This optical design of the apochromat ensures an absolute minimum of chromatic aberration and provides a very sharp image!
This affordable, short focal length refractor is ideal for the astrophotography of large star fields without the need for a heavy duty astronomical mount. It is also ideal for when traveling or for portable astrophotography in general. The sensitive focuser with a 1:11 reduction gearing is a great help when focusing.
This telescope is designed as an astrograph, that is, the focal position is designed for astrophotography.
It is not only important which telescope you buy, but also where you buy it.
