Dedicated Astrophotography Cam Vs iPhone

[stargamed]

As per an earlier post - I'm having little luck getting my Orion StarShoot All-in-One Astrophotography Camera to
work. I tried another laptop reloading the camera drivers, then ascom drivers and finally ascom platform 
and then Orion AstroCap software - paying particular attention to the order. But still no luck other than scan
lines to that program and no feed at all to SharpCap. 

The thought dawned on me - might I be as well off just using my iPhone and a brace to have it look through
the eyepiece of  the telescope rather than a dedicated CMOS device in the tube? Currently I have an iPhone
6Plus. But I could upgrade it it I thought it would work as a good substitute for the StarShoot dedicated cam.
Thoughts? Setup Orion 8" refractor, Sirius EQ G mount 25mm and 7.5mm plossl eyepieces. 

If dedicated device is really the way to go - do they now speak directly to the iPhone for capture as opposed
to outputting to a laptop? It's a little clunky bringing the laptop into the field.
