He BRESSER Messier Newton telescope has emerged in recent years as a reliable and effective work tool, also for astronomical photography. With the new Messier NT-203s/800 with Hexafoc We can introduce you to the new generation of these devices. The photonewtons with parabolic primary mirror allow you to take deeper snapshots with the same exposure time thanks to their fast 203mm aperture index (8") f/3.9. The great 85mm secondary mirror provides you with optimal field illumination. The high-quality Hexafoc 2.5" focuser gives you photography without vignetting and without problems, the pipe clamps with 44mm universal dovetail rail. and carrying handle with the option of mounting a photographic device for a camera round out this great package. The focuser can be easily expanded later with a 10:1 reduction ratio (Art. No.: 0625720). For fine reproduction of star images you can optionally use the HR-Coma corrector (Art. No.: 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.

Please keep in mind that Newton-type reflecting telescopes are especially suitable for the night sky, but they do not give such good results for landscape and nature observations during the day. For landscape and nature observations we recommend a refracting telescope from BRESSER.
