Your 8" f/6 probably weighs more than that. Also, the diameter of the OTA would interfere with the az hub/tripod top. Compared to the EQ5 you have, are you looking for something with more stability, lighter weight, alt-az,...? -------------------- 17.5" f/5 Dob. IM-715 MCT. 120ED. Lunt 60mm Ha.

I use an Orion SkyView AZ mount. I find it works well with either or both of my ~ 16 lb OTAs and it might be OK with your 8" Newt depending on its weight. I don't know if it is available in the UK.
