Alright folks, about to share some of my dodgy pics that got me all excited yesterday, about finding my 3rd galaxy ...
Some folks asked me so just to clarify, not a new discovery (!) but just me being able to find/photograph a known galaxy (sorry bout wording!)

So my exciting news, caught my 3rd galaxy this week!
Caldwell 83 now joins Centaurus A and Sombrero in my collection composite!
Images in left column are me, images in right are Hubble & Martin Pugh (Caldwell 83).
A short, photo-thread of some pics from this week...

Now the image I took is nothing special, but like all my images, a number of factors:
1. Learning
2. Close to city lights
3. Moon!
4. Only 20 x ~ 0.5s frames, integration time ~ 10 seconds
5. No flats/darks etc.
6. Adjusted on phone apps (Insta + PS (free))
But it's there!

Here's my (dodgy) image next to the excellent APOD captured by Martin Pugh
Caldwell 83 is about the size of the Milky Way, and located 13 million light years away in the Centaurus constellation. It's a large spiral galaxy (another first for me!) being seen almost edge on.

In addition to Caldwell 83, I got my best shot so far of Centaurus A. (NGC 5128).
This lenticular galaxy is also ~ 13 million light years away and in Centaurus (they're part of the same cluster).
Look at those dark dust lanes!

Here's the Hubble image of Centaurus A. on the left, vs. my most recent image (taken earlier this week - surprised me as the Moon was out and rising!)
Note the little pink colour in centre of dust bands :-D
(I also have no idea how my images are orientated)

And since I was having a look around the Centaur as he sat near the zenith, couldn't go past the Omega Centauri globular cluster.
This city of about a million stars is thought to be an ancient galaxy that got cannibalised by our own.
This is my clearest pic of Omega Cent.

And lastly, I was processing some DSLR images I took last week when I found a shooting star! Just above the palm tree and diving into the light pollution, as the Milky Way pours into the horizon.
If you look careful, you can see the Large Magellanic Cloud to its left.

Hope you enjoyed this short thread as much as I did finding these treasures in the photos.
Tune in same time tomorrow as I take a look at the spectrum of a couple of bright stars from the rooftop :)
