Bubble Nebula, M52 and NGC 7538 (Ha)

The Bubble Nebula (NGC 7635) right of centre, Open Cluster M52 (NGC 7654) lower right and NGC 7538 upper left.

Shot from my back yard observatory in Fremont Michigan over 2 nights, the 23rd and 25th August while the moon was high this is my first attempt at shooting in hydrogen alpha using the Canon 5D Mark II. Consisting of 51 x 10 minute exposures. Totalling 8.5 hours. I added a layer of luminance during final processing in CS3.

I had intended to add a similar amount of subs in OIII but things dont always go to plan do they. Oh well perhaps next full moon I may add some more if the weatherman sends some clear skies.

Thanks 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.
