Shapstar hyperbolic astrographer 130 mm - f/2.8

With the hypergraph 130, Sharpstar has created a telescope for mobile astrophotography. With a tube length of less than 40 centimeters, the "small" hypergraph slips even in aerial luggage.
On the sky, however, the performance is remarkable. The Fast Focal Focal Report of F/2.8 allows you to properly expose an object in a single night, or even to focus on several objects.

The 2-element corrector offers a very good field correction with complete lighting beyond the APS-C format. With a flat, you can even use full -format cameras.

The 55 mm working distance of the M48 thread on the carriage carrier allows easy adaptation of all common astro cameras, digital reflex and system cameras.

The advantages and characteristics of Sharpstar hypergraphs at a glance:

• Optics optimized for astrophotography with high resolution throughout the usable image field.
• Carbon tube for much better stability of focus than a metal tube. No need to readjust the focus when the temperature changes. The images are clearer.
• The secondary mirror is integrated with the offset (offset) required, the image field lighting is more uniform.
• Despite the extreme focal ratio, the telescope is collimative and it maintains collimation during transport.
• The eye door has been further improved and now allows an even better development. It perfectly maintains the focusing position, even over a long period of time.
• The double -speed focus is already integrated, which is also necessary with the extreme focal ratio of F/2.8.
• Transport handle with mounting surface for search shoe
• Easy adaptation of the camera via the M48X0.75 connecting thread of the carriage carrier. The working distance is 55 mm.

Simple adaptation of the camera via the screw of the carriage carrier

With such a resolution and rapid optics, a screwed adaptation of the camera is necessary. This prevents the inclination and therefore the stars blurred on the edge.

The R & P 2.5 "R & P 2,5" M48X0.75 rowing holder in addition to the M63X0.75 female thread. The working distance of this thread is exactly 55 mm. This corresponds, for example, exactly the distance required by A SLR camera and the corresponding TA adapter. The Astro cameras, such as those of Zwo, are also already provided with an adapter kit for M48, which exactly takes this distance into account.
