Swan Nebula in Hubble palette

Recommended Posts

SPX350 F4.5, ST10XME, Astrodon filters SII5nm Ha5nm OIII3nm

The Swan is a very bright nebula with fantastic dynamic range full of SII, this Hubble rendition uses Ha and SII blend as luminance. My new ST10 is sensationally sensitive in narrowband with a well depth that extracts the faintest material nicely.

Ha+SII-12x10min subs

OIII-18x5min subs.

Thanks, John.
