A M51 PixInsight attempt, a BW image

Is there a visible difference between using PixInsight or Photoshop / CCDstack2?

Well here is my attempt to show a visible difference, if any at all :-)

In this BW M51 image PI processes SubFrameSelector, StarAlignment, ImageIntegration & DrizzleIntegration was used.

After SubframeSelector was used, like this,

PI SubFrameSelector

I had these files to work with in PI:

One Atik Horizon stack, LRGB frames: 116*2 (drizzle files included)

Second ZWO 1600MM stack , LRGB frames: 53*2 (drizzle files included)

The RegisStar program and a lighten Layer in PS was used to align & combine the two stacks FOV.

For comparison here's the Atik Horizon stack, a BW M51 image (it include also NB data) without the usage of PI,

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.
