Forschungssatellit ERNST: Erfolgreicher Start im Orbit

Im August startete der erste Fraunhofer-Kleinsatellit. Er soll Raketenstarts detektieren. Nun sind sämtliche Funktionen getestet und alle Systeme freigegeben.

The Escape (2018);

OK, done my homework, and seems I didn't post this panorama on here before, so here you go.
This is an infrared panorama, done indoors. I've used the Kodak infrared filter (I think Wratten 87B, not sure), and I suppose it has a threshold of about ~800nm or ~850nm. Luckily for me, I do keep some old light bulbs (tungsten), and I do keep them for such projects. The whole house is lit by LED lights which do not produce infrared; thus, I've replaced the bulb just above the scene with a tungsten one (100W or 150W). The black areas in the panorama, behind the door and on the sides, are actually areas that are lit by LED lights, but they turned black, of course, because they don't give out any IR. Who would have imagined that old light bulbs like these would be at some point in time be considered as a treasure trove?

SWR AktuellSOFIA-Institut: Was hat die Flugzeug-Sternwarte gebracht?Wie entstehen Sterne und wo endet unser Sonnensystem? Das sind einige Fragen bei der Erforschung des Weltraums, die unsere irdischen Probleme doch eher klein aussehen lassen. Um Antworten auf diese existentiellen Fragen zu bekommen, war das mobile Teleskop SOFIA im Auftrag der Wissenschaft unterwegs. Das war in einer speziell dafür umgebauten Boeing 747 untergebracht, sozusagen als fliegende Sternwarte in der Luft. Warum dieses Projekt, das jetzt zu Ende ist, so wichtig war, hat mein Kollege Andreas Böhnisch mit Professor Alfred Krabbe besprochen. Er ist Leiter des SOFIA Instituts an der Uni Stuttgart.

Anyone here can help me?
On my IR fullspectrum converted Fuji X-E3 I am using a TTArtisan AF 27mm f2.8 XF lense. When I cover the lense, looking on the screen or the viewfinder I see this flare (?) when I focus to infinite. Now changing the focus the flare gets less visible the more the focus goes to the near. Somewhere at half a meter its gone.
The lens is clean and clear - same goes for the sensor. I cannot see that flare with any other of my lenses.
What could that be? Any ideas? Would appreciate if you share this post or point me to someone who might be able to help.

Still playing with and getting to know my full spectrum converted X-E3.
#Berlin, Charlottenburg. Sky was quite gray with spots of blue. I am not sure if I did too much processing in darktable. After all the picture does not look like autumn at all.

Again I forgot to take notes about settings and filters and so.

Lens was a TTArtisan AF 27mm F2.8, Filter was 630 nm I believe. Here's a light vignetting which might be a result of the stepup ring needed to use my 52mm filter on the 39mm mount of the lens? Or the lens might not be fully infrared compatible? I cannot see a hotspot in the center of the image.

Infrared picture of a park with lots of trees and gras and blue sky. The Trees and gras are very light - almost white due to the channel swapping processing .
