Carbon Fiber Tube Design
Minimizes thermal expansion which causes focus shift as temperature changes during an imaging session. Carbon fiber also reaches ambient temperatures quickly and is extremely lightweight and rigid to help ensure excellent imaging data is produced.
Dovetail Expansion Joint
Allows for the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminum dovetail to expand and contract without stressing the carbon fiber lower truss. This results in images that are not distorted due to expansion, or contraction of the optical tube materials.
2.75-Inch Hedrick Focuser
Heavy-duty no-slip focuser with 1.3" of drawtube travel when fully racked out. The focus tube runs on 5 bearings and is driven by a leadscrew, so there is no chance of slipping. Focusing is automated through PlaneWave Interface 3 (PWI3) software when using the sold separately PlaneWave Electronic Focuser Accessory. PWI3 performs fast and extremely accurate autofocusing routines to ensure your images are always at critical focus.
Three fans blow out of the optical tube pulling air through the telescope and by the primary mirror. This helps the telescope to reach thermal equilibrium quickly. The fans are controlled by a switch on the optical tube, or can be controlled by via PWI3 software if a PlaneWave Electronic Focus Accessory (EFA Kit) is purchased.
