    The larger aperture of the SkyWatcher ED120 Telescope provides you a dramatic increase in resolution and observe the lunar and planetary surface phenomenon in 3D-alike high-definition. The tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pin points, star upon thousands of stars deep into the objects core.

    For Deep-sky observation, rich aggregates of stars within Galaxies, Nebulas, and open clusters appear brilliant contrasted against a very dark velvet black background. The wispy, delicate, feather-like structure of dust lanes and extension of glowing gasses can be seen reaching out far beyond the object’s core.

    Overall Score
    Back in the 1970s I was interested in solar observations and spectroscopy with little experience of in stellar observing.
    Now I have this fine telescope, I'm looking forward to astronomical photography and understand DeepSkyStacker principles.
