constellation). NGC 5430's distance from Earth is 129,989,624.33 light years. It is TINY to try to photograph and is only 12 magnitude in brightness. Immensely dimmer than stars seen with the unaided eye. Could we actually call this the Bumble Bee Galaxy!


The Owl Nebula

 The Owl (face) Nebula is a planetary nebula approximately 2,030 light years away in the constellation Ursa Major - the same constellation that holds the Big Dipper. Estimated to be about 8,000 years old, it is approximately circular in cross-section with a faint internal structure. It was formed from the outflow of material from the stellar wind of the central star. What that means is this little guy is very pretty to look at. To take the photo I had to take 100 45 second light frames while star guiding with guiding software. If I didn't use a separate guide scope the imperfections as tiny as they are, would make the picture look like I took it from a rock invested road.

NGC 4565 (IC3543) Edge On Needle Galaxy

NGC 4565 is known as the Needle Galaxy or IC 3543.  It is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. To be seen without optical add magnitude 6 would be necessary. It is known as the Needle Galaxy for its narrow profile. NGC 4565 has at least two satellite galaxies, one of which is interacting with it. Can both satellite galaxies, they are in my picture. It has a population of roughly 240 globular clusters, more than the Milky Way.

Messier 101

Messier 101 (M101) This bad boy face-on galaxy is 170 light years wide and its distance is a mere 21 million light years away. This galaxy is much like the renowned Andromedia Galaxy. You may remember an earlier photo of M101 I posted about a year ago which included an exploding supernova. That supernova is no longer visible as the star is dying and a goner.
My picture this year is at FL1470 as last years was FL 517. This year I took a stack of 109 frames each 30 seconds of exposure. With 30 seconds I include guiding in the process to ensure the scope mount does not drift too far off target. The final stack had the stars removed and several Generalized Hyperbolic Histogram stretches applied. Finally, the stars were standard histogram stretched and accurately placed back on the GHS stretched stack. The results are below:
