Veil nebula mosaic

Veil nebula mosaic from two different telescopes: On the 13th July I was able to add a further 3.3 hours of HO data of the Veil nebula using my Altair 60EDF doublet refractor to fill in the blank areas of the mosaic I did on the 10th July using my William Optics ZS71 doublet refractor. The additional data were then combined with the original data set to produce a seven pane mosaic comprising a total of 5.8 hours of H &O data which was integrated using the HOO palette. The final image covers some 3.3 x 3.3 ° area of sky and encompasses nearly all of the nebula with the mosaic being made using Pixinsight's “Merge by coordinates” script and the “gradient merge mosaic” process. This supernova remnant covers an area of sky almost 6 times the diameter of the Moon and is the left over material from a star believed to have been 20 times larger than the Sun that went supernova some 10 to 20,000 years ago. From the initial supernova explosion the material is expanding at a rate of 1.5 million Km per hour, so from my original data taken three nights previously, the remnants have expanded another 67 million miles!
