Description

I already have the debayered Nikon d5100 for almost a year, but so far there was no opportunity to do some narrow band imaging with it. This is also first light for my newly acquired Skywatcher Esprit 100 refractor. This Ha data was taken around full moon (+- 3days). Weather permitting, i will add OIII data at a later stage.
Rev. B: Ha data with reduced core brightness.
Rev. C: OIII data. I would like to stretch the image more, but the noise starts to dominate. I hope i can gather more data. The running man is much better visible with this filter.
Rev. D: Bicolor Version. There`s alot to experiment when doing the channel combination.
