Thanks for the feedback.
It is a DIY occulting bar. It is made from aircraft engineer’s grade aluminium adhesive tape which is simply stuck to the eyepiece’s field stop. Works a treat. The secret to these is to not have the bar obscuring the central area of the FOV. The central area has the best optical performance and is the spot to place the faint target.

I noticed a bit of a high pressure system around east coast of tassie on BOM earlier this week, seems to be buffering you guys from the waves of lows that are smashing some of us... glad you've been able to make use of it  |
