Delta picked up a few ex-LATAM Airbus A350-900s as part of that airlines restructuring during the downturn in the airline business caused by the pandemic.  They went initially in to storage and then have been progressively moved to Singapore for updating to the Delta configuration.  Seattle has been the location for them to come through on their way to Asia.  I have missed a few but one was due to come through when I could see it.  Sadly, it departed a little late from Victorville and was showing due in after dark.

Since it was an unusual movement, I figured it was still worth the effort.  I would use the 500mm since it has a wider aperture and test the low light capabilities of the camera to the full.  It still meant some very low shutter speeds but I let the tech compensate for my low skill levels.  I was pleasantly surprised by how well some of them came out given the lack of light.  Since this shoot, I did also reprocess with PureRAW3 and this improved the quality of the shot further.
