Dew can cause problems at almost any time of the year. Especially when it's a bit cooler, tiny droplets of water vapour in the air condense and fog up your telescope's optics. As a result, you can't see anything clearly, but a clear view of the Universe is the most important thing for night-time observations. Omegon dew cap for telescopes - prevents fogging and ensures a clear view! ADVANTAGES: compact and space-saving prevents the optics from fogging up or fogging up velvet finish - black textile coating against dew formation and anti-reflection adhesive strap attachment for secure attachment available for different OTA diameters Which telescopes is the Omegon protective cover suitable for? For all telescopes with an optical surface on the front. This means for example Schmidt-Cassegrain and Maksutov telescopes. On nights with very high humidity, a dew cap can be useful even for Newtonian telescopes, as many observers have experienced secondary mirror fogging. Suitable for telescopes with a front outer diameter of 145-165 m
An upright and laterally-true image thanks to the erecting lens As dusk falls, your telescope is set up and you're looking forward to observing the night sky. That's when it becomes all the more frustrating if you can't find certain objects. It is often difficult to orientate yourself in the night sky with a telescope, especially in the beginning. Not only do you see billions of stars and celestial bodies, but they are all upside down. An erecting lens can solve the problem by providing an upright and laterally-true image. This means that you no longer have to rethink every step and can simply enjoy the view. The highlights at a glance: An upright, laterally-true image gives you more orientation in the night sky Beginner-friendly erecting lens for reflectors (reflector telescopes) 1.5X magnification Suitable for daytime observation with astronomical telescopes More orientation and greater success in observing An erecting lens is a useful accessory and is particularly suitable for those starting out in recreational astronomy. Even if you get used to the reversal effect of the telescope, it is nevertheless advantageous for some observations if the image is laterally true. Finding new constellations by star hopping or targeting a specific detail on the lunar surface becomes so much easier. The lens can be coupled with a 1.25" eyepiece and increases magnification by a factor of 1.5. The lens is of course also great for observing landscapes and animals during daytime.

These eyepieces are versatile flat field eyepieces with exceptionally high image definition, which is clearly noticeable when observing planets and the Moon. Patented EMD tempering provides high contrast and prevents disruptive reflections. With a corrected apparent visual field of 52 degrees, these eyepieces are far superior to simpler Plössl eyepieces. Thanks to the argon gas filling, internal fogging is effectively prevented, and there is no need to worry about dust, lens fungus or cleaning fluids infiltrating. The eyepieces are fitted with a watertight seal. This guarantees many years of unquantifiable observation joy using these high-quality eyepieces. The Explore Scientific 52° LER series stands for the highest level of comfort and quality, paired with an exceptional price-performance relationship.
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics.The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the ”averted vision” technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves.All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
The CBC 5 charger is designed for 6V/12V gel, lead acid, AGM, VRLA, VLA, SLA, WET, GEL, Lead-Acid batteries. Charging is automatic, multi-step. Charging mode, the operation of the charger is indicated on the backlit LCD display.The first step is to measure and indicate the voltage at the battery terminals and determine its type. For a 12V battery, by pressing the ”MODE” button, you can select a charging program (0.8A/3.8A) as well as a ”winter” mode characterized by a higher charging voltage (this is also the default recommended charging mode for many modern AGM batteries). The condition of the battery is assessed and reactivated if necessary (only for heavily discharged cells) - charging with reduced current with single pulses.The next step is basic charging - depending on the charging mode with a maximum intensity of 0.8A or 3.8A.The next steps are to control the charging process - as the voltage on the battery increases, the charging current is reduced.In the final phase of charging, the current is smoothly limited to 0.5A - this is an excellent protection against the phenomenon of ”gasification” of the battery. When the voltage reaches 14.4V/14.8V (for 12V battery) and 7.3V (for 6V battery), the main charge is complete.The final stage is the phase of monitoring the voltage on the battery - in case of prolonged leaving the charger connected to the battery and the voltage drop to 13.1V/12.8V (for a 12V battery), the charger turns on the support charge to prevent further discharge or souscoulation of the battery.
With this 12V/12Ah lead battery you can extend the runtime of your surveillance camera significantly. It is perfect to use in combination with our DÖRR game cameras SnapShot Cloud 4G, SnapShot Mobil 3G and SnapShot Extra black 12.0i HD. This SLA (Sealed Lead Acid) battery is sealed, may not leak and is maintenance-free. It may be installed in many positions, even lateral or tilted.
