Let me also say Welcome! I do not own this system, so I am giving you feedback on what I read.
When I read the description, I was interested in hearing about the "object catalog". It's embedded in the last paragraph and in the specifications text towards the end. It reads:
"The map is concise, but completed with Messier/NGC /Herschel catalogue, double and binary stars, comets and small bodies, and magnitude 9.5 stars (110,000 stars)"
My question is, can this be upgraded or added-to with downloading? Perhaps I missed something in the description- others can let me know. I'm hesitant because while this sounds like a lot, it is a very basic catalog. As a beginner's skills grow and as you seek to view beyond the Messiers (and even NGCs), this is somewhat limited.
The rest of it appears intriguing. When I read the description, it is in somewhat broken English and that's fine - I do wonder how communication with tech support would go if you encounter problems based only on what I read, and again, I didn't read much past the text description so I might have missed something.
After watching the linked videos, I'd add that you'd want some sort of night mode for the light from the phone, maybe there was an option for this? Or you can purchase some red film to cover the display light. At a dark site, that will inhibit your night vision.
