Due to changes at the machine shop with my cousin's retirement, I will be selling off existing stock, but not replacing it. If you want something, get it now before it is gone.

Dovetail Bar
for Takahashi Telescopes

If you are using Takahashi clamshell rings, or an older Mewlon 250,* I think you will find this dovetail bar very useful. The offset mounting holes and extra length allow more DEC balancing capability without adding weights to the OTA. The dovetail part is the same as on Losmandy D (G-11) dovetail bars, and fit my DoveEM, DoveEM500, and standard dovetail saddles. The overall bar is only 3" wide because the extra width is not needed for the M-250 or Takahashi clamshell saddles. The bars are machined from 3/4" stock with all surfaces machined to remove surface blemishes and stresses (thus preventing warpage). The final thickness is 0.650 in.

If you are using a newer Mewlon 250,* Mewlon 300, TOA-150 or BRC 250, see the LgTalPlate page.

14" EM Dovetail Bar

For EM Clamshell Rings, or older Mewlon 250*

*This dovetail bar was designed to bolt directly onto the original Mewlon 250 with four stainless steel M6 socket head cap screws (we provide screws). The hole pattern is 48mm x 82mm. Check the hole pattern on your M-250. Some versions of the M-250 require my LgTakPlate.

This dovetail bar may fit other Takahashi OTAs. .

Or, it can be used with one or two Takahashi clamshell rings. Two rings will provide a more rigid setup for imaging with larger refractors (two sets of M8 screws provided). The centered mounting holes make it possible to use a single clamshell ring on an NJP mount equipped with my new 14" DoveNJP saddle.
