Update:

here is the "raw" PI drizzle image,

NGC4631-raw-DrizzleIntegration-All-Frames

Here's the image after I have processed it in PS,

PS enhanced Image

Above images was then used as a luminance layer is PS -> ImageV3.

I have not yet calculated the total exposure time of the drizzle integrated 324 images, a manually task.

Org. text:

Expect this color picture of NGC4631 to be my last one for this astro season, summer is approaching fast in DK.

Exposures done like this:

20 April-2018, R=38x60sec, G=36x60sec, B=42x60sec.

21 April-2018, Ha=6x300sec, OIII=6x300sec, Lum=52x60sec.

22 April-2018, Ha=10x300sec, OIII=11x300sec.

My home build observatory is placed in my front yard/in the "red light" polution zone, have a look here,

Red Zone

Stack info. available (as 16bit Tiff) if needed/on request.

Kind regards Niels

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.
