Thanks for that Malcolm, the filter slide looks like the ideal solution!
Picked up the Ethos and a 2x Powermate, a glatter laser collimator and tublug, and a few other odds and ends. I was blown away by the Ethos, I'm still very new to astronomy and until I got the Ethos I was using the 10 & 25 Plossls that came with the scope and while I was enjoying looking through them, I hadn't been "wowed" yet. I've spent the last week or so camping in the Snowy Mountains... proper dark skies down there, and the views through the Televue were incredible!
Next on the list are the 21 & 8mm Ethos, a 4x Powermate. That set should keep me happy for a long, long time I think
