LBN 552 is an object listed in the Lynds’ Catalogue of Bright Nebulae. This catalogue, compiled by Beverly T. Lynds, lists various bright nebulae observed throughout the night sky.
LBN 552 is an extensive molecular cloud complex. It is very faint and located in the constellation Cepheus, about 600 light-years from earth. It is known for being one of the dimmest objects in the Lynds Bright Nebula catalog. It is often imaged together with the dark nebula LDN 1228. The pair are sometimes informally called the “Fighting Dragons“. It’s essentially a cloud of dust reflecting the light of nearby stars.
LBN 552 is classified as a “bright” nebula in the Lynds catalog. However, in practice, it is very faint. It is challenging to observe or image due to its diffuse nature. It contains a mixture of diffuse dark and light nebulosity. Most images of this cloud complex I’ve seen were bought from a service. Others were imaged from a remote hosting site. Very few taken from a backyard with a personal telescope.
This image is a touch over 11 hrs of exposure acquired from my driveway using APT running on a NUC. Esprit 120ED telescope f/7 at 640mm paired with the ASI 2600MC camera atop a Skywatcher Eq6r Pro mount. Processed manually using PixInsight. All of the acquisition detail here in the astrobin version.
