About this image

H-alpha data only - image looks sharper than when combined with unfiltered colour data.  Calibrated, stacked and processed as before.  Looking forward to imaging other large summer nebulae with H-alpha and duo-band (H-alpha and OIII) filter.  Main challenge is that raw images are drowned in Milky Way stars that need to be toned down to reveal fainter nebulous regions.
