Rosette Nebula
 
I wish I had taken this picture, but actually, it is my dad's picture from Spain.  However, the processing is mine.  Already applying the latest tips and tricks from Neil.
 
I don't have a lot of technical details about this picture, but here they are:
 
- EQ6/Atlast Mount
- Quadriplet Refractor 80mm FL=480
- Canon 20Da for image adquisition
- Guiding: PHD on similar setup to ST-80
- Darks were automatically added at the time of taking the picture
- Total luminosity/sub exposure is 1 hr.
 
RA= 6:33:59
DEC= +04:49
 
Now, for Processing, I used DSS (no darks, no flats, no bias) just high res. JPEG's that I received in a CD-ROM over snail-mail from Spain.  I used Photoshop, Carboni, and GradientXTerminator for processing.  I was able to identify a G type star for white balance, so that made color calibration a lot easier but it was pretty much an effort on Levels and Curves stretching and massanging it.
 
 
Enjoy it!

Neil,

Thanks a lot Neil! This is a dad and son teamwork going on here. :)

How would you increase the contrast in the center? RGB Curve stretching?

Thank you!

Miquel This is a fantastic shot. Looks good. Very nice star color too. You could perhaps increase the contrast in the center where the dust lanes are, but overall, it's an excellent shot. Kudo's to your dad for the great shot and to you for the great processing.

-Neil
