INCLUDED ACCESSORIES
| CDK24 Focus Spacer (240343) | This 5.3" long spacer may be installed between the backplate and the focuser to take up some of the CDK24's extra backfocus and reduce the torque placed on the focuser mechanism. This spacer is sized such that the backfocus distance behind the focuser will match that of the CDK20. |
| Ronchi Spacer (200354) | This spacer sits in place of a focuser and is used for setting the primary to secondary spacing. It has an 1-1/4 inner diameter and may be used with 1-1/4 oculars for collimation. |
| Ronchi Ocular | This ocular is a Ronchi screen used for setting the primary to secondary spacing. |
