Wow! Very very nice......
You've probably said many times before, but what were the capture details Bert?

Does that red nebulosity below the Lagoon have a name?

[avandonk]

It was taken with the Canon 5DH and Canon 300mm F2.8L at f/5. All at 400ISO.

Fridge at -10c, EQ6 guided with Guidemaster with dithering.

Exposures 20x (1 min, 2 min, 4 min) and 15x8 min. Hutech LPR filter. Sky was very clear.


Raw images corrected for flats and darks converted to 16 bit fits. Fits were then stretched and converted to 16 bit tiffs. These tiffs were then upsized by a factor of 1.5 (75MB to 160MB).

I started with the shortest exposure set and worked up from there. This has the effect of obtaining higher real resolution than that of a single frame. Registar was used to median stack these sets of exposures. EasyHDR to produce the final tone mapped image from these four exposure stacks.

If you look at the resulting image there are two things that strike you

1. The dark lanes of dust have intensity detail.

2. You can fill out the rest but there is more than two.

Good one Bert

EXIF declares the authoring software to be CS2 Bert. I thought you'd gone CS4 64-bit?

[avandonk]

Has not arrived yet! My major limitation was not PS but ImagesPlus. The 64 bit version is amazing. You can use almost unlimited file sizes 500MB tiff files anyone? PS is only good for a tiny final tweak and not much else. IP 64 bit can run more than one operation at once. My previous computer would not respond with only one operation running.
