hi guys,

maybe some of you might find this useful.
It is a tecnique I use for a long time to boost colors in my astro-images without picking up any color noise.

hi guys!

after posting the color boost tutorial, here is anice and slick way to boost contrast in your astro-images.
however, you must be more precisely in determination of the adjustment-points for boosting contrast. but then - it works perfectly well!

hope you find it useful.

hi guys,

to achieve relastic colors is what we are eager to obtain in all our astro-imaging efforts, isn't it? however, the question would be: what is realistic? what is objective ?
and what is feasible in color-imaging?
I have witnessed many discussions about the "true colors in LRGB- and DSLR-astrophotography" that repeatedly have taken place all over the globe in different forums at several occasions and frequently yield a result which clearly misses the punch-line of human color-sensation.
You might have attended some astro-imaging conference where a couple of well renowned imagers have presented their photos of maybe the same object and claimed to have gotten the "right" colors. And has there not been a huge difference in the appearance of such photos? Naturally! Because the the most important factor in color-composition is us.
here are some thoughts about colors in astronomical imaging:
a bit of physiological and philosophical background from my standpoint as physician and photographer.

hi there,

I have attached an image displaying my scopes an me.
the main scope is a 9" f/9 Tmb Apo designed as folded refractor.
secondary scopes are: 5" Tmb Apo f/9 and a Solarscope from Coronado (<0,5A)

I use the Tmb Apos for planetary and lunar imaging as well as for deepsky imaging.
the coronadoscope of course is for h-alpha observation of the sun.

find some pics taken with these telescopes here:

PS:
Alan, Your planetary images are really awesome! hot stuff!!!

Larry, Enrico and Alec,

thanks for welcomining me so nicely!
I hope I`ll be able to supply some good images, soon.
best regards
DIetmar

...that one is a beautiful shot, Jim!
the best so far regarding to the past images.
well done!
best regards

...that is quite a load of details on this difficult object, Paul.
congrats!
I`d like to know what focal length You used?
what about pixel size of the orion star shoot?...sorry no idea...
bes tregards

ps: I see You own the same plantetary camer as I do - lumenera 075c...I think we should talk about that camera and its settinggs later on...?

hi C

I use DMK 21F04 with the original IC capture software 3.0
and I can say I`m most content with it.
it is a reliable programme.

see some results here:

well done.
I like the DMK!

Whow!!! that`s impressive, Roland!
