Description
The BYOMIC G reflector telescope 114/900 is a compact telescope with a large Newtonian mirror. The advanced astronomer knows that the incidence of light plays a major role in the quality of telescopes. The 114 mm mirror focuses a lot of light. This makes it easy to examine celestial bodies that are far away from the earth. With a mirror of 114 mm diameter and a relatively long focal distance, there is a focal ratio of F/7.9. The EQ-SKY mount makes it easy to track celestial bodies.
We also recommend that you purchase a star chart or software to help you locate celestial bodies. A worthwhile addition to your telescope.
Even more important than with photography, a stable and wobble-free tripod is of great importance when handling telescopes.

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.
