Deep Sky Stacker Problem

[Ingo]

In deep sky stacker, I go in chose all my light frames, then dark frames. It does everything, registers the pictures, aligns them, stacks them...but when it gets done, it's just a blank picture? It's not white, it's just a grey empty box.

Am I doing anything wrong?

umm have you tried taking the result to photshop? there may be data there just needs adjustment to bring it out

Try sliding the RGB sliders to the left a bit. Make sure the little box that links them all together is checked so all the colours move at the same time. I adjust the saturation levels to around 16% and also you will need to adjust the intensity levels. But the best work is done in Photoshop or other picture editing software. Sliding the bar on the RGB will darken the image a bit so it wont look washed out. Give that a go,.

I found it sortta the same at first.. as suggested try the sliders... keep the colours together. move them right for lighter left for darker as a very general guide...have a play with the luminance also... keep at it...I find it works reasonably well.

Hi Ingo

I had exactly the same problem. The stacked frame from DSS is just very, very, very dark. The images that you have taken are there... somewhere.

What you need to do is heavily stretch the histogram. I use Photoshop and stretch the histogram using curves or levels (lots).

What type of images are you stacking? Canon RAW, tiffs 8 or 16bit, fits, jpegs, bmps?

Nikon NEF's. (Raw)

I'm not talking about it showing an image at all. It just shows a grey box where I guess the picture is supposed to be above the RGB sliders...like an error happened.

I went to click save, and it said there was nothing to save.

perhaps you can try posting the problem over at the DSS Yahoo group?

Have you tried stacking jpgs? Just convert few of your raws to jpgs and stack them and see if you still get gray box.

Or you can try stacking few raws but without darks?
