Compact cameras and the lens

[Journeyman]

Good day, I would like to buy a point & shoot, not too expensive, pocket size compact camera. The reason is related to a deteriorating spine issue and I want to make it possible to continue photography.

My query is about the general function. They seem to offer good zoom + digital zoom.
Wide range of ISO and apertures. View finders are missing. There are Sony and Canon products available for a round $500.00 or so. Reaching the upper end of my budget, ($1K).

What I would like is a standby birding camera, something with enough zoom to attach to a moon tracking unit. Basic non auto functions Manual, Shutter and Aperture that allow for adjustment. I am aware of the Sony range, an RX100 possibility.

Perhaps someone with experience or use of this style of camera could offer knowledge related to the cameras.

My areas of interest are - birds, swamps and lunar. The lunar could be overcome with a telescope.

Thank you and regards, Journeyman
