More about the series Photon...
With its very fast aperture ratio, the N 305/1220 optics are ideal for astrophotography. The focus position and the large secondary mirror ensure a 100% illuminated image field of 22 millimetres – ideal for DSLR cameras in APS-C format and the use of an optional coma corrector.
With the extension tube included in the scope of delivery and the large aperture, this Newtonian telescope can also be used very well for purely visual observation of faint objects: This Newtonian is a universal instrument!
The fast aperture ratio is not only beneficial for photography, but the tube is also unusually short for a twelve-inch telescope. This has a positive effect on stability on the mount and makes transport easier.
The primary mirror can be cooled by a fan before observation. This allows for faster temperature equalisation, so you can start observing or photographing immediately after setting up and aligning the telescope.
Of course, the high-quality parabolic primary mirror is mounted in an adjustable position. This also applies to the secondary mirror, which is mounted in an adjustable position in a stainless steel spider that is only 0.5 millimetres thick. A vapour-deposited layer of quartz protects the mirrors while ensuring high transmission through the protective layer.
The telescope is equipped with a Monorail focuser: This focuser is a further development of the proven Crayford focuser:
- Instead of small ball bearings, a solid stainless steel rail is used, which is fixed on the side
- more precise guidance of the inner tube and no more tilting when clamping
Of course, the Monorail focuser also has a reduction gear, which is particularly important for astrophotography. A motor can be retrofitted.
