Sky Guides by Bresser
Excellent for entering into the hobby of astronomy: 90mm aperture delivers 200 times more light than the naked eye! Observe craters, valleys and rims on the moon from nearly 400,000km away just as you would look out of the window of a spaceship!
The MESSIER AR-90L does not only provide highly detailed views of the moon: Gaze at the division of the rings of saturn millions of kilometers away or explore the Great Red Spot of Jupiter, a giant tornado in Jupiter's atmosphere. Watch the seasons on Mars and find the sickle of Venus.
The MESSIER AR-90L gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.
This telescope is an optical tube without mount and tripod.

Warning Note 1: | 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 sli |
Warning Note 2: | 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. |
Warning Note 3: | 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 teles |
Warning Note 4: | 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. |
Warning Note 5: | 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 tel |
Warning Note 6: | 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. |
Warning Note 7: | Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised. |
Warning Note 8: | Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight. |
Warning Note 9: | Do not observe the sun after eye surgeries or other eye conditions without prior medical consultation. |
Warning Note 10: | Wrinkles/creases in the film are normal and do not indicate a product defect. |
Warning Note 11: | Do not expose the device to high temperatures. |
Warning Note 12: | 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 |
