Dark Nebulae LDN 1608 & 1609

---

Using photographs from the National Geographic-Palomar Observatory Sky Atlas in both red and blue, Lynds identified 1802 dark nebulae in the declination range +90° to -33°. This photograph by my Celestron Origin was centred on the star HD 260530 in the constellation Monoceros (see photo). Two dark nebulae and an open cluster are in the field of view: LDN 1608, LDN 1609 and NGC 2259.
