FPV means "First Person Video" and is used for video transmission from personal drones.

 

I've been trying to figure out how to go totally wireless with astro video astronomy.  Orion has the WiFi RS232 devices for control, but wireless video seems to lacking options.  I stumbled onto the new 5.8gig FPV 7" tablets used for drones.  Seems the price is very low, but not sure about the video quality.  Would this work with acceptable quality for astro video?

 

You can see many on ebay if you search for "5.8G FPV Monitor". 

A 5.8gig wireless video transmitter and FPV 7" tablet with built in receiver are as little as $150.

The transmitter takes composite video input and so can be used with any astro video camera.

 

Is this the best solution?  Is anybody using these for astronomy?  Is there a better WiFi solution at this price?

 

Ideally it would be great if there were a  WiFi box that transmitted several video and control (rs232) channels, but have found none.

hi, i use an ordinary inexpensive wireless video sender, it works well. there are lots of them on ebay. i did a test with the sender vs a cord and there was only slight degradation with the $39 video sender. i am not sure how far away you will be, some transmit a few hundred feet.

Over the years, people tried on various forms of wireless video transmitters. About 10 out of 10, the cheaper ones be a 2.4 or 5.8GHz type, require an operator's license from FCC.
In another word, these are not gold mines.

Low power ones may be "below the radar". High power ones (marketed as long distance) are bad idea.

I like the idea of having a receiver built into a 7" tablet, but they are paired with high powered transmitters for drones that require a license.  

Perhaps that tablet could be paired with a low powered 25mw 5.8g "video sender" transmitter guyinthesky mentioned?

They are not "tablets" as people would have called. They are 7" LCD monitors with built in AM wide band receiver(s).

Clear Skies!
