  • Page 3: Scope Of Delivery

    • Scope of delivery The scope of delivery of the TSCOLLIT includes a controller for the integrated illumination and two eyepieces. One of the eyepieces is already mounted on the collimating telescope, the cor- responding 1.25“ socket is included.For the in-...

  • Page 4: Using The Eyepieces For Observation

    You can use an alignment laser with a 1.25“ connection instead of the eyepiece tube. Because of the optical elements integrated in the TSCOLLIT, not a dot but a circle several millimeters in size is then projected onto the secondary mirror.

    · Attach the TSCOLLIT to the focuser flange using the appropriate adapters. · Point the telescope at a flat, homogeneous and well-lit surface, such as a white wall.

  • Page 6: What Can Be Seen When Looking Through The Tscollit

    What can be seen when looking through the TSCOLLIT? At first glance, what you see when looking A distinction is made between directly visible, through the TSCOLLIT seems confusing, so single and multiple mirrored elements. the individual elements will first be explained using the image.

  • Page 7: Checking The Alignment Condition Of The Telescope

    Checking the alignment condition of the telescope Look through the TSCOLLIT and check whether an adjustment is required. If the secondary‘s mark is exactly in the center and the directly and mirrored visible parts of the secondary are in line, the adjustment is OK.
  • Page 8 Note: Adjusting an RC telescope is an iterative process because several parts must be aligned to each other without an external reference. Theoretically, the secondary mirror could be removed and the focuser flange aligned to the center of the secondary mirror mount; this would establish a reference axis.

  • Page 9: Adjusting The Secondary Mirror

    If an offset is visible in one or both directions, pay attention to the secondary holders. the primary mirror must be adjusted. This is Adjust the eyepiece of the TSCOLLIT so that done with three pairs of screws (adjustment you can clearly see both the parts of the and counter screw or pull and push screw).

    Repeat the entire procedure until all the settings are perfect. Mounting and checking the focuser Remove the TSCOLLIT and any adapters used It is often recommended to compensate a pos- from the telescope and attach the focuser. sibly deviating axis orientation of the focuser with the adjustment screws of the flange.

    · Unscrew the focuser and any additional parts such as spacer rings and tilt adapters. · Attach the TSCOLLIT to the focuser flange using the appropriate adapters. · Point the telescope at a flat, homogeneous and well-lit surface, such as a white wall.

    This ring can limit the field of view in a disturbing manner and must be removed if necessary. What can be seen when looking through the TSCOLLIT? At first glance, what you see when looking...

  • Page 13: Checking The Alignment Condition Of The Telescope

    Checking the alignment condition of the telescope Look through the TSCOLLIT and check whether an adjustment is required. If the secondary‘s mark is exactly in the center and the tube-side secondary holders extend the same distance into the image of the primary mirror, the adjustment is OK.

  • Page 14: Adjusting The Main Mirror

    Adjusting the main mirror When adjusting the primary mirror, you must pay attention to the secondary mirror holders. Focus the TSCOLLIT on these. If an offset is visible in one or both directions, the primary mirror must be adjusted. This is done with three pairs of screws (adjustment and counter screw or pull and push screw).

  • Page 15: Adjusting The Secondary Mirror

    IMPORTANT: The retaining screw in the term stability for the adjustment. center must not be loosened under any If the center mark and TSCOLLIT center are circumstances! concentric, the secondary mirror is adjusted correctly.

  • Page 16: Adjusting The Focuser With A Tilt Adapter

    Adjusting the focuser with a tilt adapter Even if both mirrors are correctly adjusted, the longitudinal axis of the focuser flange may not be on the optical axis of the mirrors. Unlike the RC telescopes mentioned in the first section of this manual, it is not possible to set a reference axis independent of the optics in the devices described here, so a tilt adapter (usually not included in the scope of delivery) should be...

  • Page 17: Refractors

    • Refractors Thanks to the bright integrated illumination, the TSCOLLIT can also be used for adjusting refractors. The ring-shaped reflections on the surfaces, which are of different colors (depen- ding on the coating) and sizes, can be highligh- ted or dimmed via the sliding focusing.
