Hi Paul,
Unfortunately, as you know this is a really poor morning apparition for Northern hemisphere imagers of Venus coming after the excellent evening apparition in February. I think all the decent images are going probably going to come from Wesley and Miles, who seem to be having a very good run. Having said that, the day after that image was taken I believe they were cloud affected
Bright streaks are commonly seen in night-side images taken with large aperture scopes in good condition but this is one of brightest that has been imaged and the fact there is a bright spot within the streak makes it particularly intruiging.
For anyone interested in imaging the night-side of Venus there is a disucssion forum which exists to promote the imaging of Venus and the night-side in particular at: https://groups.io/g/VenusImaging
