Altair AA183M Pro, only additive binning

[Björn Arnold]

Hi,

With the Altair AA183M Pro (fan cooled), I can select additive or average binning when I use the Altair Software. Additive binning has the disadvantage that images are still clipped at 12bit. Please check if average binning can be added through the “native” driver.

@Stefan B - I see what’s causing this. All Touptek-like cameras, including Altairs, are affected. The SDK exposes a bit to enable average instead of additive. It’s an easy change, but changing this would affect images taken before a change. Let’s discuss in Discord what to do about this

Introduce a vendor-specific switch between the two types with the default being the current behavior?

[George Hilios]

Bjorn, unfortunately it looks like there’s a bug (or a feature?) in at least the Altair SDK. I don’t know how the other Touptek clones behave, but the Altair SDK clips additive binned pixels to the bitness of the camera instead of letting it go up to 16 bits. I tested this on an AA115M.

The fix for this wouldn’t be complicated otherwise.

George, the problem is not really that the additive binning is clipping at the bit depth of the camera. The major issue is that the average binning is not available. However, I hope that the average binning isn’t clipping the data before dividing by the number of subpixels.

In any case, do you think you can make the average binning available as discussed above?

Latest nightly has a switch for that on the camera tab
