This is my Rosette. I shot it last night. 42 - 300 sec subs, 20 dark, 20 flat, 20 bias. Shot with William's optics star 71 astrograph, ioptron ieq30 pro mount, asi294mc pro camera (guided), with an optolong l-enhance dual narrowband filter. Processed by extracting the two channels then combining to make a synthetic green channel. Thanks for looking.....
