With the weather being very cloudy and rainy, its been more like late Autumn than mid-summer here in UK 🙁 We planned to do a number of practical related blogs relating to the Moon and Sun with the Celestron NexYZ smartphone adaptor…but for the last few weeks both celestial bodies have not been visible (or just visible through cloud)! So while the sky is cloudy, maybe it could be time to think about giving some of your equipment a clean after its last use for next clear sky or readiness for the glorious autumnal skies.
Celestron offer their Lens Pen cleaning accessory for cleaning a range of optical equipment. As its name suggests, it is a cleaning tool that looks like, and is not much bigger, than a (writing) pen.
The Lens Pen has two cleaning “tools”. At one end there is a retractable soft brush for gently brushing away dust or other loose debris. The other end of the pen features a 14mm circular soft pad that uses a dry (non-toxic environmentally friendly) soft compound for removing stubborn marks such as fingerprints, eye-lash oils, dried water marks etc. The cap that protects the circular pad, has an insert that replenishes the cleaning compound on the pad when replaced.
The pen can be used on camera lenses, eyepieces, objective lenses on refractors and binoculars, Schmidt Cassegrain/EdgeHD corrector plates, imaging sensor optical windows and more (I often use it to clean my glasses!).
The Celestron Lens Pen is small and light enough that its ideal to always have handy in your telescope accessory case or your camera bag especially. It is also ideal to have when going away on holiday, as the Lens Pen uses a dry cleaning compound so there are no liquids to worry about!
This very useful, popular and inexpensive cleaning tool is available from your favourite astronomy retailer.
