Likely just a coincidence that they created a recognizable shape, given that they tend to constantly move in and out of flux.

I see pareidolia.

my first attempt at M31 (Andromeda Galaxy) this year.
As our neighbor galaxy is so freakin huge in the sky, it more than fills the sensor of my camera when shooting through my telescope.
The plan was to capture both halbes and combine them later in post.
But sudden dew in the middle of the session destroyed that plan.
Still, half a galaxy is better than none.

 

[Owain Taggart]

Nice! That's a great attempt. It's quite amazing what we can capture isn't it? It's the kind of shot that is awe-inspiring, and I actually feel the noise adds to the effect.

Do I see a Kelvan ship heading this way...?

Do I see a Kelvan ship heading this way...?

I don’t know. Have we ever seen one?

 

[publiusr]

I saw ISON

No actually I haven’t...

Nice image here of a galactic nucleus

I had to work a bit harder in post processing into this one to make the data come out of hiding. I actually bothered to make it look as nice as possible unlike that botched Andromeda pic earlier.
NGC 281, Pacman Nebula
Without the Ha emissions which my camera can not pick up the Pacman is hard to see (also, it's "upside down" but I liked the framing best this way.)
the active starforming region t's located in the Cassiopia constellation.
It has been discovered in 1881 already by E. E. Barnard (pretty sure it was not named Pacman back then).
I wa a bit surprised it's not listed as a Messior object, but I guess emission spectrum makes it pretty difficult to discover visually.

Some nice comet photos?

Dean! Wah!

I hope eventually.
I have yet to get a good opportunity to image it.
Best one so far I had to do with a shaky cam standing under a street lamp before it was fully visible to the naked eye.
Photo was less than stellar, so I won’t bother posting it.
But give me a few days.

curious what others can come up with, though.

Comet NEOWISE last night between the stars Al Kaprah and Talitha.

 

[Owain Taggart]

I was wondering if someone would post a pic of the comet. I saw it naked eye a few nights ago. At first, I was doubting what I was seeing, but as it got darker (and we have very dark skies out where I live), it just got better and better. With averted vision, you could see a longer tail.

 

[Gordie]

NEOWISE again.

 

[Owain Taggart]

Keep them coming! It looks better and better. How are the skies where you are? Fairly dark?

 

[Timelord79 (he/him)]

Middle of the road. Ok-ish for a small town.

i will drop my own NEOWISE image soon.
I am shooting it right now.
Though with telescope.
I realized I have line of sight from my balcony today and jumped at the opportunity.

so, look forward to a close up of the green glowing nucleus and the densest part of the tail.

[Gordie]

I got quite a few nice ones last night. I won't clutter up the thread though.

From my backyard.

 

[Timelord79 (he/him)]

How long was the exposure?

 

[Gordie]

How long was the exposure?

I think 5 seconds? But I enhanced it with the photo editor.

This one was here was 5. Photobombed by satellite.

 

[Timelord79 (he/him)]

I finished a new Moon image. Tried really hard to pull out the surface colors while maintaining a natural overall tone and not destroying details. Really hard to balance.

 

[Owain Taggart]

That's a really nice crisp image of the moon!
