This, IMO, makes all the vr stuff actually worth it. HOLY CRAP, that was cool! Equipment used:
Playstation VR headset
rechargeable battery pack
And that's it. Just hooked the X-T3 HDMI out into the box that comes with the headset, turned it on, put on the headset and... Yeah! That rocked. Used a couple of different lenses, found generally that for this set-up the best visuals happen with f/4 and faster lenses (for star observations, at least). I'm gonna go try and see what I can see 'cause Orion should be up about now, but I wanted to come inside and report back because that was really cool. I was just holding the camera, no tripod or anything. I also did a session with SharpCap -- that was neat, but the HDMI straight out of the camera is way better w.r.t. quality (at least with this particular set-up).
If nothing else, this is THE WAY to get focus with a DSLR/Mirrorless IMO. I will put in much more time on this tomorrow night, but it was really easy to see when things were in focus as the screen in the headset is very large. 10000x improvement over using the LCD on the camera.
So, to camera makers everywhere... I have a bunch of ideas on how to make this system really rock. "Clean" HDMI output is essential. Wireless HDMI transmission (a-la drones, depending on the resolution that's possible) would be very cool with a headset that could receive it. 4K resolution would be absolutely bonkers (1080p is the resolution for the Playstation VR headset). You just plug a headset into the camera, and/or use wifi and/or use some other thing, and away you go. It's fun to just pan the camera around and see what's up there. I could almost see the blue in Pleiades (I have a huge Tokina AT-X that I'm gonna try tomorrow night, as that's 300mm and f/2.8).
Anyways, more to come, but just try this. If a phone/ipod thing had HDMI input you could use the cheaper VR goggles. Next on my list is true 3D "binoculars" with two ZWO cameras, lenses, and whatever string and duct tape is required to get it to work. I think it'll be pretty darn cool once everything is hooked together (assuming I can sell stuff so I don't run out of money and/or time). I have an iexos-100... If one of these VR displays could hook up to that with ExploreStars, and you could use the controllers to move the mount, and somehow you could mix that w/the HDMI output from the camera (you can do this on a laptop, of course, but it'd be cool if it could be done with just the goggles, the mount, and a camera)...
Time to go have some more fun.
