M 51 from La Palma

I have run out of data to reprocess and no clear sky in sight until Thursday (hopefully), so I started to dig into the Liverpool Telescope archive again to see what data they have gathered since last summer (when Wim and I vacuum cleaned their treasure chest of unprocessed data). This is a remotely controlled 2 metre RC scope on La Palma (Canary Islands).

For M51 I found the following good subs to process: 55 x Bessell B (blue), 29 x Bessell V (green), 59 x sdss-r (red), and 3 x Ha. Subs varied from 30 - 120 sek, with an average of 90 sek. PI was unable to stack it properly (in my hands) so I had to resort to do it manually in Nebulosity 4. Then processed in PS. Data is from 20150312-20170812.

I have to say I am quite pleased with how it turned out, maybe except that it hardly fitted into the FOV, but what can you do with a telescope with a 20 000 mm focal length.....

Comments and suggestions most welcome!

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.
