The evening of 24th June 2015 was a warm and nice summer evening. All the clouds vanished and the forecast predicted a clear night 🙂 Since I didn’t image a nebula for quite some time I decided to image one this night. Recently I came across Sh2-88 which is an HII emission nebula in constellation Vulpecula. So this should have been the target for tonight!
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.
