What is the "Mono bin" button in my ASI air app? I'm using a color cam... ZWO ASI533MC Pro · Oscar · 3/2/2024 · 9 · 907 · 2

when I read what it was about in my ASI app, all I think I could understand was that it converts the color pixels and groups them and turns them into 2x2 bigger but monochrome pixels...

what's this for? and why so few people talk about it?

hi

not good basically low resolution imitation of a monochrome camera  ,Mono binning is an option for colour cameras, if selected, the color camera will ignore the information of the Bayer matrix and select the closest pixel value to merge and get a grayscale image. This will result close to the image of a monochrome sensor but it is important to remember you only get a quarter of the resolution.

The direct way to combat this is by drizzling 2x in that data's stack.

So my color camera can be a mono camera? That is the most unordinary sounding thing I ever heard in astrophotography.

I did  not know that this was enabled on my ASI2600MC Pro. I think a recent ASIAir update turned it on.

Anyway, I was not using binning. Are my captures still compatible with the color images that I took the next night with this setting off? I want to stack both nights together, but I am not sure if this "mono bin" from the first night affected those images.

Yes, I can't think of anything more absurd than this setting.

The 'mono bin' option gives you a 2x2 bin gray image.  It loses the Bayer matrix info.

Scott, I believe that you have lost the color information from the prior night, and you only have the monochrome grayscale info.  However, not all is lost with that data.  You could use it as a luminance layer for your RGB data - although it wouldn't make sense if you are getting your RGB data as 1x1 bin.

And for ZWO - I find that help diagram completely misleading, if not totally confusing.
