A Kraft Peanut butter lid fits perfectly for the 77mm Eikow. (Polaroscope)
No felt needed...tight fit.

...and the finder has a Maple Syrup lid. Had to use a little felt to secure this one.

Yeah, but I didn't want a possible mod issue so I strategically faced the labels away. I don't drink.

A local person had around 75 of these including some nice black ones (towards the back in the picture). I've used them for years as various grab bags of astro gear and also cover my secondaries on the big dobs. I've never had a lint or fuzz problem. I'll still use the elastic bowl covers under them, but I think they will dress up the capless scopes over the covers.

One thing not covered very much in this string is large secondaries. I use a styrofoam cup that snugs to the secondary holder, then bag the whole thing with the CR and drawstring. Been doing this for way many years.

My dewshield for my 6" F5 refractor came from Bed Bath & Beyond. it's a stainless steel canister. I had to cut off the bottom and make a ring spacer to fit over the objective cell. As a bonus it had a very flexible but tight fitting black rubber cover that fits over the slightly belled out rim. You can see the separate pieces in the upper left photo. The notches are for access to the collimation screws. The scope, dewshield and cover are all assembled in the right photo.

I have found thin black craft foam to be quite suitable for use as a dew shield on 'scopes 4-inch aperture and under, when cut to proper size and secured to itself with self-adhesive velcro strips.

I just found an adequate dust shield for my Meade SN6... a lid from a 7cup Pyrex container. It won't fit around the OD of the corrector cell, but it will fit snug on the ID. No modification needed. :)

Tuna cans were a perfect fit for my Royal Astro R-61D 60mm f/20, and more recently acquired Tasco 9TE-5. The can for the Royal Astro is from the 60's, as you can tell by the edges. Fortunately, the newer cans in the larger size still fit the larger dew shield of the Tasco perfectly including room for the felt liner.

Hi I used a very cheap door mat, rubber on one side and thin corded material on the other quite thin but very hard a solid when rolled around the existing dew shield I put the rubber face to the outside so any dew runs off and the cord surface inside so it absorbes any moisture at least that is the theory as per the attached pic

A small styrofoam coffee cup makes a perfect end cap for Zeiss Telementor. An absolutely perfect, snug, but not tight fit, and infinitely replaceable.

C5. Fits nice and snug with a little felt. I posted this some time ago in a separate thread but it fits well here.

They came out with a Gourmet Blend - it's pretty good for pre-grinded but all the blends have the same cap. If anybody needs a cap I have a few lying around. Just cover the first class shipping - I have the envelopes. :cool:

I'm a good boy. I now wait until the container is empty.
I once made the mistake of transferring Cheryl's protein powder to a ziplock and running off with the prized container, BIG MISTAKE :crutch:
Now I wait and it takes a long time so when I get one its a special event to see which scope the ruby slippers are going to fit.
Whats great is these come with a cap and they are cardboard but moisture resistant which is lightweight. You just use a can opener and cut the bottom out, cut the top off.
The lucky winner this time is a 92mm I made. ID of this particular container is a very difficult to find 3-7/8" I'll try it out before I cover it with model airplane covering.

I made a Bahtinov mask for my Questar 3.5, using the black plastic lid from a can of Kroger peanuts and an Exacto knife to cut the pattern. The bad news is that, after I cut the slots, the remaining plastic was too limp to remain in a plane, so I scrapped the whole project. The good news is that I really didn't need it anyway, since I'm strictly a visual observer. The lid was a perfect fit, though.

I still use a $1.00 piece of poster board for a dew shield on my 8" SCT. A shoelace holds it in place.

I also made a poster board one for my C5. I wanted to show in this photo the overlap with staples at each edge, this technique seems to result in a rounder tube.

This very clever cap was on the scope when I bought it and probably still is on my old Coulter red tube which I no longer own.
The reason I say probably still is is because it worked excellently.
Here's the inside. Custom fitted cardboard:

This one is 40+ years old and came on a Joseph Cocozza Edmund Scientific 4" refractor.
