Orion Optics 12" F4 Ultra grade mirror set with primary cell
Hi everyone,
I have for sale an Orion Optics 12" F4 Ultra grade mirror set. The mirror is just over 5 years old as indicated by the serial number etched on the back of the mirror (see image attached reverse date order). There is an orion optics 75mm secondary mirror with holder and hub to complete the mirror set.
It comes with the 9 point CNC machined 12" primary cell made by OOUK.
Ultra grade optics from OOUK are 1/10 pv and have a minimum strehl of 0.99. The focal length of this mirror is 1174mm.
I am the second owner of this mirror and the coatings are in good condition. There is a tiny mark on the mirror from the previous owner which I have tried to capture as best as possible in one of the images attached. Under torch light I can see the previous owner has rubbed this spot a little. The mirror centre is marked with a very lightly etched X.
It also comes with a stronger fan, heavier springs and a couple of catseye collimation hotspots should upgrades from the standard wish to be made.
Selling price is $1300 which is less than half price! Local pick up preferred but shipping can be arranged at buyers expense.
