Filter Gets H-Alpha Across Milky Way
Have used a similar filter in the past with a Canon but here we have the D800. I was worried but with a lot of expert help I flashed the firmware of the D800 to deal with sensor gradient issues that affect flats. I extracted the R channel from the debayerized images in PixInsight and stacked them. Work is still in progress but generally looks great. Am using with the Nikon F1.4 50mm lens stepped back to 2.8 to deal with star anomalies. I plan to do most of the Milky Way. People can contact me as jerryyyyy on Astrobin if they want to see the images... current a work in progress... but a lot of details.
