I saw some great pictures of Sh2-88 before which have been taken using an H-alpha filter. Since I am not yet having an H-alpha filter I just decided to give it a try without H-alpha. Of course the nebula structures don’t come out as good as when using a such a filter. But I am still satisfied for a picture with just 5 IR frames. The seeing with my f/5 GSO Newton (F=1000mm) was around 2.1″ – so quite good for this region.
