West Veil nebula and Pickering's triangle

AstroDMx Capture was used with an SV605CC OSC colour CMOS camera and an Altair Starwave ASCENT 60ED doublet refractor with 0.8 reducer/flattener and a Pegasus Focuscube v2. An Altair 2” magnetic filter holder version 2 containing an Altair quadband filter was placed in the optical train. 24 light frames of the West Veil nebula and Pickering's triangle, 5 dark frames, 50 bias frames, 50 flatfields and 50 dark-flats were captured. The data were calibrated, debayered, stacked and part processed in PixInsight and completed in GraXpert, PhotoDemon, Photoshop CS2 and Gimp. A Pixinsight Cosmic Photons script was used to Generate a Hertzprung Russel diagram of the stars in the image.
