I used an ASI1600 MM-Pro & 8 position EFW with ZWO LRGB and Baader Ha filters, coupled to a Samyang 135mm F2 DSLR Lens. @ F2. All frames used gain 76 offset 20
My mount is a Skywatcher EQ6-R and ZWO 290MM Mini / ZWO 30mmF4 guiding combination.
Capture software Sequence Generator Pro, Ha frames guided with PHD2, integration and mosaic creation in AstroPixel Processor. Final touches & saturation boost in Photoshop.
