Review on M48X0.75 Extension Tube Kit For Astromania Astronomical 2 - 5Mm 8Mm 10Mm 20Mm 30Mm Lengths On Both Sides by Muhamed Hogan

Revainrating 5 out of 5

Extentions and T-Thread (48mm)

Use these T-Thread (48mm) 2" to extend back focus or ad length to 2" (48mm) tubes for astronomy. Work great.Do not tighten them too much and use just a hint of lubricant to keep them from binding or galling. Use quality strap wrench if you over tighten them with your fingers.

Pros
  • 10 x 1.2 x 5.3 inches
Cons
  • The kit may not be suitable for beginner users who are still learning how to use their telescope and its accessories
