I would guess that the image itself as captured is actually pretty good. There's quite a bit of detail visible.

But the Lord only knows what that auto-sharpen has done to it.

Edit: if you'd like me to have a go at editing it as I did with the one in this thread, upload the unedited version.

It looks a little noisy, is that caused by the sharpening?

I'm quite impressed that you've managed to get the colours, my moons are always grey / white.

It would need a bit more attention to avoid the exaggeration of the bright edge in the high pass filter, but I only spent a couple of minutes on it.

As Woodworm says, getting the colours like this is pretty good.

A bit less exposure next time might reveal the detail on the Tycho side.

By the way, I resized this to 800px... on my browser (Firefox), it gets enlarged, which makes it look worse. Click the image to open it in another tab if it does this on yours.

I think it was MattMatic that first posted the technique here, so I can't take any credit for it, but I do find it works well for moons.

- Duplicate layer
- on the copy, high-pass filter and aggressive sharpening
- convert to Overlay
- adjust opacity to taste
- merge layers
- reduce size by about 10-15%
- tiny amount of USM to finish

In your case, I increased the saturation in the original layer till I could see the colours.

Brilliant Chris had a go and it worked much better than my feeble first effort.

Damn!

Everyone will be doing better ones than me, now

Thanks for the excellent tips, my first effort.

Well it's superb, obviously. In terms of visible detail, it outclasses any that we've seen here recently.

There's not much information in the EXIF - would you care to share how you created it? This is a C&C thread, after all, not the gallery.

Yes i would be interested too.

It was a thanks for the processing tips that was really the point of my post. It is taken with the K35mmf3.5 through a telescope eyepiece. It's about as good as I can get with a single shot and all of the Moon in view. There is some softness towards the edge and I think that has to do with the setup and not atmospheric haze. I'd like to do it better and the next step will be to stitch together a series of closer views, which in theory should produce a decent result.

With respect, you can hardly be surprised if a different purpose is inferred, otherwise why use the opportunity to showcase something that is clearly enormously superior to the rest of our meagre efforts?

If you've benefited from the processing tips, it would have been nice to show the before and after processing of the image concerned, and it would have been even nicer if you'd felt minded to share a little more of the detail of how you took it.

I have no experience with telescopes, yet I'd love to be able to create an image like this, so a little more information about the setup would have been much appreciated.

Forgive my ignorance, but what effective focal length does the lens and eyepiece give you? Is it the sort of thing that can be purchased without great cost? Is it easy to set up, or is a specialist adaptor required?

Of course, I could have just kept the editing details secret... maybe I'm just hoping for a bit too much of the community spirit here.

I'd be happy to answer your questions if you could put them in a civil manner and I have discussed the set up in other threads but actually I can't be bothered to respond to that continually aggressive tone.
