since I had servere break downs due to cold ice I just could do some lighttrack photos the old way with a Sigma Art 135mm lens, here a 3 panel mosaic, total ca. 90min at f/2.2 using a modded D800E. Missed the complete Barnard loop, next time...

This is a wonderful image. It would help me if I knew the FOV of this mosaic. I'm using APSc & have 90 & 56 & 50mm. So I'm trying to figure out if one of them would give a similar FOV as your 3x 135mm. I could do a mosaic or single frame.


thanks. sure it will. be sure to increase exp.time. I prefer longer focal length like this. less would take more time if you e.g. need to close aperture to like f/4
