150 mm aperture, combined with the superb parabolic optics, provide a bright and, due to the pure mirror optics, chromatic aberration-free image.
The small focal ratio of 1:8 together with the 1.25" focuser allows the use of a compact secondary mirror and the use of simple but very good eyepieces. This allows particularly enjoyable planetary observations. Up to about 240x magnification can be easily achieved without having to worry about blurring caused by the optics, above 300x the unavoidable diffraction disturbs the image. This telescope surpasses the performance of a similarly sized achromat and comes close to an apochromat, at a fraction of the price!
The Newtonian can also be used for astrophotography to a limited extent - with APS-C, vignetting is only to be expected in the outermost corners.
♦ Powerful, diffraction limited parabolic mirror
♦ Adjustment stable due to robust metal cells for primary and secondary mirror
♦ High-contrast imaging due to small secondary mirror and thin spider vane struts
♦ Practical 6x30 viewfinder for easy finding of objects
♦ 1.25" rack and pinion focuser made of metal, low tilt and reliable
♦ Direct camera connection for parallel photography to the telescope (star field photography)
♦ Moderate speed (f/8) - simple eyepieces of high quality can be used, e.g. Orthos
♦ Versatile instrument for observations at medium and high magnification
♦ Uncomplicated adjustment, therefore recommended for beginners
This equatorial mount from Skywatcher is very well suited for mobile use, but also a solid base for astrophotography. With suitable drives you can successfully take pictures of the moon, planets, nebulae and galaxies. For visual use, manual fine adjustment using the supplied flexible shafts is sufficient.
