DSS help

[JohnSadlerAstro]

Hi guys,

I'm imaging M31 tonight, and I was just checking on how the data that I've gathered so far comes out while I took some more. When I stacked the shots in DSS, then exported the resulting tiff, the image appeared so dark that even an extreme (really, extreme) stretch showed the galaxy. even the subs look better! What's happening???

Not to worry, DSS often produces dark and almost monochrome images. It's normal to have to makes major adjustments to the colour curves and boost the saturation.

when in DSS did you move the RGB sliders once stacked? and if so did you save embedded or applied?

Or you can just bypass DSS adjustments completely and drop the stacked master straight into your editing software of choice (assuming youve saved it as 16bit). You will find it in the directory where your loaded the subs from (saves as Autosave .fit or .tif)

Thanks Guys!!! It's worked! I didn't check the 'save modifications as part of image' or whatever it is, box, so it was saving the modifications I was making, but not displaying them in the picture.

You should always check the box that says "embed changes but do not apply them" if you don't you will loose loads of the data, the image will be dark when sent to the editing software but that is perfectly normal, a few levels and curves will soon bring it out.

If you apply the changes that DSS makes it will clip the data and you won't have enough to play with, you don't want DSS to do anything with the image other than stack it, the editing should ALL be done in your chosen editing package.

I made the same mistakes till someone told me this

Hope it helps
