Bought a TMB 105/650 and wonder if it would be ok to use my 1.25" Lunt solar wedge?

I would call Lunt since you are on the edge of what they recommend (4" and under) for that wedge.  For 6" and under they recommend the 2" on their website.

Would be just fine, but unfortunately, nothing much to observe in white light these days :shrug:

 

Recommend this site to quickly check for any sunspots. You are in luck actually, there IS something to observe now :)

BTW, make sure you have your ND filters in place smile.gif

 

The wedge should have a ND filter installed but the image is still too bright. A polarizing filter threaded to the eyepiece will allow you to control the amount of light since the diagonal acts as the second part of the polarizing effect - just rotate the eyepiece to get to the brightness you prefer.

 I have a moon filter that helped a lot when i used it in a AT102 ED at F/7..  The TMB is so sharp so it would be a fun solar scope once more spots start showing up. One day things will start to heat up again.
