Those are good photos for using a phone and binoculars !
Does your partners camera have removable/interchangeable lenses?
If you did buy a cheap DSLR/Mirrorless camera (personally I'd also recommend Canon, but that's because it's what I use), then look into geting a lens mount adaptor for any old film camera lenses you may have, or look for lenses at charity shops/eBay/flea markets.
It's a very cosy effective way to get into the hobby, it takes a little bit of practice for getting used to adjusting the settings/focus etc, but nothing too difficult. And old lenses can give some beautiful effects on the images; Japanese lenses are near identical, old soviet lenses give a beautiful patena.
Another final point to consider is Mirrorless cameras are so much lighter than older DSLRs, to the extent that I carry my camera so much more after buying a Mirrorless than I ever did with a DSLR, OTOH if it's just for setting up somewhere birdwatching, weight shouldn't matter so much.
You can also get lens mount adaptors to fit onto telescope/microscope eye pieces
I'm gonna be frank with you friend, it sounds like you're experiencing something close to a manic episode.
When was the last time you ate/drank water and slept?
Have you recently consumed any drugs/substances which may have brought on this feeling?
How long have you been feeling like this?
Do you have someone you can communicate the way you're feeling to in person that can go with you to get checked out if needs be?
Changes in the psyche such as feeling oneself is God or Jesus is normally a sign that you want to get something checked out, you're probably right that if there is a God they would be incomprehensible/ineffable, which also means that you're probably not God.
Don't worry this is almost certainly not your new permanent state; it's likely that your neurochemistry has gone a little bit out of wack and you probably need some rest possibly to see a doctor as they can help work out what's going on.
The most useful phrase I have found for coping with any difficulties with how I'm feeling, both in terms of mood and when having a difficult time after taking a psychedelic is:
"This too shall pass", it's a useful phrase for bringing you up when you feel down, and to keep your ego in check when you feel like your on top of the world.
