This popular desiccant cap has a dual diameter nosepiece to fit both 1.25" and 2" focusers.
Red anodised screw cap and black-anodised cup. Made entirely from CNC-machined aluminium (no plastic!).
Designed and manufactured in the UK.
A sachet or two is placed in the cup then the lid screwed on. A captive O-ring ensures the cap fits snugly into 2-inch focusers and the lid is air-tight. The desiccant draws moisture from inside the telescope tube through the cap's breathing holes. Used regularly the cap will prevent moisture harming the telescope optics.
The desiccant starts yellow then turns green when it can no longer absorb moisture. The desiccant sachets can be dried on a radiator then reused several times. Replacement sachets are available.

I've actually got two of these, one for my Equinox 120ED and one of Evolux 62ED. They are very effective at preventing moisture build-up inside the lens. Very important if you want to avoid wrecking kit that you've invested heavily in, worth every penny.

A well made and well fitting aluminum desiccant cap. The lid unscrews to allow the desiccant to be placed inside. The desiccant beads change color when full of moisture. Great for peace of mind. First class service from FLO

Does exactly what it says but be aware that it only is a very loose fit in a 2" Baader click lock. You will need to fit it to a 2" to 1.25" adapter to gain a tight fit.

SEEMS TROUBLE FREE, JUST POP IT INTO THE EYEPIECE HOLDER. NO INSTRUCTIONS ,SO NOT SURE WHETHER HOW MANY BAGS TO USE OR SHOULD IT BE USED LOOSE ( DOES THE MOISTURE EXTRACT THROUGH THE PLASTIC? )

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 .

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

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.
