Description

The spaghetti nebulal (Simeis 147) is and remains a very tough nut for me. At the end of December I used the opportunity to record the star field in RGB. There is no sign of the supernova remnant (Simeis 147). In my latitudes there is nothing without an H-alpha filter. I experimented for a long time how I can bring the two images together so that the nebula does not move too far into the background. In the end I decided to only use the colored stars from the RGB image.

Der Spaghettinebel (Simeis 147) ist und bleibt für mich eine sehr harte Nuss. Ende Dezember hatte ich noch mal die Gelegenheit genutzt, um das Sternenfeld in RGB aufzunehmen. Vom Supernovaüberest (Simeis 147) ist da nichts zu sehen. In meinen Breiten geht da ohne H-Alphafilter nichts. Ich habe lange experimentiert, wie ich die beiden Aufnahmen zusammenbringen kann, damit der Nebel nicht zu sehr in den Hintergrund rückt. Habe mich dann letzten Endes entschieden nur die farbigen Sterne aus der RGB-Aufnahme zu übernehmen.
