This is my first kind of complete mono image taken with my Tak E130D and new SX694 camera plus Astrodon 3nm filter. I should really do a side by side with my other (Baader F/2) Ha filter and possibly test out a 5nm Astrodon to make sure I'm not losing too much light with centre-wavelength shift at F3.3.  Image comprises 20x1800s subs, processing was fairly gentle in PI; could do with (even) more data to make it easier for me to bring out the finer/fainter details a bit more. Also hoping to add OIII at some stage.
