I use this eyepiece mainly with my 152mm refractor. They're like a match made in heaven.
If you're concerned about the payload of your mount and the strength of your scope focuser, then it's not the one for you. It weighs more than 1Kg and it does tip the balance of the telescope.
I really love it, the eye relief is...well..such a relief. Image quality is fantastic, no astigmatism or false colours anywhere. Sharp images edge to edge.
Best suited for deep sky objects.
