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:
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.

Hi to everyone,
I'm new in the world of the telescope and as my first telescope I bought an used Skywatcher 70/700 with supatrak mount and I hope that someone can help to understand the equipment I'll need to connect (cable, bluetooth or wi-fi add) my telescope mount to a Mac and control it by software like EQMac or Stellarium.
Brand new to the forum but I've been amateur stargazing for a while. For the last 10 or so years I've been using a 4.5" aperture Dobsonian and it's been great but I think it's time for a large upgrade. There are so many options out there I wasn't sure where to start as I'm mostly just familiar with my own telescope and how it works. I'm looking for a step up and don't know whether I should stick with a Dobsonian and just get a larger aperture or try something else like a reflector (and if so, where to start). I love looking at planets and deep sky objects. I don't mind the size as long as it is generally portable. Preferably under 800USD but flexible.
Thanks so much for the advice!
