First light on my (new to me) ZenithStar 73, and indeed my first glass with any astrophotography chops! Have been working with vintage SMC Takumars to date. Great way of getting into the hobby without remortgaging, but wow what a leap forward an actual refractor provides. Stack of 30*90 second subs at ISO 1600, calibrated with dark, flat and bias frames. Stacked in DSS, cropped & processed using Graxpert, Photoshop & StarNet Gear: William Optics ZenithStar 73 + 73R Flattener/0.8*Reducer Unmodded Canon 6D with a Svbony CLS filter.
