Lunt 60 with 2.5x or 3x Powermate?

[keramos]

Folks,

I'm looking to purchase a 2.5x powermate for use with the Lunt60 (I'm already using 2x Barlow).

Was wondering, would 3x powermate be pushing it or should I stick with 2.5x powermate?

Any suggestions....

I'm not aware there is a 3x powermate unless you stack a 1.5 and 2x (the latter is 2" anyway).  I use a 2.5x powermate with my Lunt 60 because it suits my setup with pixel size of the ASI 174MM and of course it is a 1.25" so fits the 1.25" blocking B1200 diagonal.

Hi Chris,

Yup its actually a 3x Barlow (Tele Vue), and since it was listed next to the powermate (and looks so similar) I completely missed the description.

I use a x2 Barlow also a x2.5 Powermate, the Barlow gives a bigger image scale. Occasionally I use them both together, but this really is pushing the Lunt50mm/seeing to far most of the time.
