This telescope is a true all-rounder and ranks among the best in this range. Thanks to the versatile focal ratio of f\/5, the Newtonian offers the best conditions for lunar and planetary observations. The optimized secondary mirror is designed for deep-sky observations and astrophotography. The advantages of the PHOTON Newtonian at a glance: • Moderate focal ratio for short exposure times for astrophotography. • Very high sharpness on the moon and planets • The secondary mirror provides good illumination, for example for DSLR cameras • The large backfocus allows the use of coma correctors and the most popular cameras • The high-quality primary mirror made of BK7 optical glass with a 94% enhanced reflectance coating provides a clear and bright image. • Stable 2\" Crayford focuser with 10:1 dual speed and 1.25\" reduction adapter • Motorized focusing can be installed at any time • Faster cooling, faster observations, faster photography thanks to the primary mirror fan • Steel tube and metal mirror cells for optimal adjustment stability • Available only from TS: carbon tube for subsequent installation - for optimal transport. Why do we recommend a PHOTON Newtonian instead of all other similar Newtonians? This PHOTON Newtonian telescope is equipped with GSO optics. The manufacturer consistently maintains high optical performance for the mirrors. Furthermore, a PHOTON Newtonian telescope can grow with your needs: • For the 8\" Photon Newtonian, we offer a carbon tube upgrade kit that allows you to reuse all components of the Newtonian, except for the tube. • We offer secondary mirrors of different sizes, so you can adapt the Newtonian to your individual needs, whether for planetary observation or deep-sky imaging with a full-frame sensor. The precise 2\" Crayford focuser with 1:10 micro-drive: We offer this Newtonian telescope with a 2\" Crayford-style focuser with integrated 1:10 dual-speed drive. This focuser works very precisely even with heavy accessories such as astro-cameras. With a bit of experience, you can achieve precision around 0.08 mm, which is sufficient even for ultra-high-resolution sensors. The focuser is fully compatible with the optional TS Motorfocus system, which allows for precise, vibration-free focusing for visual observation or astro-imaging. Quick manual for the focuser: Telescope-Service provides a quick guide for TS Crayford focusers. You can download the PDF here. High-quality primary mirror with f\/5 and 94% reflectivity: This Newtonian shows its full potential in observation and astrophotography thanks to a high-quality primary mirror made of BK7 optical glass, free of internal stress. The parabolic mirror has a coating with 94% reflectivity, thus offering a brighter and higher-contrast image. You will immediately notice the difference compared to a standard coating. Thanks to the f\/5 focal ratio, this Newtonian is one of the all-around telescopes for astrophotography and observation. No vignetting at the edges - full illumination thanks to the large 63 mm secondary mirror: No shadows at the edges, you will be satisfied with a bright image with full illumination even with modern DSLR or CCD cameras. But even 2\" wide-field eyepieces are supplied with light right up to the edge of the field stop. Enjoy your images more with optimal field correction - Teleskop Service consultation service: Only a good coma corrector turns this Newtonian into a true astrograph. Our recommendation is the TSGPU corrector, ideal for this telescope. It ensures maximum sharpness across the entire field, so only the TSGPU (see accessory recommendations) makes this Newtonian a true astrograph. Astrophotography with DSLR cameras: • TSGPU Coma corrector • SKM48-... T-ring matched to the camera mount ... and you already get the optimal distance and sharp stars in the entire field of view. Guiding can be done via the finder or a small guide scope that fits into the finder shoe (or bracket).
