Title: Moon from last night
Post by: Rocket Pooch on Sep 17, 2005, 13:21:22
Hi,

Mosaic of 3x6mpix from an EOS300D, ISO200, 400th second LX90 F10, will get round to stacking them at some point, but this looks ok :-)

I nad to shrink the original a lot, its very ver big.

Chris,
Have you had a go at gettring the color out of it?

There is an atticle in the August S&T which talks about axagerating the color in luna images to show up the different minerals in the moon.

did you smooth this to reduce noise.....? looks like it's been put through NEAT Image - very impressive anyway - I would lkie to see full size..

Hi,

No smoothing, the reverse, just did a bit of a unsharp mask to show the highlights and also suturation to bring out the difference in luner colours.

It was 3 images bound in iMerge, with 200 feather setting because of the original 6mpix images the standad 20 pixel feathering would not work.

Will so a Ha, SII and OIII moon when I get some time.

What does it look like without the unsharp mask? I was puzzled that some of the craters looked so bright, and that the limb was so bright in places too, but the unsharp mask would probably account for both.

Hi Rick, the mark has contributed to some of it, but it really was bright and the right side of the moons was very very bright so even though I have dimmed it down a little there's still the brighter edge, I'll dig out the original one and stick it up here some time this week.  Also I'm trying to stack all the files I have (this is un-stacked) to bring out the detail, but at 6mpix per image I might have to load them into PS reduce the size then stack them, unless I can use AIP or something else to do the stacking, anyway that's another project.
