Very nice capture!

As for suggestions for improvement, these kinds of shots are all about detail and vibrance, so I would start by cropping away some of the negative space in order to make the galaxy fill more of the frame and thus appear larger. The upper-left is quite soft, so I'd definitely exclude that.

Also, perhaps a bit of NR followed by some sharpening might increase the apparent level of detail, though it's hard to say at this resolution.

Thanks Adam. I appreciate your comments.

G'day Frank,

This is a good effort mate and I think you have an image that has more potential than you're showing here.

I'm not sure how you feel but the Milky Way to me looks more impressive when there's something in the foreground like mountains, trees etc. Each to their own of course and the time of night and time of year will determine what options you have to set the Milky Way against, but for future images I'd recommend trying to include something to contrast against the Milky Way. For this image I agree with Adam to crop to make the Milky Way a more prominent part of the image.

I'd also suggest looking at your post processing of Milky Way images. Some of what works with these images is counterintuitive to what you would normally do, for example more contrast or pushing up the whites and pushing down the blacks more than normal. As the stars are a single point of light it doesn't really matter if the PP software indicates the stars are over exposed. At the same time you can try pushing the colour channels or the saturation/vibrance. If your software allows it there's more control doing the individual colour channels as you can raise the luminance of individual colours without adjusting others. In this image I'd start with yellows, greens and magentas before trying any others. However if your software can't do this even the global saturation/vibrance should draw the cloud structures out of the background.

I'd also ensure you target noise reduction as one of the first steps with these images so there's no sharpening of noise artefacts when you push contrast/tones. The image posted is too small to see how noise is but at ISO3200 there's going to be something there and masking as you reduce the chroma noise should get a good balance between noise control and detail.

Hope this feedback is of use, my apologies if the above is stuff you already do.

Tas

G'day Tas,

Thanks for your comments and advice. I've just been tinkering with PP but your guidance is very much appreciated.

Cheers
Frank
