Description

Here I aimed my dual-RASA rig at an area south-east of Sh2-140 that looked quite interesting on Aladin Sky Atlas but still seems to be very rarely imaged. It contains many interesting features including long red filaments. Could they be bow shocks of a supernova remnant? Since the spectral widths of the NBZ dual-band filter is rather broad I am not sure which of the blue areas are Oiii or blue reflection nebulosity.
