Faint southern spiral galaxy IC5332

I have been in equipment fiddle world for a while but its sorted now.

So this is the first image for a while. I actually have several that are waiting to be processed. Setting up a new computer, getting all the bits and pieces and the multitudes of licenses and registrations all entered again has taken a while.

Spiral Galaxy IC5332. I first saw this one when Jase did an image of it about a year ago. Its been on my wishlist since. It appears to be a fully side-on spiral galaxy with a tight spiral structure much like the Northern M101.

Its quite faint. This is 12 hours total with some Ha (didn't really add much).

AP1600GTO mount, AP RHA scope and Trius 694 camera.

Exquisite. Superbly beautiful. Wonderful detail. Another extra-low surface brightness galaxy well captured.

Very nice detail in there for such a small and dim galaxy, very nicely captured

Yaaay finally another image from Greg

Glad you sound like you have sorted some of your issues mate

Not a bad result, it is a faint galaxy ...actually, I started on this last new moon too so given we use the same camera and rather similar scopes, it should be an interesting comparison...oooh pressure!! taking on an AP RHA

That seems only to be a small file you have posted...?

A very cool target, Greg, and it has come up nicely. Great to see you producing images again!

Cheers,
Rick.

An interesting looking galaxy Greg. I like the colour and the detail in the galaxy is good. That back ground galaxy that is interacting really adds to the image.

I would have liked to see a larger image so that one can take in all the detail.

Hi Greg,

Great to hear that you have sorted out all technicalities.

A very nice photograph of a relatively neglected by astroimagers target

I think at around 2 o'clock in the background just above the main galaxy, there are two spiral galaxies colliding with their discs oriented at 90 degrees to each other.

amazing shot Greg, the hi res version is fantastic, it shows up many faint surrounding galaxies

Sorry for the slow response. My Wins 10 browser suddenly would not connect to iceinspace and I thought the site was down when it wasn't.

Thanks for the nice compliment!

I was happy with the detail and the sharpness. It took a fiar bit of work to tweak the squareness of the camera and to work out which corner of the camera corresponded to a particular corner of the image.

I started to do the Atom nebula and then you posted your cracker of an image so that is shelved for now! So its only fair!

Thanks Rick. I have several that are backlogged for processing. I had to reload all my software, regain licences etc. It takes a while to recover from a computer crash.

Thanks Paul. It could do with more exposure but am happy with the result so far. I may add to it next new moon. I'd like to smooth down more like your images which are usually very smooth. F3.8 and a sensitive camera still requires plenty of exposure time to get clean.

Greg.

Thanks Slawomir. Those background galaxies are interesting. Its amazing what shows up when you stack all that data.

Cheers Aidan. I am often surprised at how many background galaxies these deep sky images show up.

Ooh, not even a little tweak? Just a little little bit more?

Thanks Russell. I was happy with the detail after numerous attempts to process it. It wasn't straight forward. I think the Trius 694 suits the Honders quite well. Its particularly good for narrowband.

Very sharp detail Greg, but the overall look seems a bit too magenta for me.

Thanks Geoff. Someone else commented the same. I have lowered the magenta and reposted to the same link. It is quite a blue galaxy and the only image apart from Jases is David Malins photographic image and its quite blue.

The Ha I took did nothing really. It should have showed a bit more. Perhaps longer Ha may bring out the little Ha knots better.

Greg.

It's indeed a difficult target Greg. Tried it myself many years ago. You have definitely done it justice.

Cheers

Thanks. What does Roland call them? Deer eyes in headlights?
Diffraction spikes are ok but occasionally I see an image with massive ones and they can really detract from the image in that case.

Thanks Steve. I'm also happy this was from my home observatory not my dark site.

Greg.
