Aperture ring for 10" Skywatcher tubes
The aperture ring is inserted into the tube and improves the contrast of the image. With a free aperture of 254 mm, it should not be too far away from the primary mirror, otherwise it will cause vignetting. Positioning it about 100-150 mm away from the primary mirror surface produces a good result.| Outer diameter: | 284 mm |
| Free aperture: | 254 mm |
| Length: | 51 mm |
| Material: | plastic |
