Obsession 12.5 inch for sale

Obsession 12.5 inch

For Sale for Euro 3,500.oo is my Obsession 12.5 inch Dobson Mounted Newtonian reflector.

The learning curve for this system should be considered with telescope set up, collimation and DSC use so  is not a good choice for a novice but will reward a more experienced visual observer who has access to a dark sky site, with outstanding views.

I purchased the telescope in 2004 and specified the following options : JMI focuser, Shroud and Telerad finder, Argo Navis DSC (encoders, cables and handset) and I asked that it be balanced for TV Nagler 20mm type 2 eyepiece.

Over the years I replaced the secondary holder with a Telekit 4 bolt holder making it easier to climate
and it holds collimation much better than the original 3 bolt secondary holder. Later when it became available I installed a Howie Glatter Wire Sling making the mirror easier to center in the mirror box.

After around 5 years use the mirror coating started to flake off. I selected Orion UK to recoat the mirror. They tested the mirror and reported that it was ok but could be refigured to Ultra Grade and then Hilux coated, over the last 15 years the mirror coating has stayed perfect and the views are excellent.

Finally I added a Stalk to hold the Argo Navis handset.
Overall the telescope has lasted very well, the woodwork shows no warping or splitting the dovetail joints are still tight the varnish hasn't faded or worn off.

The mirror cooling fan is standard, additional items include in the price are:  all three TV Nagler type 2 eyepieces (20mm, 16mm and 12mm),  Howie Glatter 2 inch collimator with Blug and 2 alternate reticule's, a boxed set of Catseye Collimation Tools, mirror has the Catseye Hot Spot for ease of collimation.

Pickup from Vranic, 45 km from Belgrade, I can't deliver as I don't drive.

Reason for the sale is, I'm into my seventies and the effort to use the scope is too much for me.
