Model-specific optical spacing
The current manufacturer table gives two separate spacing references for APO160FL f/7: “Back Focus Range” is 124 mm, while “Back Focus Real” is 115 mm. These are different mechanical references, so use the drawing and adapter that match the imaging train.
Focuser connection
The FRC fits the Starlight Instruments FTF3545 focuser. With the named APO160FL f/7, applying the 0.9× factor gives a calculated 1008 mm focal length at approximately f/6.3. TEC supplies the reducer configuration for the telescope specified when ordering.
