Il s'agit d'un réducteur standard doté également de capacités d'aplatissement de champ. Un rapport focal plus court permet à l'OTA d'avoir un champ de vision plus large et des temps d'exposition plus rapides, ce qui le rend adapté à la capture de vastes zones de nébuleuses, d'amas d'étoiles et d'objets célestes faibles et se déplaçant rapidement.\u003c\/p\u003e\n\n\u003cp\u003e Le réducteur 0,8x adopte une conception triplet et prend en charge un cercle d'image plein format de 44 mm. Le poids total est de 0,48 kg. La mise au point arrière du filetage M48 est un 55 mm standard. Le filetage avant est M84*1. Côté caméra, il est équipé d'adaptateurs M54*0.75 et M48*0.75 de deux tailles, pratiques pour la connexion. En même temps, il dispose d'un filetage de filtre M48 * 0,75 2 pouces intégré, qui peut être directement installé et utilisé. Les capuchons métalliques filetés aux deux extrémités usinés CNC empêchent les cendres lorsqu'ils ne sont pas utilisés.\u003c\/p\u003e\n\n\u003ch3\u003e Spécifications techniques
