Add to wish list
The M48 variable adapter is designed to help you fine tune the distance between your DSLR or CCD camera and your field flattener/coma corrector, for optimal results. The M48 thread used on this system is the same M48 thread used on standard 2" eyepiece filters. This is a very versatile system and many combinations are possible.
3x items are provided in this kit:
- 5mm M48 female to male spacer
- 10mm M48 female to male spacer
- M48 variable locking ring
You can screw the M48 variable adapter into either of the two M48 spacing rings provided.
Then you can fine-tune the remaining distance by twisting the locking ring on the M48 variable adapter and tightening the spacers up to the desired point. 
  • With this kit, you can achieve spacing from 17 to 29mm by using the two spacers provided.
  • Using the M48 variable locking ring, with 5mm M48 extension ring, you get spacing from 17-19mm.
  • Using the M48 variable locking ring, with 10mm M48 extension ring, you get spacing from 20-24mm.
  • Stacking the 5mm +10mm spacers and variable locking ring, you get spacing from 25-29mm.
  • The 5mm and 10mm M48 spacers can also be used on their own without the variable adapter part, or they can be stacked to provide total spacing of 15mm (5mm +10mm = 15mm).
You can also buy other M48 spacers and extensions separately, and use them with the M48 variable locking ring, for example:
  • Using the M48 variable adapter, with 20mm M48 extension ring, you get from 30-33.5mm spacing
  • Using the M48 variable adapter, with 30mm M48 extension ring, you get from 40-43.5mm spacing
