Taken last night.


I am surprised I managed to tweak this much out of the subs considering how bright and high Mr Blobby was last night.


 


GT 81


Canon 350 D


 


45 X 180 second subs at ISO 800


11 Darks


21 Flats


21 Bias


 


Stacked in DSS


Pulled pushed and generally beaten up in PS 6.

Graham, i am not sure as i am not a geek, but your stars have holes in then like a donut???


does this mean you have pushed/pulled a little to far, or is it something else?

Hi Sheila

You are spot on about the donuts.

If anyone can shed some light as to why I have this weird effect please advise.

I noticed it is on the coloured stars the larger white one seem unaffected.

Stephen has sent me a link to a post from someone with exactly the same issues.


It would seem to be created by a setting in DSS.


I will re stack this using another setting and let you know if it works.
