From time-to-time I see posts and responses in various places mentioning the use of plastic caps and cans from everyday items available at the grocery store that can double as dew caps or dew shields.

I though it might be useful to have a place to post this information in one place so everyone can benefit.

Please post all the information you have. If you want to know if anyone has found something just ask and hopefully someone will respond.

Thanks!

Fits perfectly. The only down side is that you can't get it off with the dew shield on as there isn't a handle. But other than that it sure keeps the dust off!

I have used all manner of tin cans and plastic lids and even a Quaker Oats cardboard canister. Working in food service I have access to all sorts of tin cans etc and I am always on the out look. I even found some decorative Christmas candy tins that fit my Carton cell like a glove. It is all about being creative.

The factory cover is over the lens cell. But I don't want dust in the dew shield nyther.
If you buy this dew shield cover they throw in the butter for free. Safety red.
You do get some funny looks measuring everything in the store. A lab coat and clip board helps.

My Sears 6345 dew shield slipped off rolled out into the street and was squashed flat by a passing car. And why am I not in a box 6ft under after something this traumatic? it happened before I bought the scope.
I made a replacement out of this container and it came with a cover. I cut it to length, cut the bottom out with a can opener to leave the metal rim reinforcing the outside edge and for the lid (cover) to grab.
Next I covered the outside with self-adhesive white model airplane covering film, inside is self-adhesive black felt.

This particular container could be a industry standard size and use other labels but it fits the 6345 cell.

Nice. Can you post the picture of the finished dew shield here? I saw it in another post but it would be great to see it here. It was very impressive!

I forgot I have this picture. The model airplane covering material is a little see thru in white but peel and stick and available in many colors. Any hobby shop will have it.

I found an aluminium tin of Italian coffee, proved most useful for a dewshield on my Carton 60/1000. I matt blacked the inside and sanded down the inside. Tres pleased.

I need a plastic cap, 5.375" ID, for the dew shield of my Carton 100mm. So far no luck finding anything to fit.

My sleuthing search for truth on an old finder cap.

This is the finder from Gramps telescope. Being an ATM works, this is the original jar cap cover. It has been nicely fitted with a red felt that lips perfectly onto the finder. (side note: the finder is solid machined brass from 1/4" to 3/8" thick).

Here is the insert. I decided to keep this as original equipment as the felt has been pemanently attached. This prompted me to investigate the mysterious cap for a positive I.D.

As the picture shows, there remains a scant scattering of print and picture both on top and around the edge. The edge was my best start with the single string of fractured hierogliphics easier to follow. With some magnifying glasses I started in on a game of hangman. First noting the most recongnizable characters, then filling in with only those options that made sense and fit the remains without question. After some time the answer leaped out in Vanna flash of Wheel, "Refigerate After Opening, Do No Freeze".
WOW, the revelation created a total sense of dissappointment!
On to the top for pictures and an unkown sequence of unknown font. The same technique with satisfying result gave:

8" Optical Craftsmen, and probably most Parks tubes. Dock piling cap. PVC and a perfect fit. Also will Prevent birds from perching on your instrument.

I am in the process of using a shipping tube for a dewshield on a Carton 60mm Classic objective. LINK
