Due to its shortened design, this is known as a so-called catadioptric mirror tele; however, thanks to the mirror used and the built-in double lens, it delivers a large focal length of 1000 mm. With an opening of 114 mm lens, the Delta 30 telescope is considerably more powerful than a lens tele in a similar price range. With the two accompanying eyepieces and the 2-fold Barlow lens you can achieve enlargements from 50-times up to maximum 200-times.EQ2 Equatorial mountingThe EQ2 equatorial mount, also known as parallel-latic mounting, consists of 2 axes: The pole or hour axis (rectassion) and the declination axis for the coordinate setting of the respective object. To fine-tune the two axes, the mount is also equipped with flexible tracking shafts. A balancing weight at the declination axis ensures the telescope is balanced.Tracking motorWith the tracking motor 9 V for EQ-2 mounting, the hourly axis (rectassion) of the earth rotation is automatically tracked. This ensures that the targe
