how can i fix an image with drift in one direction?

[h0ughy]

i had over 4 hours worth of data - all done after my win 7 guiding setup turned off the usb port my guider was using (yes i left it unattended) and i dont understand how it happened, must have been reset after an update? .  any clues on how i can save the data or is this nights effort wasted?  just did a quick lift in histogram to see the errors

thanks Carlos - very quick response.

for a newbie how would i go about weaving the magic?

Try deconvolution with the motion blur PSF, play a bit with length and angle to find the correct.
But I think this may save the stars but your subject will be blurred anyway

I can't help but if you try and make headway with the suggested motion blur PSF please post back with your workflow.
I've wrestled a little bit with this and came up lacking.

I will borrow your image naming convention ... applies well to many of my images.

I've tried the motion blur deconvolution too and it never seems to work for me or rather it works, but not the way I want it too! I use morphological transform using median and a size of 7, then depending on the motion I darken the pixels to remove the motion. It takes some experimentation and is not a 'magic bullet', but with a little work and Pixinsight magic, it can do a 'reasonable' (YMMV) job!

My usual response is to forget about salvaging the image and instead see what I can do to prevent it from happening again. No amount of post processing can recover the data lost due to smearing. I mean if you're desperate the salvage something from the image then it's a different story but I'm afraid in the end you won't be happy with the result.
