This is a quick comparison I made recently.

I have been using an OSC camera since I started imaging but recently bought a mono camera. The camera itself was delayed, while the rest of the equipment had arrived so I have been shooting NB data with the OSC camera for some months and using the Astro Pixel Processor debayer algorithms for extracting HA and Oiii data shot with an OSC sensor.

My mono camera arrived this month and I was able to reshoot HA data on a target that I had previously shot with the OSC, so I registered the integrations together to produce aligned HA images from both cameras to compare detail and noise. This animated gif is a comparison of the two. The cameras were an ASI2600MC and an ASI2600MM, both cooled to -10 and at 0 gain and an offset of 50, both are with the same HA filter and 1200 second subs, the OSC image is from 23 subs and the mono is 18. The OSC does not disgrace itself by any means but this certainly shows that the saying of "Never calculate something you can measure" holds true. Interpolation is no match for just reading it out.

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.
