The molecular cloud visible in the image with the unspectacular name LDN 673 is located at a distance of about 500 light years in the constellation of Aquila.
The abundance of stars in the background - which give the dark cloud its strong contrast - is so high because the object is located right in the Summer Milky Way, a spiral arm of our Galaxy.
This image is the product of another collaboration between
@Marcus Jungwirth and me.
Right after our last project - WR134 - I decided to use another moonless and clear night to start collecting luminance data on LDN 673. While I was posting the first sub exposure in our collaboration group, thankfully Marcus decided to join in on this object, and he did a great job as always!
Marcus collected 19! hours of RGB data with his QHY 268C and his 8" Lacerta Photonewton while I collected another 9 hours of Luminance data with my ZWO ASI 2600MM Pro and my 10" Lacerta Photonewton.
Even though it was quite challenging to put the two different datasets together (mainly because my luminance had some weird gradients on the lower part of the image), I really enjoyed processing this image and I'm quite happy with the outcome!
