20180908 Ghosts around Gamma Cassiopeia


My first try at this: I was afraid of not capturing anything as I had read it's a difficult and faint subject, but it shows ! (not everything though, but that's a hopefully good start)
Now the nebulas are small in the 130PDS field, but the whole scene is interesting.

Good sky seeing and transparency helped keep Gamma Cassiopeia ("Navi") glare far from the interesting nebulosity.

Disclaimer: elongated stars and lack of fine nebula details due to erroneous Polar Alignment.

Gear: Olympus E-PL6 with Skywatcher 130PDS 632mm/4.86 and SWCC at F/4.55 on Omegon EQ-300 tracking RA
Capture: 72 lights × 40s × 3200 ISO, master dark
Site: deep country 26km from Limoges, France
Sky: good (given bortle class 3, usual sqm 21.4)
Processing: DcRaw, Regim 3.4, Fotoxx 12.01+
