Review on SVBONY SV129 Extension Length M42X0 75 by Ben Alvarez

Revainrating 5 out of 5

M42/T2 extensions are useful

If you are fully committed to astronomy then the T2/M42 extension kit will come in very handy. The Svbony brand is well made and very affordable compared to others. Since it's just an extension, there's not much need for premium brand names as long as the thread specs match. These extensions easily fit T2 and M42x0.75 threads and are quite well made.

Pros
  • male and female threads are M48*0.75mm; Fixing distance problems in astrophotography and fixing a number of focusing problems
Cons
  • not reliable
