Widefield Milky Way Mosaic from La Palma

This is an image that has been around a year in the making.

From the initial gear selection and acquisition, extensive testing and adjustment, location and target selection and planning, transportation of the setup, data capture, and finally a pre and post-processing marathon, this has been by far the most work I've put into a single image to date. It has been a journey, and I think the end result was well worth the effort!

Unfortunately we had unusually bad weather for La Palma, so I didn't capture as much data as initially hoped. Thankfully my sequence was set up so that my acquisition was balanced across all panels, meaning I had enough data to make a full image after one full night, and subsequent nights only added to the total data captured.

The image comprises 8 panels of HaLRGB data, all taken at f/2.8. Captured at 19.74"/px the image scale is relatively coarse, but after drizzling the full image is still over 550 megapixels. The version uploaded here is 25% of the full drizzled resolution, or 50% of the native resolution, due to image size constraints.

Any CC is most welcome! 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.
