Question on ASI120MM camera.

[iansmith]

Hello,

I'm thinking about purchasing a new planetary imaging camera and I am looking at the ASI120MM. I know that it has fast rame rates (113fps) at 640x480. What I can't find out from reading around is if the 640x480 mode is just a smaller part of the CCD or is it a result of binning the pixels. Does anyone know?

A fast frame rate with a (binned) pixel size similar to those of the DMK would be ideal for me.

Cheers,

Ian

Hi Ian,

I'm no expert but from what I've read about the ASI120MM it uses software binning rather than being implemented in hardware. Here's the link:

Hi Glenn

you are correct,the binning is implemented in software level.

the chip did has a bin function.

but works not nice. So I didn't use it

Hope that helps, I've got a ASI120MM and I think its great. Still a beginner mind you though

According to this site:

http://www.zwoptical.com/eng/Cameras/ASI120/index.asp

It support binned 640x480 at 35 FPS and 640x480 non-binned (just a region of interest of that size) at the higher frame rate of 113 FPS

The latter is the most useful: you look up the planet at full resolution, and then choose the part of the full frame you need. I do the same in my ASI130MM
