ST-8300 image settings - where did the nebulosity go?
The attached screen shot, starting from the left - a single light frame of 6 minutes, taken under moderately light polluted skies. The middle a 6 min exposure at a dark site.
Cropped - the image on the right is the calibrated, debayered, registered, integrated result of 34 frames - a total exposure time of 2hours @ -20C, 200mm Canon prime, stopped down to f/6.
Is the obvious lack of nebulosity a case of truncated pixel values or is it a processing artefact.
Regards,
Rowland.
