I've got an AT60ED coming soon and want to consolidate things into a single travel case. I have a Pelican 1510 carry-on size case that's the perfect size for it, but it doesn't have any foam inside.
I think the best option for this is Kaizen foam. It's dense and can be cut precisely with a box knife. The other option is to buy a Pelican foam insert specifically for the 1510 but it's less dense and is the pre-cut cube foam that you pull apart to form the shape you want. I will be shadowing the scope, astro cam, power supply, and a star tracker mount so they are held securely inside the case.
Wondering if anyone on here has experience purpose-building a case for a scope and shadowing the foam. I got the idea from Milwaukee pack-out kits for carpenters, which use Kaizen foam.
