About this image

Feeling inspired by JWST and its infrared view of the Cosmos

I decided to give it a go on BA142 and BA143 using my only infrared pass filter - an 850nm IR pass

The Dark Nebula is obviously less pronounced and the "E" is not so recognisable but the "Box" is still obvious

The Stars inside the Dark Nebula are more pronouned in IR and overall I'm pleased with how this turned out

I never tried IR imaging before this and it was interesting to see how much less noise was visible in the initial stack compared to other filers and shooting under a moon and in Bortle 8 was in my opinion easier as it was only seeing near infrared

All in all a fun experiment that turned out ok
