MBM 54 and NGC 7497
MBM54 is very faint, high latitude molecular cloud of our Milky Way galaxy which is located in constellation of Pegasus. It was studied and surveyed by Magnani, Blitz and Mundy (hense the name MBM) in 1985 and now constitutes the MBM catalogue. These molecular clouds often called as Integrated Flux Nebulae (IFN) and are truly faint as they reflect residual light from our own Milky Way galaxy .
In the center of the image is an edge on spiral galaxy NGC 7497, which nicely blends with the clouds, but it is actually located much farther away . It is about 60 million light years away while MBM54 cloud is about 900 light years away from our Solar System.
Due to very dim nature of these clouds, they always present a great challenge and require many hours of investment as in imaging so in processing. My initial plan was to spend 3 nights for that object and collect as many hours as possible to balance luminance with chrominance data. We are often go much deeper with luminance and that could lead to cases were luminance data have no support by chrominance data, especially when imaging such a faint objects. Unfortunately for me, that is exactly the case, as second night was interfered by rolling in and out clouds and the third night was completely ruined by weather, leaving me with that insufficient data in RGB channels.
But, working on this image was no less intriguing or satisfying. There is always curious part to it when processing and that is to discover what I actually did capture in this image. While referencing to Simbad, NED and Vizier databases I could discover and mark more than 80 background galaxies in my image and that was worth the effort. Actually there is much more than 80 galaxies in the background. I created annotated version for this image while marking only brightest and obvious galaxies, but there is much more of them that look like a single stars so i didn't included them all.
