He BRESSER Messier Newton telescope has emerged, in recent years, as a work tool, also for astronomical photography, reliable and effective. With the new Messier NT-203s/800 with Hexafoc We can introduce you to the new generation of devices. The photo Newtons with parabolic primary mirror allow you to take deeper snapshots with the same exposure time thanks to its fast 203mm (8") f/3.9 aperture ratio. The large 85mm secondary mirror provides you with optimal field illumination. He Hexafoc 2.5" focuser High quality gives you a photograph without vignetting and without problems. The pipe clamps with 44mm universal dovetail rail. and carrying handle offer you the opportunity to mount a photographic device for a photographic camera. The Hexafoc focuser can be easily expanded later with a 10:1 gear ratio (Art.Nr. 0625720). For fine reproduction of stellar images you can optionally use the HR-Coma concealer (Art.Nr. 0510330). It is specially designed for use in the photographic and visual field, significantly optimizing the image, especially the contours of the field of view.

The BRESSER EXOS 2 is a mount with high load capacity and precise tracking for visual observations and astrophotography . He double radial ball bearing on both axles They ensure a precise and easy course. The right ascension axis bearing was optimized for less clearance. The tripod mount was reinforced to better absorb vibrations. In addition, the EXOS 2 is precisely crafted. Optionally, you can equip the device with a two-axis motor control (BRESSER Exos Duo) or a GoTo kit. This way you will keep celestial objects in the field of view or get your next target in the eyepiece with the push of a button. You can enter the world of astrophotography at a good price with the EXOS 2 without problems. The BRESSER EXOS 2 can load, depending on its length and purpose of use, up to 13 kg . of heavy optics, such as refractors with an aperture of 152 mm or reflecting telescopes with a short focal length of apertures up to 203 mm.
