Dark corner of image

[CFG47]

Can some-one tell me why just occasionally in a run of images I get subs that look like this.  then goes back to normal the next sub. 

Ignore quality of image as this is just a screen print off of remote connection to show you what I mean.

Just to clarify, this is a 10minute fits file just as it downloaded.  The rest of the subs are OK.

Lots of views but no ideas?

CFG,

If this is a 383L would it be that the shutter is sticking?

Thanks Joseph, that is what I was wondering.

CFG,

The more I look at the picture it certainly looks like the edge of the shutter.  There is a prior topic on the sluggish and/or sticking shutter.  You may have to contact Atik for a solution or send the camera back for service.  I hope you are in Europe because shipping from the US is expensive.

Thanks Joseph.  I'll contact Atik then. 

Thanks
