Heart and Soul Nebulae with Double Cluster and 21P/Giacobini–Zinner comet

Serendipitous capture of the 21P/Giacobini–Zinner comet (bottom left corner) while I was trying to image the Heart and Soul emission Nebulae together with the Double Cluster. It was an experiment because my DSLR camera is not astro-modified, hence it kills around 95% of the red light from the Nebulae. Being in a holiday in a relatively dark site gave me some hopes! Unfortunately the night was very humid and after 45 minutes dew started forming on the camera lens, so I had to stop the collection. Nonetheless I think the "experiment" was quite successful! With some tweaking using Photoshop I managed to pull some red nebulosity out of the two Nebulae's regions. The cherry on the cake was the unexpected capture of the 21P/Giacobini–Zinner comet (left bottom corner) which is now ca. 8 magnitude. Initially I though it was a shooting star that photobombed one of my light frames. After checking that it was in all the frames I realised that it must be real! A quick check on Stellarium and I found out it was indeed a comet!

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.
