Captured M42 Orion Nebula last week over 3 nights during the New Moon period under my B8 City suburban skies. Its been just over 2 years since I last imaged this spectacular celestial object. I chose Narrowband in lieu of Broadband to see how the 2600MM and Antlia 3nm filters performed with shortish Narrowband subs.
