- The ‘open’ arrangement allows for quicker temperature equilibrium of the mirrors for the best performance.
- The CNC machined locking points and truss arrangement ensure a strong, rigid constructions that will hold collimation effectively.

Solar Warning:
Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result. Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
