I did the big swap of one of my WO ZenithStar 66ED Petzvals for a WO Megrez 80SD Mk1 with Morton (here on IIS). He wanted smaller and I wanted larger. We're mutually happy with the result which is great.
I've attached one of my favourite red dot finders along with a heater for the dew shield, finder and eyepiece.
Views are very good for an achromat. Sharp stars and moon - especially with an Orion 1.25" minus violet filter.
Looking forward to making this the travel scope along with the C8 SCT. Should be great for those 4WD trips away into the bush.
Cheers
Chris
