Description
The Byomic Dobson Telescope SkyDiver 102/640 is a fantastic telescope for observing the night sky.
The telescope is equipped with a Dobsonian mount, which makes it easy to move the telescope azimuthally (horizontally and vertically). Since the telescope only needs to be placed on a flat surface, you don't need much space. The Byomic SkyDiver 102 mm is equipped with a handle in the holder that makes it easy to carry and move the telescope. If you need to take the telescope on a trip, you can easily transport it as it weighs only 6 kg and does not take up much space.
Inspect lunar craters and see the rings of Saturn or the polar caps of Mars. The telescope collects 212 times more light than the naked eye. With it, you can already spot some nebular objects that are not visible without a telescope. These objects are outside our solar system and often many light years away from us. Discover the Orion Nebula, (1350 light years) in the galactic neighborhood of one of the most active star forming regions, which is why it is a favorite object for studying star formation.
Byomic Dobson Telescope SkyDiver 102/640 is a powerful and simple telescope. As soon as the telescope is placed on a flat surface, it is ready for use. Because of the Dobsonian mount, the telescope can easily move left and right as well as up and down. Once the correct position is reached, it can be locked in place with the convenient locking buttons. The Red Dot Finder's red dot makes it easy to point the telescope at a celestial body. If you look through the red dot and move the telescope so that the red dot is visible on a celestial body, you will also see this when looking through the eyepiece.

Definition: The Water Column of a Tent
The water column indicates the maximum water pressure that a tent fabric can withstand.
A water column of 1,500 mm means that the tent fabric can withstand the pressure
of a 1,500 mm (1.5 meter) high column of water before water penetrates the fabric.
The higher it is, the more waterproof the tent material is.
Waterproofness
The water column is also a unit of measurement to measure the watertightness e.g.
B. of technical fabrics (tents, functional and rainwear).
DIN EN ISO 811:2018
regulates the method for determining the resistance to the penetration of water.
The following “hydrostatic water pressure test” must be carried out: The outside
of the material is exposed to the water. The water pressure starts at zero, the
water column rises by 100 mmWC or 600 mmWC per minute, depending on the standard.
The time is measured until the third drop can be seen on the inside. The pressure
that is acting at this point in time is then given in millimeters of water column.
Top tents are considered waterproof from 1500 mm
and tent floors from 2000 mm according to DIN.
