Description

Here are a pure Ha version of my recent post. Messed up a bit with framing (camera rotation) last night. Can only blame the cold (-16°C) and my stiff fingers. So the framing is different from the HaRGB version, but it reveals a bit more details. It is collected both with the Esprit 100 with ASI1600MM (Baader 3.5nm Ha filter) and the Esprit 150 with ASI071MC (Baader 7nm Ha filter). 64 subs and a mix of 10 and 20 min exposures.
