The electronic dry cabinet arrived, sad to say, even after removing the legs, the window was still blocked, but it's not a big issue.
All of my telescopes, eyepieces, filters, optical stuff, camera lens and cameras could be packed inside, and there are still some space left.
What are left? The mounts, and various adapters, etc. They don't have to be stored in humidity controlled environment, so maybe I can just buy a box to place them along with the dry cabinet. This dry cabinet occupies half of my windows platform.
