Warning notes
- Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
- Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The use of the solar filter is only intended in connection with this telescope.
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Check the secure fit of the solar filter before each solar observation. An accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
- If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
- Be extremely cautious when observing the sun. A brief look through the unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
- Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not observe the sun after eye surgeries or other eye conditions without prior medical consultation.
- Wrinkles/creases in the film are normal and do not indicate a product defect.
- Do not expose the device to high temperatures.
- BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids. Liquid may penetrate the battery's circuits, causing corrosion and compromising its safety. A wet or damp battery should NOT be dried with a device or heat source (e.g., hairdryer or microwave).

EXPLORE SCIENTIFIC 1.25" CLS Nebula Filter
£55.00*
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer. The EXPLORE SCIENTIFIC CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x CLS filter

EXPLORE SCIENTIFIC Filter Set 1 Moon & Planets from 50mm (2'')
£42.00*
Filter Set 1 is recommended for Moon & Planets from 50mm (2'') Aperture
Set 1 includes the following filters:
Explore Scientific Filter 1.25" Light Yellow No.8 - 0310268
Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn.
Explore Scientific Filter 1.25" Orange No.21 - 0310273
This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter.
Explore Scientific Filter 1.25" Blue No.80A - 0310264
The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer.
EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245
The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.
What ist a color Filter for and do we really need it?
Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.

BRESSER USB Motor Focuser for HEX and R&P
£219.00*
The BRESSER USB Motor Focuser for HEX and R&P lets you achieve pinpoint focus on your telescope remotely and without any physical contact – whether you're enjoying a casual visual session or pushing the limits of astrophotography. The EAF works with hexagonal (HEX), rack-and-pinion (R&P) and most other standard focusers, connects in seconds via USB-C, and gives you the choice between manual control via the hand controller and fully automated focusing through your astro software of choice.
Hands-off focusing via hand controller
The included wired hand controller lets you dial in focus from a distance without laying a finger on the telescope. For astrophotography, this is a genuine game-changer: imaging sessions run uninterrupted and your focus stays locked in from first light to the end of the night. Visual observers will appreciate it just as much – precise focus adjustments on demand, no fumbling in the dark.
Autofocus and broad software compatibility
The EAF integrates smoothly with the most popular astro software packages. The ASCOM driver covers the vast majority of Windows-based applications, while full INDI and INDIGO support makes it equally at home on Mac and Linux. If your software includes an autofocus routine, the motor will handle everything automatically – a real asset for long, unattended imaging runs.Temperature sensor for sharp results all night long
As the night progresses, temperature drops can cause the telescope tube and optics to contract slightly – enough to nudge your focus point off target. The included temperature sensor tracks these changes continuously and, paired with compatible software, compensates for any thermally induced focus shift on the fly. The result: consistently sharp images from dusk till dawn, with no manual intervention required.Please note: The temperature sensor and hand controller cannot be used at the same time.
