I'm selling my my 70mm secondary mirror I used with my 150mm F4 newtonian for 100$ (final price). Shipping expenses (from Beirut, Lebanon) on me for free provided I use LibanPost for shipping. We can discuss using other shipping methods and maybe splitting the cost. The mirror is brand new, still have the original package and box, bought the telescope a month ago and used only twice. No scratches, not even dust (images attached). Excellent mirror, no issues whatsoever, 94% reflectivity and optimized for the offset of f / 4 Newtons, but it can be used up to f / 5. It's from TS, made in Taiwan, original price is 134 euros (including VAT) excluding shipping and custom fees. Link below: https://www.teleskop-express.de/shop/product_info.php/info/p10673_TS-Optics-Newton-Fangspiegel-D---70-mm-mit-Halter.html It does not come with the tilt screws and center screw though unfortunately. I can also sell you the spider vanes (1mm thickness) for 6 inch newtonian for 25USD. Also brand new but without the tilt screws and adjustment screws. https://www.teleskop-express.de/shop/product_info.php/info/p11056_TS-Optics-Spinne-fuer-6--Newtons---164-mm-bis-180-mm-Tubus-Innendurchmesser.html Let me know if interested.

I need help choosing the best EP combo for my newest addition, a TS 150mm F5 Newt. Money is an object :\ however exceptions can be made. If it helps I'm in the midst of a DSO fever outbreak. You're all lovely! Thanks! John
