CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
btw, can you try a version without the use of the LPR for comparison? Might suspect the LPR is introducing unneccessary multi-order gradients, but better to make sure. Hope you could do this if you have time and weather permits. Interesting results nevertheless!
hi...
just wondering, by taking a plain white background image through the LPR filter, and calibrating some photo software, it is possible to reverse the effects of the colour shifts?
I was bored and I played with the image a bit. I created 'pseudo-flat' by applying excessive median filter and gaussian blur to wx's original image, then i blended the 'pseudo-flat' with the original.
no more green but alas, lost some reddish nebulosity data as well. :roll:
