Description

I know this is not quite a "apple to apple" comparison, but rather my old vs. new camera test:

Left image: 10 minute uncalibrated and unprocessed image taken with Takahashi FSQ-106 AND 0.72x QE 645 reducer at F/3.6 + SBIG 8300M camera with KAF-8300M sensor cooled down to -10C. Filter used Optolong Ha 7nm.

Right image: 10 minute uncalibrated and unprocessed image taken with Takahashi FSQ-106 (w/o reducer) at F/5 + QHY600L camera with IMX455 sensor cooled down to -15C. Filter used Optolong Ha 7nm.

Nothing else was done to both images other than stretching them to the same level in PixInsight. Besides obvious SNR gain with IMX455, data from new camera was much cleaner and easier to process.
