My 152 ED has been modified with an AP 2.7" focuser, with extension tube and 2"-1-1/4" adapter with brass ring; JMI motorized focuser unit with Digital read out; custom machined rear aluminum plate to fit AP focuser. 2 sets of rings - new Parallax set, another lighter duty set. An AP case modified to fit. Very nice optically - well collimated. I'm a double star observer and used this at high powers of 400-550x with great satisfaction. Selling because I got a larger aperture TEC Mak. I love this scope, my first really big modification effort; but I can't keep more than 4 scopes and still live in the house. Would possibly trade for STV deluxe with efinder, or ST-4 plus cash, or sell for $2000 plus shipping. Solid offers listened to. Any questions send me an email. I have good pics that I can't seem to get onto Astromart - the woes of a Mac owner. But I can email them to you.
Thanks everyone for all of your inquiries!
