Parts list

Site location
Choose a dark location to avoid interference of dark adaption throughout lights. A flat and stable surface is recommended. Do not observe from closed rooms. Approx. 30  minutes before starting an observation, position the telescope and the accessories in the desired location to allow temperature compensation.

Setting up the tripod
Pull out the tripod legs slowly until the tripod bridge is opened completely. Open the clamping lever for the tripod legs. Pull out the tripod legs to the desired height. Make sure that the bubble of the circular level is in the middle of the circle to ensure a horizontal plane stand. Close the clamping lever for the tripod legs. Loosen the locking screw for the height adjustment. Pull out the tripod head to the desired height. Tighten the locking screw for height adjustment by hand.

Mounting the Telescope on the Tripod
Screw the threaded bolt of the tripod head plate into the mounting connection of the Telescope to attach.
Make sure that the objective lens is pointing to the opposite side of the handle.

Mounting the scope finder
Loosen fixing screws.
Insert the desired accessory into the eyepiece holder.
Tighten the fixing screw by hand so that the accessory is fixed in a secure way.

Using eyepieces
The magnification range depends on the focal length of the telescope and the eyepieces. The magnification can be varied by changing the eyepieces.
Example:
Focal length telecope : Eyepiece focal length = Magnification 300mm : 6mm = 50x
Use an eyepiece with a higher focal length (= lower magnification) when starting an observation.

Using the prism
The prism will be attached to the telescope between the eyepiece holder and the eyepiece. It allows for an image reversal to an upright image.

Using Barlow Lens 3X
A Barlow lens is an optical component that is inserted between the eyepiece and the focuser. Inside it is a minus lens that artificially extends the focal length of the telescope.
The focal length of the telescope is 300mm, in combination with the Barlow lens 3X the focal length is extended by a factor of 3.
Focal length: 300mm + Barlow lens 3X corresponds to a focal length of 900mm.
900mm: 6mm = 150 times magnification.
A Barlow lens is an additional component that contains lenses. Each lens reflects light and absorbs it additionally in the lens material. This results in less light reaching the eye.  Therefore, you should consider when a Barlow lens makes sense, e.g. for planetary photography.

Using erection eyepiece 1,5X
this lens can be used either directly in the tube or in combination with the prism. Note that the magnification factor increases by 1.5 times, e.g. 300mm:20=50 *1.5=75 times magnification.

Viewfinder
Image reversal

Our viewfinder does not have an integrated optical image reversal. In this case, the image is visible upside down when looking through the viewfinder. This is not an error!

Observation

Point the telescope at the desired object (e.g. the moon) and look through the viewfinder. Use the telescope’s horizontal and vertical adjustment to center the object in the middle of the viewfinder’s hair cross. Look through the eyepiece for an enlarged view of the object. If necessary, adjust the image sharpness by turning the focussing wheel. The magnification can be enhanced by the change from an eyepiece with a high focal length (e.g. 20mm) to an eyepiece with a lower focal (12.5mm) length.

Troubleshooting
