8 panel mosaic Virgo Cluster of galaxies around Markarian's Chain - WIP luminance

As a test process to make sure the mosaic fits together, I have processed the luminance that Steve and I have collected to date: varying from 1.5hrs to 2hrs in each of the six panels. The weather is not co-operating much at the moment and a patient approach is required for this ambitious project through the galaxy season.

At this stage there is a fair amount of noise across the mosaic however the abundance of galaxies is clear and I have been amazed staring at my screen. Annotated image is included too for amusement: it is a busy image ;-).

Will update as data accrues!

Update: we have added 2 further panels, total now 8. This mosaic of the luminance does have quite a variation of subs in each panel so it is relatively noisy and with background gradient variations. It will of course improve as we gather further data. We have some RGB but lots more to do!

There is a splendid array of galaxy shapes and types so worth a view at high resolution . . . just forget the background variations.

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.
