Data source: Traveller


This is a 6 panel mosaic. Some parts have been published here before, some parts have been shot at this years cruise along the Canadian coasts an up the St. Lawrence river.

It is a free interpretation of my data: Bat and Squid nebulae are much fainter than the rest of the objects and according to this more of 32 hours of integration time were spent on these. For the rest, it is some 5 hours per panel.

One word about gear: Most of this has been shot unguided on a Star Adventurer. Only the NB pictures have been exposed on a guided CGEM. I used a trial version of Astro Pixel Processor for creating the mosaic and I am very much impressed with it. If for nothing else, I think I will stay with it for creating mosaics.
