Page 7: Design Of Telescope
Design of telescope Optical tube is a telescope itself. All the main optical assemblies are mounted into it: objective lens with corrector, eyepiece assembly with focusing mechanism and optical finder. According to the type of optical scheme the telescope refers to the apochromatic refractors. -
Page 8: Preparation For Observations
Preparation for observations Mount the bracket of finder (1) onto the telescope tube and fix it with Assembling of the screws (2). Fix the finder with telescope a screw (3). For the period of observation take off the cover from the blend of telescope tube and from the eyepiece tube. - Page 9 Set the image of chosen object in the crosshairs of finder’s reticle by turning it in spherical joint of the bracket (1), and fix this position with the help of the screw (). In future, it will be enough just to check the coalignment of the optical axes of the telescope and of the finder, prior to observations.

Page 10: Observations 0
Observations At high magnifications, along with increase of the visual sizes of the object, the atmosphere become more significant, that appears as distortion and blurring of images of the distant objects, blinking and blurring of the stellar images. There can be the nights with poor images of celestial bodies because of the atmospheric turbulence. -
Page 11: Photographic Observations
Use a miniature reflex camera with an objective’s thread M4×0,75 to take Photographic pictures of celestial objects. observations To mount a camera on the telescope, take off deflecting mirror () and bushing (), unscrew the camera objective lens. Screw a reducing bushing ” in the ... -
Page 12: Maintenance
Maintenance In order to keep the telescope in good operating condition it is necessary to check it’s technical state and fulfil maintenance. Keep the telescope clean and protect it against physical damage to provide no-failure operation of the telescope. Periodically wipe off the dust from metal surfaces with clean soft ... -
Page 13: Telescope Alignment 3
Telescope alignment The necessity in additional alignment of the telescope can appear after optics cleaning or accidental misalignment. The telescope alignment should be held by specialists, as it requires special skills and qualification. -
Page 14: Storage 4
Storage It is necessary to store the telescope in a dry heated place with a temperature range of +5° to +40 °C and relative humidity up to 80%. Avoid impacts and sharp shocks of telescope. It is prohibited to store acids, alkalis or any chemical materials, ... -
