This is a two panel mosaic where I used one of the panels from my recent mosaic, containing Barnard 14 (with IC2087), and added a new panel (the bottom half of the image) dominated by Barnard 18. These nebulae belong to the Taurus Molecular Cloud. 12 hours of total integration time with the RASA 8 at f/2 brought out quite a lot of light and colour even in dark nebulosity.

From Wikipedia: The Taurus Molecular Cloud is a molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars. The Taurus Molecular Cloud is only 140 pc (430 ly) away from earth, making it the nearest large star formation region. It also reveals characteristics that make it ideal for detailed physical studies. It has been important in star formation studies at all wavelengths.
