ZWO ASI camera gain

General
1

I have two different ASI cameras in my observatory, a 2600MC Pro and a 6200 MM Pro. I was curious, if you have an ASI, what gain setting are you using in the sequence settings? I am a fairly new Voyager and ASI user and was interested in what others are using for the setting. Thanks.

I have a 2600MM pro and a 2600MC Pro. The MC I generally use with gain 0 offset 50 for all targets and the MM with the same for broadband filters, and gain 100 offset 50 for narrowband.

Thanks. I’ll take a look at those settings for my cameras.

I have the 2600MC DUO, using Voyager and SkyX. Only had it for a couple weeks, but I started with gain 0 offset 0 - it was clipping at the low end and would not plate solve. I have it set to 100 and 50 now and it looks good, still has some plate solve issues (I think it’s a SkyX issue with color cameras). I’ll probably pull it back to 50, 25 after tonight to better preserve the dynamic range.

I’ve had a ASI 6200 MM pro since 2020. For most of my work I use gain 100 offset 50. High conversion gain lowers readnoise dramatically which is important for me as I usually shoot very faint targets. I also bin 2x2 so there is a dynamic range benefit. If most of my targets were fairly bright and I was shooting broadband, 1x1 Gain 0 offset 50 would be just fine. Definitely use Gain 100 for narrowband.

Thanks for the replies. We have been using 100 and 50 for gain and offset for everything but are trying 0 gain for broadband to see how that works for us.
