Antlia Ultra 3.5nm Ha Filter - 1.25" - was $250 now asking $200

Time to face reality and abandon my plans to run multiple rigs concurrently, so here's a chance to grab some very-nearly-new astrophotography gear.

$250 including postage if required.

This 3.5nm Ha Filter is basically new - it's been mounted in a filter wheel for less than a month, fitted wearing gloves, and kept in mint condition. $299 from Testar RRP - if you can find one in stock - grab this one for $50 off the best price I've seen and dive into narrowband Ha photography!

Pickup from Eltham North but I'll happily post this item anywhere in Aus included in the $250 price.

Edit: I've got 2 Ha Filters for sale, so I've attached a picture from each. It's not exactly apples v apples - different scopes at different times, but it allows you to see a rough indication of the difference between the 7nm and the 3.5nm (the 7nm has the diffraction spikes).
