Messier 81

My image shows grand design spiral galaxy Messier 81. At first sight it seems to be a quite plane, not well detailed galaxy lacking contrast, so I decided to photograph this subject as detailed and deep as possible. For this I made luminance layer with a small pixelled monochrome camera and I reused a deeply exposed image of the same area made by a canon DSLR as color layer. Also I made a few hours of exposures in H alpha to enhance the emission regions in the galaxy's arms. As a result I've got a highly detailed and deep image of Messier 81 and some high latitude galactic cirrus in the foreground. Thanks to the deeply exposed color layer even the farthest galaxy clusters on the image are colored.

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.
