  • All models come with a 2″ Crayford-style 10:1 dual speed focuser, 2″ to 1.25″ adapter, and carry case.
  • Use as a nighttime telescope or add a front-mounted h-alpha filter package for solar use.




Optical Tube Assemblies

You can buy the Lunt ED Doublet optical tube assemblies in three apertures: 70 mm, 80 mm, and 102 mm. The unique thing about these OTA’s is they can be used for White Light, CaK, or nighttime use with the addition of the proper filters or accessories. We have used the Lunt Engineering logo on these scopes to differentiate them from dedicated H-alpha solar telescopes with the Lunt Solar Systems logo. Lunt Engineering is a division of Lunt Solar Systems. You can now buy one telescope for viewing both the Sun or the nighttime sky. This makes these telescopes versatile and cost effective. You never have to worry about safety with the proper Lunt attachment for viewing the Sun.

Included Accessories:
