J'apprécie ce produit pour sa qualité de construction qui est tout en métal . Cela doit bien fonctionner pour chasser l'humidité dans un tube fermé .
Il fallait y penser !

Your scope needs this . Look after the insides of your scope so the moisture doesn’t ruin the lens coatings etc. A must have for taking care of your optics .

Nicely made and it works as expected.

Nice design and well machined. Fits eyepiece nicely and keeps the scope dry as I store in the garage.

If you store your SCT outside or in the garage then these great caps keep all the moisture off your mirrors. When you finish on a cold night all the dampness is absorbed and you need not worry. Highly recommended!

I use this to help keep the optics of my ED80 dry when the scope isn't being used, for periods of time.

I like the quality of this cap, it is strong since being made of aluminium and it fits easily into both 1.25" and 2" focussers.

Colour changing desiccant sachets make it easy to know when they need changing, and can easily be dried out for use again in the future.

Overall, I am glad I purchased this item, something that isn't very expensive and can help 'take care' of your telescope.

Very impressed with the quality of this item and although some might think not cheap, it is in my view a small price to pay and good value to protect the significant investment I have in my observatory housed OTA
