M51 - The Whirlpool Galaxy

Here is two photos of M51 (the Whirlpool Galaxy). First one is just quick attempt from Carpathian trip - LRGB (10 min each filter) - the first night near house ( huge humidity was there). Second it was first light of my travel scope from Holodniy yar near Kropivnitskiy - one shoot 120”. I try to compare two cameras result especial from start size perspective. I have some feeling that asi1600 should give more details because of pixel size 3,8 against 4,29 on Canon. One respected man told me that atmosphere in Ukraine blurs details so it does not make sense try to go with smaller pixel size. Going to check this statement to make side by side compare at the same setup/same time/ same total exposure time - but it is task for future. Here is just first steps to learn new equipment and processing techniques.

First shoot:

Telescope: FRA400 72/400 quintuplet

Camera: ASI1600mm pro(-20)

Lights: LRGB 10x30” for each channel ( 5min total exposure)

Darks - 10x30”

Second shoot:

Telescope: FRA400 72/400 quintuplet

Camera: Canon 60Da

Lights: 1x120”

Darks - 0

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.
