Model: Apo 180/1260 CNC-LW II
It will have 5 mm more aperture and a shorter FL, the result being better transportability and faster imaging speed with a wider field. The color correction and optical quality will not differ visibly from the 175 f/8. It will offer you detail on the planets you may have never seen before. It's an excellent CCD imaging machine as well. The newly designed, lighter CNC tube permits usage of this large Apo on transportable, medium sized mounts.

The tube rings are flat on both sides and offer five tapped 1/4-20" holes perpendicular to the tube line with one centered. The middle two hole's center to center spacing is 60 mm (2.362") and outer two hole's spacing is 3.2" (Astro-Physics standard)
