M51 The Whirlpool Galaxy for 2022

This is my M51 for this year (so far). I hope to add more data if skies permit.

I captured 2.5 hours of data on 4-4-22 and added it to 4 hours of data that I captured on 3-21-21 for a total of 7.5 hours of integration.

I was hoping for more core detail. In my sky and fov, I feel that I need much more integration time to reach the level of core detail that I am looking for. I didn't want to over sharpen, so I elected for the wispy soft look.

I hope that you like it and thanks for looking!

Jim

Title: M51 The Whirlpool Galaxy for 2022 With Better Core Definition

Description: A friend advised me to try to get more definition out of the core of M51 and NGC 5195. I used a mask(s) on each core with a touch of HDRMT in Pixinsight. I hope that you like it!

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.
