Re: APOD: M57: The Ring Nebula (2012 Apr 20)

I like the contents of the image but in my opinion the processing is way overdone. I think much more detail in a softer way can be shown. But that's a personal opinion.

Re: Hubble's Hidden Treasures Contest 2012

Hi Geckzilla, You're really making great progress. I see improvements with every image. Nice to see that. I also have processed some more galaxies I would like to share... I think this is a great topic and hope that much more people will tag along during the competition! http://farm6.staticflickr.co...

Re: Hubble's Hidden Treasures Contest 2012

I didn't keep the file, so I don't have the larger version here now. I only used the same data as Geckzilla did before. No ACS data was used here (it doesn't exist for this galaxy). The trick is in using a proper ddp to stretch the image to its max.

Re: Hubble's Hidden Treasures Contest 2012

Hi Geckzilla,

I also took NGC 3185 to see what's in the image. I think you will be able to get more out of it. What software do you use for processing? Maybe I can give you some help... Here is what I got out of it.... (just a quick and dirty approach :) )

Re: Hubble's Hidden Treasures Contest 2012

Go look for the ACS data and use the WFPC2 as color info. There is some great images in the ACS database, and they are much less noisy. Or look for narrowband imagery, they are also less noisy.....

After the nice remarks of Ann (thanks for that) to my previous post I update my M77 picture with much better colors I think. Here it is.

Re: Recent Submissions: 2012 April 5-

Well, this was my hardest job until now. Combining the different datasets to get equal colors was really hard. M77 was not fully covered by one dataset, so I had to combine channels of the WFPC2 with different wavelengths and tune the colors to get them to fit. But the result is in my opinion quite ...

Re: Hubble's Hidden Treasures Contest 2012

Browsing through the hubble legacy archive I found this beautiful area that was imaged in 2006. I didn't find any nice hubble palette image of this area, only an image showing the area in bicolor, with less detail. So I decided to make it myself :) NGC 6357 Nebula HST imagery http://www.astro-photo....

Re: Recent Submissions: 2012 March 11-

After some reprocessing my moon mosaic got to its final result. It consists of 107 images and is 18mp large. I think it's one of the largest and most detailed moon images made by a single observer using a series produced (c11) telescope. The image can be found here: http://farm8.staticflickr.com/705...
