Hi I got a celestron 130eq-md for Christmas and so far iv had very good views of the mood and Jupiter. I bought myself the celestron eye peice kit that comes with a 2x Barlow lens, a 6mm, 15mm eye pieces and some filters. Now for the questions. If I use the Barlow and the 6mm it gives me a 3mm but I can't focus enough to get a better view, could I move the balow and eye peice out a bit more to get in focus or could I get a extension tube to focus more? (if any of that makes sense) Would a 3x Barlow be any use? Would like to use a webcam, I have ordered an adapter tube for it onto the telescope
