🔭 Recommended Telescope & Astrophotography Gear for 161P/Hartley-IRAS
To capture the extended dust and ion tails of a comet, wide-field astronomy binoculars (10×50 or 15×70), fast ED apochromatic refractors (70–100mm f/5), or smart telescopes (ZWO Seestar S50) paired with cooled CMOS cameras deliver the best signal-to-noise ratio.
