Get where you're coming from but I see it the other way. That old Hubble shot looks rough next to what we get now, sure, but the blur is kind of the point for me. Nobody had ever pointed a scope at nothing for ten days before, and the fact that they got anything at all out of that gamble is the wild part. My backyard rig pulls in sharper detail on a single galaxy than Hubble did on thousands back then, and still none of it feels as heavy as that first fuzzy picture.

What happens when one of those regulars needs to move their slot at the last minute? You have a hole in a prime spot that a walk in could have grabbed if you had not locked it down six weeks back. The trick some shops use is booking regulars on a rolling basis instead of a fixed block, so the chair never sits empty but you are not promising the same four hours over and over. Do you take a deposit or have any kind of no show rule for those slots, or does everyone just show up because they know you? I would worry that the regulars start treating those hours like a lease they own and get bent out of shape when you need one back.
