Takahashi Collimation Scope??

[HCR32]

Does anyone know if the Takahashi Collimation scope works on a Mak Cass?

If the aluminised secondary on the meniscus is spotted then yes but there is no way to adjust the secondary, only the primary mirror. I think it would be overkill and an unnecessary expense. Have a look at how Orion recommends to do it. http://www.ioptron.com/v/Manuals/6101_MAK150_Collimation.pdf
