Very cheap telescope with good optical properties

After 30 years without a telescope, I bought the Celestron SLT. 127
The device is relatively easy to be assembled and disassembled very easily and is therefore also very suitable as travel telescope used. The optical performance is very good at Lunar and planetary observation. Due to the opening of "only" 127 mm Unfortunately, only the brighter deep sky objects "accessible".
Very comfortable is the goto mount, the quasi eliminates the loss of time during object searches. The tracking also works with sufficient accuracy. Due to the azimuthal mount Astro-photography is not possible because the rotating image. For the visual observation, the part is very well suited. I still have an eyepiece (5.2 mm) to buy to get the highest magnification. A power supply (12V, 750mA, 1000mA better), it is best to also buy the same.
