Description

Besser als erwartet: eigentlich nur ein Nebenprodukt zur M 31 desselben Abends. Das Gesichtsfeld hinter unserem Haus ist sehr begrenzt, und für Objekte mit einer Deklination wie M 42 gibt es nur eine schmale Lücke zwischen einer Wand und einem hohen Baumbewuchs. Als M 31 im Kasten war, lag M 42 genau richtig. Die Lücke reichte nur für 15 Lightframes, von denen dreizehn brauchbar waren.

Better than expected: basically a side product to my recent M 31 at the same night. The field of view on my garden site is very limited, and there is only a narrow gap between a wall and some trees for objects with a declination like M 42. When the session on M 31 was finished, I found M 42 at the right place to obtain just 15 lightframes, from which 13 looked usable . For version B, I applicated a blurred mask and tried to smoothen the background a little bit more.
