Old Moon

Hi All,
This image was taken on the morning of 10/24, about 25 hours before new. Can anyone help me clean up the image? I have PS Elements, but I was unable to do any good. I also took 10 images hoping to stack them with Registax, but only 3 or 4 came out any good, and I had a problem with the large file size (the originals are 1.2meg files). Any help would be appreciated.

Hello Glenn!

How did you take this image? what equipment/settings?

I tried to work with it, but there's way too much noise and plenty of artifacts... it is a "little" rough to begin with...

We might want ot leave it "as is", since it does not look bad at all now...


Maybe any of the originals are "better" to work with?




Clear skies!

Hi Glenn, I played around a bit with your picture and I suppose you could get rid of the noise if you enlarged the picture. A second enhancement isolates the Moon from a median filter for the noise in this small format/size picture...
Keep up the good work!

You need noise reduction algorithms which photoshop type programs won't give you...you should take dark frames, subtracting them will give you much better results than noise filtering. Most of your noise here is from dark current, which is highly repetative image to image. Stacking multiple images will only reduce the random factor of the noise--the constant dark current and read noise won't be touched that much. You need to get rid of this noise before combining multiple images. That's what dark frames are for.

Thanks, everybody! I am going to try some of these techniques on the original - if I come up with anything worth posting, I will. What a great website and a great group of guys that are so generous with their time - thanks again! Glenn

PS - I think this is about the oldest moon one can see from the Houston area, because of all the humidity and haze, but I was amazed that it is nowhere close to the record!
