Hi,

Yes it does. I can get the noise down quite a lot with that method.

Thankyou very much.

Great idea, never used it before but this is the link to the 36Mb full tiff

https://www.dropbox.com/s/vzns50qc24bed ... ivers.tiff

And a baby version: https://www.dropbox.com/s/ryxca4nrfs0cs ... _crop.tiff

Sorry it's a bit small but the limit is 512kb and that doesn't go far in TIFF land.

I used the upload attachment but I can't see it - I hope you can ?

I've attached a small fragment of the image showing the issue.

Hi,

Is there an easy way of removing the 'rivers' noise patterns that are prevalent with one shot colour cameras (both cooled and DSLR) ? In my case the image is of a star cluster which has no surrounding dust or nebulosity. These systems can be very fussy when it comes to darks.

Thanks
Robert
