Help with dithering



Not sure if this is the right category to put this under.

I’m not sure what parameters to type in under “Dithering”

I got a Nikon D5300 DSLR at 1,57 arcsex/pixels
and a Zwo Asi 120mm mini as guidecam, at 3.75 arcsec/pixels

Now what do I type with these two cameraes?

Best regards,


What scope sizes and focal ratio are you using with each of them?


It is a Sky-Watcher Evostar 80ED, with a 510mm focal length with the 0.85 reducer, I use with my Nikon.
My SW 9x50 Finderscope is 180mm I believe, which I use with the Zwo


No one knows? :slight_smile:


Hard to know exactly. Start with some sain values and go from there. Maybe medium dither and settle below .25 pixel or so as that will be half of your imager. Then settle for 3-5 seconds.



Hi Jared

Thank you, I’ll try that.
