What is the main advantage of the Regal M2 80ED's ED glass?
The Extra-Low Dispersion (ED) glass in the 80mm objective lens corrects for chromatic aberration. This prevents false color fringing (purple halos) around high-contrast objects, resulting in sharper images with more accurate, true-to-life colors compared to standard achromatic lenses.
How do I attach my DSLR camera to the Regal M2 80ED?
The Regal M2 includes a T-adapter ring. To attach your camera, you will need a separate T-ring specific to your camera's brand (e.g., Canon, Nikon, Sony). You unscrew the eyecup from the zoom eyepiece, attach the included T-adapter to the eyepiece threads, and then thread your T-ring onto the T-adapter. This setup allows you to mount your camera body directly to the scope.
Is the Regal M2 80ED suitable for astronomical viewing?
Yes, it's excellent for casual astronomical observing. The 80mm ED lens provides crisp, high-contrast views of the Moon's craters, the phases of Venus, the rings of Saturn, and the four largest moons of Jupiter. Its limiting stellar magnitude of 12.02 under ideal conditions also allows it to resolve brighter star clusters and nebulae.
What is the benefit of the 20mm eye relief on the Regal M2 spotting scope?
The generous 20mm eye relief at 20x magnification allows users who wear eyeglasses to see the entire 2.1° field of view comfortably without having to press their face against the eyepiece. This reduces eye strain and makes for a more pleasant observing experience, especially during long sessions.
How does the dual-speed focuser work on the Regal M2 80ED?
The dual-speed focuser has two knobs. The larger knob provides coarse focus, allowing you to quickly bring a distant object into approximate focus. The smaller, outer knob provides fine focus with a higher gear ratio, allowing you to make very small, precise adjustments for perfectly sharp images, which is especially critical at the higher 60x magnification.
For birdwatching, what can I expect to see with the Regal M2 80ED at 1000 yards?
At 1000 yards, the Regal M2 80ED offers a linear field of view from 110 feet wide at 20x down to 52 feet at 60x. At 20x, you can easily scan a shoreline or field to locate flocks of birds. Zooming in to 60x, you can resolve fine details like feather patterns, beak markings, and eye-rings on an individual bird within that group.
