mosaic of the Antares region
« on: 2011 November 16 11:39:30 »
Hi

first attempt to make a mosaic of 9 frames from the Antares region at this summer 2011

Optics 180 Epsilon f2,8 and a QHY12 Color CCD.
9 x10 x600 sec during several nights in June 2011.
I still have some gradients near the image borders, but at the moment I'm quiet happy with my first mosaic.

Edmund,

Your first attempt of a mosaïc is quiet impressive, the panels have the same levels an everyting is pingpoint, really nice!    8)

The only thing that could be changed IMHO, would be to more restrictively proceed with the DBE tool, perhaps a SCNR to supress some greenish touch an finally a manual Histogram stretch to "calm down"
the background, these applied to the finished merge..

Edmund, great Job on a 9 panel mosaïc, what is really not easy game!
Clear Skies!!

Lex

Hi Edmund,
Nice mosaic. You can try attached process in order to reduce a little crominance and green noise and to highlight dark nebulaes

Saludos.
Alejandro.

Wonderful image Edmund.  Congrats.  If you live were gradients are present, you should learn the DBE tool.  It works very well.  I have to use it with every image I produce from home and is the only reason I can do color from my backyard.  One tip when using it.  If your images cross the meridian, your gradients will change.  Either plan to image on one side with a particular filter or stack the individual frames from one side at a time and correct them first prior to combining them.  It makes gradient correction much easier.

Yes, save the attached process, drag it on Pix workspace and then apply it to the final picture that you posted.
Let me know if you have any doubt.

This is a great image Edmund! The first one was good and the second is really beautiful! Well done.
Is there a little artifact from the GradientsMergeMosaic process on the second brightest star in the upper left corner?

Best regards,
Ginge
