Well deserved reprocess of my favorite DSO Rho Ophiuchi.
Taken in Chille with Canon 6D, Samyang 135mm @f2, 50x60s, ISO800, mount Skywatcher Star Adventurer mini.
Image stacked and partially processed in Pixinsight and finished in Photoshop.

M77. KG Observatory, Julian, CA.
Object 2 of 2 from my October/November dark cycle.
Here I used 5-minute L subs to help expose more of the very bright core. The spirals emminating from the core looked to be a bit stronger in the R channel. 45 minutes of screened Ha helped highlight that.
All processing uses 2x Drizzle to help increase resolution for a narrow shot. (-:
"Initially identified as a nebula by the French astronomer Pierre Méchain in 1780, M77 is one of the largest galaxies in the Messier catalog. It is located in the constellation Cetus at a distance of 45 million light-years from Earth.
M77 is a prime example of a Seyfert galaxy, or a galaxy with an intensely active center that is obscured by gas and dust in visible light.
Only one supernova has been detected in Messier 77. The supernova, named SN 2018ivc, was discovered on 24 November 2018 by the DLT40 Survey."

I always look forward to your images, and you never disappoint!
That's a great portrait of M77! I love the fact that you bring out so much of the outer faint parts of M77. If you compare it with a
NASA/ESA image, it only shows the bright inner spiral of M77. And those that show as much of the outer parts of the galaxy as your image does overexpose the bright inner bulge more than you do. In short, this is a superb image!

Thank you Ann for your great feedback! I do find many of the HST images focus on galaxy cores. I suspect that may be due to their available FOV at the time and/or limited integration time. It's always fun to see what else might be there. (-:

This is a really great catch! Beautiful! And the comet looks great, and the meteor most certainly does (and the globular isn't too shabby, either)!
