Description
For photography of nebula or star clusters
This reducer is designed to shorten the effective focal length. This allows shorter exposure times and a wider field of view for astrophotographers. Since you can obtain a wide field of view, it becomes easier to capture nebulae and star clusters that have spread.
Reduce the focal length (0.67x) and make F-ratio fast. It also has the effect of reducing the aberration near the edge of imaging field.
