Messier 46 and NGC 2438
From 04/24/2022 to 05/03/2022 I spent some time at the Tivoli astrofarm in Namibia. During that stay I took several deep images of the southern sky with the equipment of the observatory „Drebach South“, one of them was the open cluster Messier 46 with the planetary nebula NGC 2438 in the constellation Puppis.
