Hyperbolic flat-field astrograph from Sharpstar with 130 mm aperture and fast f/2.8 focal ratio

• Aperture 130 mm / focal length 364 mm / focal ratio f/2.8
• Optimally suited for mobile astrophotography with modern, high-resolution digital cameras
• Ideal for cameras up to APS-C and with Flat even up to full-frame sensors
• Hyperbolic primary mirror with 130 mm diameter
• 2-element corrector with one ED element
• Modern dual-speed 2.5" rack and pinion focuser
• Working distance from M48x0.75 camera thread is 55 mm - Working distance from M54x1 female thread is 57.2 mm
• 2" filter thread for connecting fog filters is included in the reduction adapter to M48
• Carbon tube for optimal hold of focus position - provides better focus stability than a metal tube
• Stable metal secondary mount with adjustment screws
• Primary mirror collimation with tension and compression screws
• Included in delivery are a carrying case, CNC tube rings and an EQ5-style dovetail bar
• Each Hypergraph is checked, cleaned and adjusted at APM.

Newtonian telescope with 6" aperture and 600 mm focal length individually made for you in Germany with high quality carbon tube - an ideal travel telescope and for astrophotography

• Aperture 150 mm / focal length 600 mm / focal ratio 1:4
• Three focus positions built in - simply by moving the main mirror, thus all correctors, also focal reducers, can be used
• Stable, 4 mm thick carbon tube for maximum rigidity and adjustment stability
• TS UNCN2-G2 ball bearing RAP focuser with screw possibility for photo adaptations - optimal for photography and observation - of course motorizable
• Valuable lightweight rings and tube end pieces - individually manufactured for this telescope.
• TS "Black" anti-reflective paint provides a dark tube and prevents annoying reflections
  Selected quality optics for best imaging
• 94% reflection on primary mirror and secondary mirror for a brighter, high contrast image
• Stable collimatable primary mirror mount, specially made for this telescope
• Each ONTC Newtonian is tested on the optical bench of Teleskop-Service before shipment - delivery with production protocol
• The tube rings and the end pieces are also manufactured in black on request.
