The Photoline corrector is optimized for the TS 85 mm f/6 APO and ED refractor telescopes and corrects the field of view for astrophotography up to full frame format.

• Shortening factor 0.92x
• Connection telescope side: M63x1 male thread
• Connection camera side: M48x0.75 male thread
• Working distance: 55 mm from the connection thread
• ED design for good correction on axis and in the field
• The corrector is optimized for all refractors with 85 mm aperture and f/6, but it will also give good results with similar telescopes.

The corrector is optimized for the TS 96 mm f/6 APO and ED refractor telescopes and corrects the field of view for astrophotography up to full frame format.

• Shortening factor 0.92x
• Connection telescope side: M63x1 male thread and M70x1 male thread
• Connection camera side: M48x0.75 male thread
• Working distance: 55 mm from the connection thread
• ED design for good correction on axis and in the field
• The corrector is optimized for all refractors with 96 mm aperture and f/6, but it will also give good results with similar telescopes.

Flattener and field corrector for compact 70 mm and 72 mm APO refractors for astrophotography and countryside photography.

• Designed for APO and ED refractor telescopes with 70-72 mm aperture for optimal and sharp astro images.
• Connection at telescope side by M63x1 male thread (with rotation) - M54x0,75 and M68x1 male thread (wihout rotation)
• Connection at camera side by M48x0.75 photo thread
• Working distance from the M48 thread of 55 mm - you have automatically the correct distance if using a DSLR camera and the matching T-adapter.
