Can’t determine make/model

[Dkz]

I need some help determining the make/model of a telescope I inherited so I can download manuals. Thanks

It looks to be from the same family of scopes as the Orion SkyQuest XT Classic Dobsonians.

Hello and welcome to the forum 🙂

The scope looks very, very similar to the dobsonians made by GSO and sold under a number of brandings over the years, including quite possibly the Orion (USA) dobsonians that @Louis D has linked to above.

Here is a link to the (rather basic) instructions for the GSO 150mm dobsonian:

N:\圖面-12\( D 作業指導書 )\C\580C\GSO-580C_01 Model (1) (teleskop-express.de)

and here is the same for the 200mm (I can't quite work out which model you have) which is a little more comprehensive:

You will probably find that the Orion instruction manual in @Louis D's link more useful though - Orion have always provided decent instructions with their equipment, which is not something that can be said of all brands.

Defo looks like a GSO/Orion... 
But even if it is not, it actually is not relevant. Assuming you are not proficient in the domain (sorry if you are and what follows is patronizing) , if you give us carefull dimensions (diameter of main mirror, tube length) anyone with even minimum experience will be able to calculate the main optical characteristics (focal length, F ratio etc) and to point you to the relevant infos for a good start.

It is not essential to find the instruction manual or identify the precise model. As others have pointed out, this is a Dobsonian mounted Newtonian telescope - a relatively low-tech device, and when fitted out with standard eyepieces and a standard optical finder can be used in a standard way.  

Of course, if any bits are missing you may need our advice for sourcing replacements.
