Video Collimation using an Aline, iPhone and iPad

Well I have finally tracked down an iPhone/iPAD app that lets me superimpose collimation rings and supports focusing/exposure/etc.. of the iPhone camera from the iPad!

https://apps.apple.com/us/app/remote-camera-control-via-air/id6470156115

It allow me to import an png file (attached) on the iPad to superimpose the collimation rings on the image.  

Wow I am impressed with myself ðŸ™‚  The app costs $3 for ability to overlay a image on the camera image and digital zoom.  The only issue I has was moving the camera around to align the draw tube with the large ring -- but the app supports the ability to adjust focus, so that allowed me to sharpen up the draw tube edge for that then refocus on the mirror center  After that it was all gravy! Might need another small tweak (see last image) But does show the pupil of the aline inside the mirror donut, inside the aline reflection, inside the secondary, inside the mirror, aligned perfectly with the 3 mirror clips ðŸ™‚

here's a sequence of photos testing a Beta version of the  with the ability  to move the overlay to align it with the mirrors and even lock the overlay to the image to zoom both together.  File names are numbered in order.  The ability to zoom way in really helps in examining the collimation.  Just needs one more tweak and Beta will become prime on the Apple app store ðŸ™‚

I've added the overlay and another one (concentric rings) to my website.  Free to download and use here.
