Both of its cornerstone components are \u003cstrong\u003ediscontinued\u003c\/strong\u003e: CFF Telescopes ended production of the 250 mm Ritchey-Chrétien, and Astro-Physics discontinued the 1100GTO-AE in 2025. The CFF's hand-figured Supremax 33 primary in a carbon fibre truss chassis delivers the thermal stability and pinpoint stars that a 2000 mm imaging train demands, while the AP1100's absolute encoders reduce periodic error below 0.2 arcseconds and let the mount recover its exact position without a re-sync — the single most valuable trait a mount can have when you are operating it from two thousand kilometres away.\u003c\/p\u003e\n\u003cp\u003eBehind the optics sits a matched, no-compromise imaging train: the 26 MP QHY268M mono camera with off-axis guiding through the QHY OAG-M Pro, Astrodon LRGB and Antlia narrowband filters, Starizona direct-drive focusing, and an EAGLE5 PRO running the whole rig over the network. Add the TS 0.8× reducer and the same scope becomes a wider f\/6.4 instrument for larger targets. Assembled new today, the components in this list would represent roughly 35,000 USD before shipping and duty.\u003c\/p\u003e\n\u003cp\u003eFor a buyer who wants dark-sky imaging time rather than a construction project, this is about as close to turnkey as remote astrophotography gets.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Sale\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis item is sold as a Final Sale.\u003c\/strong\u003e All used equipment sales are final, and the condition is described above in good faith.
