The optics Skywatcher N 150/750:

This versatile Newtonian reflector telescope offers the beginner to the advanced observer as much light and high stability for little money. It collects with its stately diameter of 150mm so much light that distant deep sky objects like the Ring Nebula in Lyra and the Dumbbell Nebula are nicely visible, globular star clusters like M13 can be resolved into many individual stars at the edge. Also, the planetary observation provides detailed images of Saturn, Jupiter, Venus and Mars. The optics has a focal ratio of f / 5 Thus, this telescope in the class of fast Newtonian telescopes. Photographically this look is particularly well suited. The light gathering power is about 450-greater than with the naked eye at 7mm exit pupil.

The advantages at a glance:

• Relatively high light intensity thanks to 150mm aperture
• Vibration and blowing up due to compact design
• Diffraction-limited parabolic primary mirror
• High-contrast imaging through thin spider vanes
• Built quickly and easily transportable
• Due to the short focal length can be kept short for astrophotography exposure times

The Explorer in the PDS version will ship with a dual speed focuser. This provides a 1:10 ratio for delicate focussing, which is essential especially for astrophotography, but also brings great advantages for visual observation. To further optimize the system for astrophotography, the barrel length was compared to the P Explorer version shortens slightly enlarged and the secondary mirror in return.

The mount NEQ-3:

This mount is a development of the EQ-3 in white finish. It provides a solid basis for most medium-sized optics and is very suitable for walks the night sky. If you have previously targeted the equatorial mount at Polaris, you can easily target an object, and adjust it with the flexible shafts. Fine adjustments are possible in right ascension and declination. The latitude of the place where you can fine a line scale and well secured with two bolts. Both Polar and electric tracking motors can be retrofitted with a control for both axes: the NEQ-3 is not only for visual observation, but also suitable for beginners in astrophotography. With optional extensions such as the motor set or GoTo upgrade kit long exposures are possible. With a little practice to succeed images of nebulae and galaxies objects.

Delivery of the mount:

• Mount with knobs for manual adjustment
• additional stabilizing spreader with Okularablage
• coordinated counterweights
