Astronomy shots

Rather than clutter up the Where You Are Photos topic, I figured it was probably best to start a seperate thread. Please consider it open for all to post their night sky photos/images regardless of equipment used.

To kick things off…

The Elephant’s Trunk, part of the nebula IC1396 in the constellation Cephus. This target needs a lot more exposure time, but considering I was learning new software and equipment, I’ll take it.

Posted previously, M27 - The Dumbbell Nebula found in the constellation Vulpecula…

This is the Milkyway taken with my iPhone 11 Pro using the night mode… You can see the constellations of Sagittarius and Scorpius, so this is looking directly towards the galaxy’s core.

I took this tonight.

Not bad for a phone (Samsung Galaxy S23)

30s at ISO1600.

I also took one with the ultra wide camera but for some reason it is purple. And since I used a footstool as the mount I could only shoot straight up.

That is very impressive for a phone shot.

I have been trying out a piece of image processing software called PixInsight. It’s not cheap, but it can do some clever things to get the best out of your images. Combined with some payware plugin’s it is quite remarkable how it can eliminate background noise and sharpen detail. I might have to get my wallet out once the trial period is over.

Before:

The same image processed with PixInsight

M16 ‘The Eagle Nebula’ taken with my old monochrome camera back in 2017, reprocessed with PixInsight.

the three shots from your first post are like:

" first is juicy steak, second here are bbq ribs … and this third one is hot dog, you can see onions and mustard, so then with sausage right in the core "

:wink:

disclaimer: joke above doesnt work for hot dog lovers

great shots btw :slight_smile:

Another from 2017, reprocessed with PixInsight… M17, the Swan Nebula.

Last shot until I have some new objects to show you. This is the M27 image, reprocessed with PixInsight.

I dug up another image from a few years ago and gave it the PixInsight treatment…

M42: The Orion Nebula…

M42 is surprisingly tough to process if you don’t want to blow out the core.

This is a phone shot take using my shiny new iPhone 15 Pro… quite a difference from the iPhone 11 Pro shot.

I played with the image a bit in PixInsight.

Just in case anyone is interested in what an imaging session looks like…

This is actually a Remote Desktop from a mini-PC strapped to the tripod leg of my imaging rig. The center panel shows the latest exposure while the graph at the bottom lets you monitor the auto-guiding performance (it’s giving me fits this evening). The software is called N.I.N.A (Nighttime Imaging ‘N” Astronomy). I am still getting to grips with it and I have a lot of learning to do. The program can automate pretty much every aspect of an imaging session with the use of ‘Sequences’, where you drag and drop actions into a sequential list. I guess a form of visual programming. What is amazing to me is that N.I.N.A is free, or at least donationware. I will have to send the author some funds I think.

It looks like I might get a half decent image out of this evening’s session.

That is some cool stuff!

I’m not completely happy with the processing…but I think it came out quite nicely…

NGC7331, a spiral galaxy found in the constellation Pegasus. Estimated to be 49 Million Lightyears distant and 300,000 light years across.

That’s awesome!

Awesome! Curious about how long exposure would be needed for this photo?

It is a stack of 72 x 3 minute images (known as subs in the Astro-imaging world). So 216 minutes worth of exposure. By stacking (or averaging) the sub-exposures, you average out most of the noise, leaving you with a nice clean image.

This is probably the best galaxy image I have taken to date.

Just incredible…!

Thanks for the details. That is great work indeed.

Knowing that there is some serious work involved in creating these incredible images makes it even more respectable!

And not to mention the need for clear skies

So how does this work? Are you planning the photo session ahead and then just execute the plan? How much hands on is the process during the night. With 3 min exposures I guess your telescope has some kind of automatic tracking.

@PaulRix Those shots are pretty incredible. What kind of equipment are you using?
