The Pelican and the Eagle nebulae

In this imaging session we were testing a new autostretch display function in conjunction with our non-destructive DMx white balance in Nicola's AstroDMx Capture.

RAW, 5 minute FITs files were captured with AstroDMx Capture. 60 minutes worth of data were captured on the Pelican nebula. The scope was a WO 81mm APO refractor with an Altair Quadband filter and an Altair Hypercam 533C 14 bit OSC CMOS camera. The data were debayered, calibrated, stacked and part processed in PixInsight and further processed in the Gimp 2.10, GraXpert and ACDSee. The Final image was rendered as RGB and HOO-RGB blend.

RAW, 5 minute FITs files were captured with AstroDMx Capture. 65 minutes worth of data were captured on the Eagle nebula, M16. The scope was a WO 81mm APO refractor with an Altair Quadband filter and an Altair Hypercam 533C 14 bit OSC CMOS camera. The data were debayered, calibrated, stacked and part processed in PixInsight and further processed in the Gimp 2.10, GraXpert and ACDSee. The Final image was rendered as RGB, HOO or a blende of the two.
