Good Afternoon All,

I am offering for sale on behalf of a friend of mine an original 25”/F5 Obsession Telescope with Nova Optics primary. The scope is just over 10 years old and belongs to a friend of mine who previously worked at the Compact Array Radio Telescope facility at Narrabri, but is now based in Sydney and has nowhere to store the scope. The scope is still located on site at the Compact Array facility at Narrabri and would need to be picked up from Narrabri. Given enough notice the owner could arrange for transport to Sydney (after sale only as he has no way to store the telescope in Sydney). The telescope can be inspected at Narrabri by prior arrangement.

There is some slight surface damage to the finish on the front face of the mirror box. This is cosmetic only. Two of the split blocks will be in need of repair soon, but are currently serviceable. This would be a minor repair by simply ordering two new blocks from Dave Kreige at Obsession telescopes. Apart from the two damaged split blocks and the deteriorated cosmetic finish on one face of the mirror box the structural integrity of the scope is very good and solid. The primary and secondary mirrors are in very good condition as they are usually stored in their shipping boxes, when the scope is not in use. This is a bare bones scope fitted with a JMI single speed focuser. If you’re not worried about looks two new split blocks and the scope is good to go for many more years. If you are worried about looks two new split blocks and some sanding and varnishing has it is good as new. If you did want to refinish the woodwork this would be a perfect time to retrofit accessories like Argonavis and Servocat.

Included with the telescope is:-

- Primary mirror (engraved): Nova FL 121.5" Serial # 400-1075
- 3.5" Astrosystems secondary mirror
- Telrad finder
- Brand new light shroud (not in the pictures)
- Meade 8.8mm 2"/1.25” Ultra Wide Angle Eyepiece
- Meade 40mm 2" Super Wide Angle Eyepiece
- 2" Lumicon OIII Filter
- 2" Nebula Line Transmission Filter (OIII 496nm, OIII 501nm, Hbeta 486nm)
- 12V fan for mirror cooling

The asking price of the Scope is $10,000 including all eyepieces and accessories, or $9,750 for the scope only without eyepieces and filters. The price is negotiable. Keep in mind that a 25”/F5 primary mirror alone will cost $10,000 shipped to Australia.

The filters and eyepieces are in excellent condition.

Anyone interested should contact me and I will put you in touch with the scopes’ owner.

Cheers,
John B
