Apple iphone XS Max - PhoneSkope Adaptor (1 Viewer)

I need to upgrade my iphone....... is anyone using the dedicated PhoneSkope adaptor for the Apple iphone XS Max (6.5" screen) please? I like the idea of the big screen, but is this too heavy to stay on the scope tightly? Or should I go with iphone XS (5.8" screen) please?

My scope is a Swarosvski ATS 65mm HD Telescope with 25-50xW zoom eyepiece.

I currently have an iphone 6 with Kowa adaptor, which has never really fitted properly and now broken.

Thanks

I have a phonescope adaptor but for a leica scope. Its a snug fit. Doesn't move when put onto scope eyepiece. But use mine with an LG phone. Should be ok with a bigger iPhone I reckon.

I've used two PhoneSkope set-ups. The first was with a Motorola G3, which is quite a large phone. I 'lost' this (although it turned out to be temporary) and replaced it with a used Samsung S4 Mini. Both are interfacing with a Swaro 65 / Kowa 883, as the eyepieces are very close in size.
The Moto was a little harder to use; on the 65mm on a CF tripod, the additional weight meant the pan/tilt had to be made firm prior to fitting. The Samsung is a lot easier to deal with, and put in a pocket.
However, i think the major consideration is the phone's display; if you get a nice, bright image out of what you've got, i'd use that. I've often fired off shots in bright daylight not knowing if i'm on target or not. I'm now carrying a cloth i can throw over the phone and my head to shut out the light, like some frock-coated Victorian portrait artist..... Putting the PhoneSkope on the eyepiece (being a tight fit) is most likely going to move your trajectory a little anyway.
Due to my 'loss' experience, i now carry either phone in a secure pouch on my belt.
