Description

Hello friends!

This is my annual iteration of M33, one of our local group of galaxies and one marked by a plethora of nebula.  Its beauty (to me) is in its tilt, its red punctate nebula, and bluish hue.  This data was captured in the middle of October, and while that was very fun,  my work life changed gears and I didn't have much time to devote to my AP.   More's the pity, I won't be doing that again.. .

The target -  M33 - paraphrased from Sky Safari:

"Messier 33 (NGC 598) is commonly known as the Triangulum Galaxy. Barely visible to the naked eye, this nearby spiral is the third-largest galaxy in the Local Group, after the nearby Andromeda Galaxy (M 31) and our own Milky Way.  The Triangulum Galaxy was discovered by Hodierna before 1654, who may have grouped it together with the open cluster NGC 752. The galaxy was independently rediscovered by Charles Messier in 1764, who catalogued it as M 33. The galaxy was not noted by any known pre-telescopic observer, which is not surprising: given its indistinctness, it is not likely to be noticed unless one already knows of its existence."

I also looked up NGC604, as its a rather bright blob top left in M33.

Wiki says (to paraphrase) -> NGC 604 is one of the largest HII regions in the local group of galaxies.  Its roughly 1,520 light years across and over 40 times the size of the visible portion of M42. Its gas is ionized by a cluster of massive stars at its center=10.5px with 200 stars of spectral type O and WR.  

Thanks for looking,
Ian

Title: Rig image

Description: This is my rig for that nice evening. Our farm is near the big city, so there is some light pollution to the north, but its not limiting to imaging, unless you are low in the north. 120 mm refractor on my AP 900.
