Free red dot finder from my 6SE Celestron SCT. Comes with a bracket, just needs to be screwed in (I've misplaced the 2 screws unfortunately). Not sure how well the curvature of the bracket will fit other OTAs. Has a working battery inside, and the laser can be dimmed to assist with low light conditions. Happy to post in an envelope anywhere in Australia, or you can pay for a box + postage if you like. Alternatively PM me to arrange a pick up from Melbourne CBD. First come first serve.
