I haven't been spending as much time as I should in my dome lately due to work and study commitments, but I certainly intend to soon as winter targets once again start to pop into view. 

I note that some of my latest work needs better noise reduction and being out the loop sometimes, I am wondering what software or techniques others here use for noise reduction? I used to use a program called Noise Ninja in PS, and it worked a charm, but the plugin stopped working with a PS update.

In fact, why don't I whine a bit more by posting an image I feel is noisy. Feel free to experiment or recommend software-

Thanks and look forward to the feedback.

Ray, I use the 'Camera Raw Filter' in PhotoShop. It's under 'Filter' in the menu.

In the image below I have circled the Noise level settings. I find it works best for me if I do Colour noise reduction first, then Noise Reduction, then 'Sharpening' last.

What I like about Camera Raw Filter is that you can raise Sharpening without re-introducing the noise you just reduced.

Thanks Prof. This is why I thought I'd ask, because its been a few years since I've done any research on noise removal and figured that there might be a new standard. If both you and Ken are both doing it, then it is most likely quite effective (and the results also speak for themselves).

Noel Carboni as you may know works for Adobe so has inside information on Photoshop. The noise reduction packages were tested and optimised on deep-sky images (as well as others) which is why they work so well on DSOs.
