Has anyone tried the new -25 gain setting on these cameras yet? Just curious if there is any real world experience in regards to any issues such as increased banding or artifacts. Some older cameras like the 183mc pro did not work well at maximum FWC, but that was also at far below unity gain, but they did work well at half unity gain. I know that this setting allows these 2600 cameras to finally achieve unity gain while upping the read noise a bit and an extended FWC. Just checking before I build a new calibration file library for doing broadband targets with fast glass and no filters…as my skies will not allow me to test right now and have been cloudy for over a month now. Thanks in advance.

sensor i did a few tests myself and did not notice much either but mine is not a duo with the bigger faster memory. I did notice a bug that switches the gain on the main page from -25 to gain 0 while imaging and previewing. Files still show -25 when saved.

Tech@ZWO it was a bug in asiair to control my 2600mc pro. This was using the new asiair beta testflight. During image aquissition in preview or autorun it changed to 0 gain from -25 in the main page.
