Hi all,
Offering my fully upgraded and optimised 10" f/4 (254/1016mm) GSO / TS-Photon Newton OTA, ready for serious astrophotography. Removed the bottlenecks from the original GSO design — all the 'hard' work is done. Just mount and image.
Upgrades over stock configuration:
Why this OTA stands out:
One thing to note:The Aurora Optics mirror cell upgrade slightly shifts the backfocus inward compared to the stock mirror holder. In practice, a coma corrector needs to be positioned slightly further outside the focuser than usual. Flat frames are recommended for larger sensors.
Sample images: The attached images were taken with a ZWO ASI2600MM and ASI6200MM Pro — they can use more integration time, but it shows what this telescope is capable of.
Included:
Not included: mount, cameras, EAF, cables or any other accessories visible in the photos.
Asking price: €1.100 — serious offers are welcome.
Reason for selling: I already have an EdgeHD 11" for home use and I'm looking to add a portable travel setup that fits in carry-on luggage — so this OTA is looking for a new home with someone who will put it to good use.
Located in Halle, Belgium. Pickup preferred. Shipping possible at buyer's expense.
Feel free to ask for additional photos or any questions!

Upgrades over stock configuration:
- Aurora Optics 6-point primary mirror cell with built-in cooling fan
- Backyard Universe CNC secondary spider
- Baader Steeltrack focuser with ClickLock + ZWO EAF bracket
- Losmandy + Vixen dual dovetail
- Full interior flocking
Why this OTA stands out:
- Rock-solid collimation stability thanks to the Aurora Optics mirror cell — no mirror shift or sag
- Baader Steeltrack delivers rigid, tilt- and slip-free focusing
- Beautiful JWST-style diffraction spikes courtesy of the BU spider
- GSO optics are well-regarded: diffraction-limited performance with good PV values
- 1016mm focal length — ideal for galaxies, nebulae and narrowband imaging. Can be further reduced to around 760mm with the Starizona NEXUS reducer for very fast imaging (ideal for lucky imaging)
