Re: ZWO ASI-224 GAIN
Hi,
A value of above 60 is good for this camera because it takes advantage of the camera switching in to what is called a 'high conversion gain' mode which reduces the read noise. Other than that, I would suggest starting with your exposure at the right value (less than 1/30s or so) and then turn up the gain until the brightness of the planet gets to about 75% on the histogram – how far you have to go to do that will depend on your planet – much further for Saturn and for Mars or Jupiter for instance.
Hope this helps, Robin
PS.please avoid posting in all capitals – it is considered to be shouting and bordering on rude by many online forum users and you will certainly get more replies and engagement with your posts if you avoid it.
