Frequently Asked Questions - TX-175 TECHNAXX

How to mount the telescope on the tripod?

Screw the threaded bolt of the tripod head onto the mount connection of the telescope. Ensure that the objective lens is pointing away from the handle.

How to use the finderscope?

Point the telescope at the desired object and look into the finderscope. Use the horizontal and vertical adjustments to center the object in the finderscope's crosshairs. The image is vertically inverted (normal).

How to change the eyepiece?

Loosen the fixing screws of the eyepiece holder, remove the current eyepiece, and insert the new eyepiece. Tighten the screws by hand to secure.

What to do if the image is blurry?

Turn the focus knob to adjust sharpness. If the image remains blurry, check that the caps are removed and the eyepiece is properly installed.

How to clean the lenses?

Use a lint-free cloth dry or slightly damp. Never use abrasive products. Avoid fingerprints on the optical elements.

Can I observe the sun with this telescope?

No, never look directly at the sun with the device. This can cause irreversible blindness. Only use the included solar filter to reduce brightness, but never look without the filter.

What is the purpose of the 3x Barlow lens?

The Barlow lens artificially extends the focal length of the telescope. With the 3x Barlow, the focal length increases from 300 mm to 900 mm, increasing magnification (e.g., with a 6 mm eyepiece, magnification 150x).

How to get an upright image?

Use the supplied 45° prism. It attaches between the eyepiece holder and the eyepiece to vertically correct the image.

What is the warranty for this product?

The warranty is 2 years. For any claim, contact the dealer or store where you purchased the product.

How to contact technical support?

You can reach support at 01805 012643 (14 cts/min from a German landline, 42 cts/min from mobile) or by email at [e-mail].

Site location

Choose a dark location to avoid an 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 on the desired location to allow a temperature compensation.

Setting up the tripod

Pull out the tripod legs slowly until the tripod bridge is open 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 the 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 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 telescope : Eyepiece focal length = Magnification

300mm : 6mm = 50x

Use an eyepiece with 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.

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 centre 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.

Trouble shooting

No Image	Remove the caps, change the eyepiece
Blurry image	Adjust the sharpness by turning the focus wheel.
Bad image	Do not observe through glass, clean lenses
