That's what I'm finding also. Raleigh scattering is strongest for the shortest wavelengths of light. So infrared light penetrates the air as if was nonexistent.

Perfect!

We did the same geez 20+ years ago with a Live ATV flight. With a small CCD Camera that was big sensitivity in the Infrared.

We did not change anything in the camera, But we did use our rotating mirror system that use a mirror that had a special coating to reflect the infrared and longer freqs, and do whatever with the others.

The mirror sadly was just slightly not big enough so in the corners of the field of view we saw the straight out natural  view as the camera would normally see, and in the middle 90% was the off the mirror with the long only wavelengths seen.

The difference was incredible! The contrast was un describeable in the filtered image. Then at altitude, the usual in color images the Blue haze that washes out all the details, in that filtered image was stunning! the long waves penetrated that blue haze and the details seen on the ground were incredible!

Chlorophyll absorbs red and blue light for energy and reflects green and near infrared. So NIR images show healthy plants as very bright.

The color image was taken with an Apeman A60 camera set to record images every 10 seconds. The camera is like an affordable GoPro. The gray scale image is a Near infrared image taken by a Mobius ActionCam set to monochrome. It's hot mirror has been removed and visible light is blocked with a dark blue and dark red theater gels. 

The camera combination works well together. Now to see if I can use Wood's glass to block visible light but let ultraviolet light reach the imager.

Could be.  The cold after dark may have zapped the battery too.  Hopefully it'll come to life tomorrow and can us know where it landed.

Registation cost is just for the Friday conference and hydrogen.

Winery tours include lunch and you will pay that expense on your own. Three wineries cost $5 each. Parma Ridge winery, were we are eating lunch, requests we spend at least $300 total. So I need to make sure I have enough people going and purchasing lunch and bottles of wine. The cost of wine runs from about 15 to 25.
