NGC891 - Outer limits - new version

New version with a reprocess of the background and stars

------------

I am happy to post this new shot composed of 2 different setups, the RGB come from my fisrt newton 10'' from the summer 2018, and the luminance from my new setup with the 12''newton .

The 8th of October in the evening, I just started the night as usual with some SHO subs because of the moon , and it shows good FWHM, so I decided to modifiy completly my schedule and shoot this very nice galaxy, after the moonset !

I had only time to shoot new Luminance but it was worth it ....

From Lacerta Newton 300/1200

56 Light subs @180s (gain 0 and -20°c )

From Lacerta Newton 250/1000 from summer 2018

15 Red subs @180s (gain 139 and -20°c )

15 Green subs @180s (gain 139 and -20°c )

15 Blue subs @180s (gain 139 and -20°c )

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.
