This is M101, the Pinwheel Galaxy.
It is located in the Usa Major constellation about 21 million light years from Earth. It has a diameter of about 170000 light years, almost twice the size of our Milky Way galaxy. Again, this is a RGB (red/green/blue) true color image, although I did blend in some Ha (Hydrogen Alpha) narrowband data to help the red channel. C9.25 SCT, .63 corrector reducer, focal length 1405mm @f6.3 ASI 1600MM Pro ZWO R/G/B/Ha and EFW 60mm guide scope with ASI 120MM-S camera EQ6-R PRO Moonlite focuser Pixinsight/PHD2/Photoshop/Sharpcap All bin 2x2 Red 68subs @ 150s Green 69subs @ 150s Blue 70subs @ 150s Lum 46subs @ 60s Ha 70subs @ 240s Total exposure integration 14.05 hours Uncropped image:  Attached File |

Nice picture. That is a ton of emission nebulae compared to andromeda. must be a lot of young/new stars over there. That one is always hard to find due to low surface brightness, only ever saw the very center of it once to check it off the messier marathon

Magnificent. It's amazing what can be achieved by amateurs with small telescopes, digital cameras, and image stacking. Astronomy has advanced tremendously in the last decade or so.

Astronomy has advanced tremendously in the last decade or so. I'm 68 years old and I have had a telescope since I was in high school. But I never even thought about astrophotography until the digital camera age. Doing astrophotography with film was just way out of my wheelhouse, even though I had a darkroom and developed my own camera films... |

Thanks for showing these OP and very well done!
We sit here on our little planet, hurtling through space on a one way journey. Where we are now no one has ever been. Where we are now no one will ever be again. Dust in the wind and all, but you have shown us the vastness, the unimaginable size, that's fantastic. Then there is time with all of its vastness. Wow! |

It has a diameter of about 170000 light years, almost twice the size of our Milky Way galaxy. 1 light year is 5.879-trillion miles. So this galaxy is 21-million * 5.879-trillion = 123.5-quintillion miles away, if I'm doing the math correctly. And this galaxy is considered to be "just around the corner from us". It isn't in the Local Group but it is part of the Virgo Supercluster of galaxies, which I believe encompasses several tens of thousands of galaxies. The Virgo Supecluster is one of about 10-million known superclusters in the observable universe. M101 is estimated to contain about 1-trillion stars. OP that is some damn fine astrophotography.

Pretty crazy, just looking at those nebulae in the picture, there is a non-zero chance that a civilization over there has named them after a mythical figure (like orion the hunter), or assigned them a number in a catalogue, or had a conversation like this about the milky way |

I have to ask...how much has starlink tossing up satellites in the sky like candy hurt this hobby?
I actually have an astromount, pretty sure it is an Orion Sirius Pro AZ/EQ-G. I think they sell a newer type controller for it as I have had it for 8 years but used it only a handful of times..  I don't have any telescopes as I wanted to do astrophotography from the start. It looked to be very involved process of picking the right equipment of what will work for the gear you want to use. I do have several DSLR's and some exotic lenes that I wanted to practice with first, my health and divorce put a kabosh on it and never really got back into it. I think the problem is with astro I needed to modify my camera for the light I wanted to capture, at that point a 600mm F4 lens can show bright spots and ruin the photo as it wasn't designed to handle any type of IR light. The second part of doing this is it takes hours in the middle of the night to stack all the photos, usually multiple nights for that matter. Then I am a good 4 hours to any type of "zone" that I might get something good (forgot what the levels of light pollution they used). The other stuff I never really got around to is all the software for tracking, the tracking camera, and then the software for stacking it all together. Meh...might give it another whirl, what could go wrong....
