I have a Tripp hard suitcase that would make a good travel case for a scope. I made one for my Celestron 8″ SCT some time ago, using some furniture foam. The approx. sizes are 64 x 43 x 26 cm.
A hard scope case costs about £500. Mine cost about £45 plus a £20 suitcase I had lying around (and so didn’t cost me anything)
If anyone wants it (free of charge), let me know. I can also help with cutting the foam etc. if needed. I’m going to throw it away if no one wants it. It’s just taking up space here
