Why would you limit yourself to the cheap optics and low resolution of a p900 when far better option exist? It has a tiny light gathering capability (the actual size of the lens element) and a small sensor, not well suited to this kind of imaging. It's no surprise it doesn't do a good job. That's why anyone who is serious about astrophotography has a telescope like I linked earlier, and an slr or milc camera with a larger (APS-C or full frame) sensor for image capture. The p900 is a toy vs what people use for capturing actual good astro images.

Once again I refer you to the images captured by Con Kolivas, you may know him, he was the guy who wrote cgminer, contributes to the Linux kernel, and does some amazing astrophotography, in addition to being an Anesthesiologist.

He's here on Nostr too. You could probably learn a thing or two from him.

Could you tag him please?

I already did a few comments back. I'm not going to spam him with more notifications of this silliness 😂

Appeal to authority fallacy. The p900 and the newer p1000 do a great job and i have seen some amazing footage with them. You still cant unprove the results of these cameras. Try harder gimp.
