Do you have a question about the Omegon Dobson Advanced 203 and is the answer not in the manual?
Assemble the telescope base by connecting panels and discs, then attach the optical tube to the base.
Adjust the disc position to match the knob's tip to the recess for optimal performance and friction.
Install the focuser by releasing and retightening set screws to hold the base tube securely.
The finderscope aids object location. This telescope uses Vixen-compatible findershoes.
An eyepiece rack holds eyepieces and accessories for quick changes during observation.
Observe craters and features like the Marea on the Moon. Best seen when not full.
View Jupiter's disc with two bands and its Galilean moons: Io, Europa, Ganymedes, Callisto.
See Saturn's rings, discernible at 60x magnification, and potentially Cassini's division.
Calculate magnification by dividing telescope focal length (1200mm) by eyepiece focal length.
A Barlow lens multiplies the telescope's focal length, increasing magnification.
An erecting lens provides an upright image and increases magnification by 1.5x.
Identify parts of the red-dot finderscope, including the red-dot case, controls, and bracket.
Install the battery, turn on the finderscope, and attach its bracket to the telescope's finderbase.
Align the red-dot by centering a distant object in the telescope and adjusting knobs to match the dot.
Replace the CR2032 battery when the red-dot dims. Turn off the finderscope when not in use.
