This is a 2x compact Barlow lens which is combined with a 1.25" T-adapter for DSLR cameras.

This device can be used either as a 2x Barlow; or as a 2x Barlow and a 1.25" T-adapter for the connection of DSLR cameras to telescopes (with a necessary DSLR T-ring, also known as T2 mount); or just as a T-adapter without the compact Barlow lens.

Sometimes when a DSLR camera is connected to a telescope with the camera lens being removed, the image cannot be focused on the camera's viewfinder. This is because the image focus point is shifted beyond the focus adjustment range of the telescope. This T-adapter with a compact lens enables the cameras to get a focused image through a wide range of telescopes.
 

Description:

  • This is a new design to combine a compact 2x Barlow lens with a 1.25" T-adapter which has got standard M42x0.75mm exteral thread for the connection of DSLR camera T-rings (T2 mount).
     
  • The 1.25" T-adapter tube can be inserted into telescope's eyepiece holders (focusers) with standard 1.25" (31.75mm) diameter. You can then either put a 1.25" eyepiece into this T-adapter barrel to get a 2x magnification, or connect a DSLR camera to this T-adapter (through a relevant T-ring, also known as T2 mount).

    Note: The camera T-ring is not included in this listing, but it is available from this store.
     
  • The compact 2x Barlow lens can be detached from the T-adapter tube and then attached to an eyepiece barrel with M30x1mm internal threads.

    Note: There can be different inner threads within eyepiece tubes, such as M30x1mm, M30x0.75mm, or M28.5x0.75mm. This compact Barlow lens can fit M30x1mm internal threads of eyepiece barrels.
     
  • The device enables a perfect alignment between the central axis of the eyepiece and the Barlow lens.
     
  • The lens is built with quality optical glass Bak-4 and with multiple broadband anti-reflection green coatings to reduce light reflection and to limit the effect of chromatic aberration.
     
  • Full metal construction.
     
  • Comes with two caps for both ends and an eyepiece fixing screw.
     
  • Dimensions:
    • overall length: 44mm;
    • The depth of 1.25" barrel for holding eyepieces: 25mm
    • The length of 1.25" tube (including the compact Barlow) for inserting into telescope's focuser: 17mm
