LBN 603 is a vast region of dark nebulas in Cassiopea. The dusty structures extend on a dense starfield forming several cotton-like shapes.

The dark nebulosity is very faint and it required 11hr integration of L filter and a special post-processing technique to highlight the finer details. 3hrs of R/G/B each complete the integration.
