This 90 megapixel image is the result of a cooperation with 3 fellow astrophotographers,
@Sara Wager, Dominique Dierick and
@Kees Scherer and myself. It all started in 2017 when we worked together on a larger mosaic of part of the Cygnus constellation.
I would recommend to strawl through the image to find all the details.
Last year (2021) I wanted to make a nice image of the Tulip Nebula (SH2-101) and the nearby hydrogen clouds so I made an image stack consisting of 1 panel of this region. This summer (2022) they predicted a longer period of clear skies and I decided to extend the field of view to get more coverage of this very interesting region.
After finishing this image I noticed that I was very nearby the Crescent nebula region and knew I had a lot of data of that region also, so I decided to look onto my image archive to see which data there was more region and that was how I stumbled onto the mosaic data again that we all captured in 2017. It showed that with this data a very nice field of view could be generated with full coverage from the Tulip up to far above the Crescent nebula. Because of the high quality of the data processing was very easy and that is what resulted in an 90 megapixel image of 4,5x6,2 degrees of sky area.
On my webpage you can find a lot more info and details about the image:
