M106

M106 - cold night, still lots of trouble with the mount post meridian flip losing a lot of subs and also stiff cables dragging.

but ... new mount (lockdown present to myself) the CEM70G is sat in my front room waiting for the tripod to be delivered. i will then strip down and service my NE6 and either sell it on or use it at my brothers (darker area) - yet to decide.

anyway - back to M106 - most of the subs were taken pre-meridian flip - and did ok. PHD2 multistar guiding is great - best guiding ive had in ages.

Description: Updated processing to
A) make sure selected appropriate Debayer pattern

B) did not use Bias - i think this had a big impact - as on original version i can see the thermal pattern in the top right (10% down on right edge) which the darks should have removed - but did not appear to have done so
C) used SCNR on the linear image to remove the green - this made noise reduction much easier and more consistant as it did not have to work around a mix of red and green
D) masked stretch also improved for same reason as SCNR - as it had a more consistant background to work from it was able to do a better job of stretching the image.
All the other steps were about the same - using a mix of starnet / range mask / luminance mask to isolate galaxy in order to tweak lightness and saturation a little after HDR / Local Histogram Equalisation.

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.
