Deep sky Stacker use with a modified DSLR

[John K]

Hi guys,

I am having issues with using my modified DSLR with Deep Sky stacker in terms of getting the right colour balance.

In all the DSS manuals that I have read you have to line up all the RGB curves. Well, with a modified DSLR obviously this does not work!

As well, the output is in TIFF, so once you get this in Photoshop you are stuck with that output unlike with a RAW file.

Is the answer simply to much about the the RGB curves in DSS and remember the settings? Or is there another process that should be used?

Thanks in advance,

John K.

I don't use DSS for colour processing, that is better done in Photoshop in my opinion. Its true DSS saves in 32 bit TIFF but Photoshop can open it as camera RAW.

[John K]

Ok thanks - just forgive my ignorance, but if DSS is saving it as a TIFF file, when I open it in CS3 I do not get the same dialog box as when I open a RAW file. What am I missing here?

Hm, too many versions for me. I use Elements 12, don't know CS3. Anyone else?

Hi John
you can align the colours in DSS under one of the settings. Use it all the time with my CDS.
Cheers Andy.:)

Yep - you can simply align the RGB curves - BUT if your camera is modified this does not appear to work correctly.

That's the issue that I am finding - so perhaps I simply have to remember the settings that give my camera the best colour balance and use this all the time?

hi john,

I simply import the tiff file into photoshop. when working the levels and curves I unselect RGB and choose red, work the curve / level then select blue etc. It generally ends up balanced.

hope that helps.

cheers,

russ

thanks Russell, will give that a go - looks simple enough even for me to do!

I always found working with colours in DSS really harsh, gave it up and just used PS long ago.

As for importing into PS, it comes over as a 32bit TIFF, just go to Image>Mode and change to 16bit and select Exposure and Gamma then OK.

I play with all the sliders in DSS until I like what I see. then open saved image in CS5. Add touch of vibrance, curves and done
