Vignette royal (IR 1μm)

Again, nothing special, ..initial experimentation. My target diameter for IR filters is 77mm, this one is 86mm though, I have plenty of step-up rings and luckily the front of the 72mm and 77mm Nikon Type 1 Polar is 86mm as well, so I have 2 hoods (HN-29, HN-13) ready to go, a medium and a deep one. On the Tamron, the short one works for 18-24mm (better than nothing, cause it seems that this wavelength flares a lot), but of course not for the ultra wide end; it creates this vignette, which is kinda neat. Btw., the speck in the left corner is the moon 🌔 .. came out rather prominent.

 

I cropped and centered the photo, but I was surprised how NOT aligned the lens projection on the sensor is..?! What? 😲
