Description

I recently posted an Ha image of the Dolphin Head on the technical forum showing some pretty extreme ghosting [see Rev B] from the bright star o 1 Can Maj in the frame.    Thanks to @GalacticRAVE for pointing me towards the post-processing solution, and to Telescopes Live for the Ha data used to correct, I was able to recover the the HA data and assemble a reasonable image.

It is reassuring to know that data is recoverable - if you have data from another source. But it is a bit of work with PixelMath.
