Thought i'd at least have a go from here to see what was possible. RGB,IR and CH4 images attached. Altitude was 14-16o. The mid-seb outbreak longitude was presented.

Meade 14" LX200 GPS, efl= 6400 mm
Filters: RGBset and IRpass pro (Astronomik)
Camera: ImagingSource DMK 21AF04.AS @ 33ms (Irpass 66ms)
Seeing 5,5/10, Trans.: 3/5
Comments: I used R+Ir instead of R-Ir for R channel

More false-colour imaging using IR, with good seeing for the altitude. Surprisingly delicate detail visible in the EqZ and SEB.
These additional images from the 11th were taken at a lower focal ratio than those I sent yesterday, so as to get a sufficient intensity on the chip to image at 807nm.
Still, the experiment shows, that even about f12, the results are better from the 742nm filter. The 807 works in a range where sensitivity is not so high, and the required longer exposure length seems to more than make up for being further into the IR. In fact, the only objects for which I have found 807nm useful are Venus, the Sun and the Moon.
