Description

I tried several things with the triangulum galaxy. Image A has been taken under a good sky without any filter, while the moon was at about 50 %. Version B was taken under very humid conditions with the Baader Neodymium under nearly the same moon. Version C is both combined. Postprocessing was done nearly similar. With the Neodymium attached i always have problem with the background extraction process, you can see it at the corners which remain reddish. Version A looks cleaner to me than Version C, although in the combined image some details are clearer. The Neodymium helps to bring out the Halpha-Regions.

My conclusion: The Neodymium works best when used on the moon and the planets, for deep sky it can help to bring up some features, but postprocessing is getting harder. Second conclusion: One can take easily DS-objects under a bright moon without any filters, but the image will be not as good as it could have been.
