The case that comes with the Sky-Watcher 100mm Evostar ED is pretty nice, but contains lots of cardboard. I sometimes have trouble remembering to close the lids on my gear once I begin to set up. You know how well cardboard and moisture like to get together in the dark! I thought about just removing all the cardboard from the case and replacing it with something else. But I didn't want to have to rip out all that foam so looked for another solution. I think I found something that might work-"plasti-dip". I laid down three coats of plasti-dip and let it dry for a day or two. The cardboard seemed to soak it up nicely until the 3rd coat was applied. I hit the edges of the cardboard heavy trying to seal them. Here is a pic of the results. Sky-Watcher, if you are reading this please use something else that does not attract moisture-Thanks!

As I recall my Skywatcher 72ED came with that stuff in the case. That was about 5 months back.

I know it is a foam and looks very much as the image - glossy black stuff, fairly firm, but it is foam.


Just looked: All internal sections are made from single foam sheets each about 3mm thick, glued I assume together. One is 5 sheets, another 6 sheets and the third is 8 sheets. These form the U shape into which the scope "drops". The 2 ends are rectangles of 8 or 10 sheets - sufficent to hold just compress the focuser end and objective ends inwards .


Seems a bit of an odd construction - lots of glued, either precut or glued and cut sheets.


Seems odd you got cardboard, never heard of it here.

Cool idea! My SW Evostar 120ED came with the same case. The foam is divided by cardboard. I was thinking there had to be some solution without damaging the foam.

I just happened upon this post.  If I'm seeing the photo correctly, that's a fairly straight piece of rectangular cardboard being used as a divider.

In both Home Depot, Lowes and most craft shops, there is a product called Coroplast - which is basically a corrugated plastic.  It seems to only come in white and translucent, as I recall.  The stuff would probably take Krylon Fusion paint pretty well, too, if you wanted to get arsty.  This is what a lot of campaign and realty roadside signs are made of.

Best of luck!
