NGC 7000 mosaic
Posted 11 March 2013 - 12:11 PM
The photos were taken in August 2012. The sky conditions were very nice, when I was taking the first plane. When the second plane was beeing exposed, the sky became grey as a thin layer of clouds came. Furthermore, the photographed field approached dangerously close to a source of light pollution. This frame indeed came out a little foggy. Fortunatelly, the calibration function of Registar worked well, so the colour matching of the two frames succeeded.
And the result is here:

The cut-out of the most interesting part in Hi-Res.
Pentax 6x7 camera, Takumar 400mm f/4 @ f/5.6, Kodak E200, both frames 55 min, Iron Man setup.

There is a smudge which I find in the hi-rez cropped version on Michal's frame that I've found on mine as well but never tried to identify it. Lower left side looks like a smudged V near the border.

Igor, it is developed normaly - no pushing. The left side is actually the left side of one of the fames. The right side was cut to make the composite rectangular. How about the chromatic aberration of your EDIF version of the lens? I guess it should be much better in this regard. I faded the blue and red fringes in this image by desaturation in PS.
