ASI120MM-S sporadic glow

mpyat2

Hi everyone,

I've recently bought ASI120MM-S camera (primarily for planetary imaging) and tested it in long-exposure mode. In general, the camera works well yet there some glitches: there is sporadic glow (occurred occasionally, approximately in 3-5 pictures of 100). I've attached an example of normal frame and a frame with glow (both are darks -- with closed cap). As I already note such frames with glow occurred sporadically in a series of images.

Is it normal? Is there a way to get rid of this?

Exposure=10s, Gain=29, images collected via SharpCap with the native driver, USB2.0

Best regards,

Max

Hi Max,

Sorry to tell you it is normal for 120MM-S and cannot be fixed now.:(
