I have wanted to image this target for a couple of years now and I chose to mount my WO FLT132 rather than my widefield FSQ85 to help get closer to the target. The Propeller sits within a much wider emission nebula complex in Cygnus and is often imaged with NB filters, regularly in the strong Ha signal and also in HST palette with the much fainter SII and OIII. The Propeller is also referred to as Simeis 57, and I have also read that this is its 'proper' catalogue designation and DWB 111 is incorrect.
Details: WO FLT132 at F5.6; QSI683 wsg-8; 10 Micron GM1000HPS; Astrodon 5nm Ha; Captured with SGP and Processed in PI; 15 x 1200s Ha giving 5 hrs total integration.
6 Panel mosaic comprising 108 x 1200s Ha 5nm subs.
