Cocoon Nebula

The Cocoon Nebula in is a often imaged, obscure patch of hydrogen alpha and some refection elements located on the outskirts of Cygnus near Lacerta. It is a dusty and dirty are of the sky sitting in a dense star field. I was imaging in Ha during a full moon and running quick stacks every 5 hours of integration to see how deep the Ha went. I knew there was decent Ha in the background but I was surprised at how much was actually there. I ended up stopping at 25 hours worth of Ha as I started to see the limit of what I could capture. After the Ha was done I went after the "foreground" dust. There was a lot of it! With just over 500 exposures with luminance, it almost filled entirely the frame with faint dust. I had to stretch the image far less or the whole image be dust. It is a very contrasting image with many elements. The background Ha being obscured by foreground dust and the bright Cocoon nebula with some reflection nebula surrounding it. I plate solved with the PGC objects showing up as I was able to capture many faint fuzzies in the background. Tour the image and you will see some of these small hidden gems.

Its a little different version of the Cocoon, but I wanted to try and get all the elements into one image. The wide field allowed me to do this at the expense of some of the finer detail in the Cocoon itself. However, looking at the Cocoon it seems to be obscured as well by dust and seems soft in most image out there. The finer detail may need some processing that is above my level to bring out.

Thank for looking

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
