LBN 569 is a molecular cloud that is relatively low in brightness—it appears as the whitish gas portion in the image. It was discovered in 1965. The LBN catalog (Lynds Bright Nebulae) mainly lists this type of so-called “bright” nebulae, not to be confused with the LDN catalog (Lynds Dark Nebulae).
This area lies at the very top of the constellation Cepheus, not far from the North Star. It was a triple challenge : first, the proximity to the celestial north pole made it difficult for some mounts to track this part of the sky, leading to issues such as field rotation; and second, because the IFNs (Integrated Flux Nebulae) in this area are particularly faint.
