Trying ETX 80 (just got it second hand here on Monday). I found a) I cannot use the Celestron C130MAK to focus my Sony Nex3 using the back hole (the thing fit) b) I found out that (but too late) that I can use the built in barrow plus a T ring + eyepiece adapter to focus a building in daylight c) I ...

Got it and worked so far. In fact, the Celestron C130 Mak back hole is the same as the Meade ETX 80.
