Picking up a new WO GT102 tomorrow...little brother to the GT153 already on board.
I wanted a smaller refractor for travel to a nearby (40 mins drive) dark site (Bortle 1-2) as the GT153 is a bit of a beast to move and I don't have a portable mount solid enough to carry it for AP use. The GT153 sits on a AP900 mount in the home observatory.
The GT102 allows me to use the pair of WO flatteners and reducers that I got for the GT153 and cost me a small fortune .
So good to go!
