Note:

We are using a new lens cell design in the WO Pleiades series telescopes. This design incorporates the use of high-quality FPL-53 glass for superior optical performance. Before storying your telescope, it is crucial to allow it sufficient time to acclimatise to room temperature. Please ensure that the telescope is thoroughly dry and free of moisture or dew before storing. This ensures the safety and longevity of the telescope's components. 

Always store the telescope in a consistent temperature and dry environment to prevent any potential damage to the optical elements. Remember to leave the tube uncovered and opened during the acclimatisation period. As always, taking appropriate care of your telescope will ensure its optimal lifespan.
