||Canon 60Da DSLR
200mm SkyWatcher f/5 Newtonian reflector with Paracorr for a total focal length of 1150 mm
||SCO, St. Croix, Nova Scotia
||Calibration and stacking done in Images Plus.
No darks were used in the calibration as my 60Da has built in dark suppression.
Masked stretching was used to keep the stars small on the initial
arcsinH stretch. Feature mask used to
split out the stars and the nebula layer was stretched with multiple
iterations of masked curves. LMS processing (see my processing tips
page) was used to increase the contrast of the nebula layer. Masked
additive colour balance was used to boost the red in the nebula image.
The star layer was colour enhances and then recombined with the nebula
layer. Masked RL deconvolution was used to sharpen the recombined image
and the final image was binned for web supply.
