ASI120 as whole sky camera?

tomb

I kludged a a simple weather-proof version with included (120 degree?) lens. Helps me decide whether to fire things up and head outside...

1) Is there wider "fish-eye" lens that would approach 180 degrees FOV?

2) Is there a commercially available case/dome optimized, or at least know to work with / fit the ASI120?

Thanks!

We have these lenses, do not have cases.

There are some people doing this project, hope this would help you.

Apologies for hijacking the thread.

I use a 120 MC USB3 version on an all sky cam. It suffers badly from fixed pattern noise, even with exposures as slow as 10 seconds. Using allskeye software on windows I can mitigate some of the fpn using a bad pixel map, but it's still a spotty image.

Is there a more efficient ZWO camera ( colour ) anyone can suggest, that will allow 30-40 second exposures without significant fpn? I'm in a bortle class 4 area.

I use a 1.55mm f2, CS mount, lens, provides a 200 degree image circle - rather than the usual accessory from ZWO.

We have more efficient cameras for your reference, such as ASI224MC, ASI290MC, and our new camera ASI462MC. They have lower readout noise than ASI120MC.

Thank you - That final one doesn't appear available at my usual UK outlets...

We are sorry to hear that, the ASI462MC is our new camera, it has a few stock. But we will produce more cameras for sale.
