Unwanted reflections in night shots

I think it is shutter shock. And mirror lock up will most definitely address vibration caused by the mirror, but I doubt it will address micro vibrations caused by the combination of the shutter curtain opening and using a less than stable tripod.
It is hard to diagnose this without seeing the patient, however.

Agreed about the patient :) I know shutter shock is a concern with longer lenses with much higher focal lengths and techniques of hand placements (perfectly illustrated by Moose Peterson I believe) but I hadn't realized it would be significant with shorter and smaller focal lengths. I did have to learn that technique of hand placement as I have a heavy 8 lb. version one Canon 500F4. Mind you I have a decent 3xxxx series Gitzo with a Wimberley WH-200 & a Markins M20. I would imagine the head could also be part of the patient diagnosis :)

When a camera has a shutter shock problem it is usually between 1/25 and 1/160 sec. Moose's approach works. I use it all the time when I am on a tripod.
I had the Gitzo Series 3 with my 500 and found it inadequate. Which is why I ended up with the Feisol. Gmbals are funny. Even the crappy ones will work fine if you don't lock it down. I will never understand why people insist on locking down gimbals.

Locking down?

When photographing night scenes, I generally remove the UV filter. One also needs to keep in mind that light sources are an issue, but one with which exposure can deal. That coupled with other techniques.

Also, be sure to turn off image stabilization when shooting on a tripod.
Lenses (and even cameras with IBIS) can sometimes blur a shot because they are trying to adjust out vibration that isn't really there.

My apologies, I thought that I attached these to the original post. The first is the overall shot, the second is a crop showing the blurred or reflected lights.

Please return to your reply and store the original files so they can be downloaded and analysed in detail. These thumbnails are not enough to provide a detailed analysis.

I also use live view, zoom in and confirm focus manually and if I don't use a remote, I shoot with a two second delay.
We're headed up to the 'Burgh in a couple of weeks and look forward to taking some cityscapes.

At 1 second exposure, I see camera movement in the image, not reflections from a filter. In addition to a sturdy tripod, try either a remote shutter release or a 2-second delay when manually pressing the shutter. Set-up on solid ground and avoid your own movement after releasing the releasing the shutter until the exposure is completed.

Definitely camera movement. Definitely not reflections. Everything is blurred, not just the lights.
I would consider a combination of mirror movement, shutter shock and inadequate support. I would rent a better tripod and see if you see a difference. I think you will.

For a one second shot I would at least use the 2 or 10 second builtin timer, or cable release to avoid any shake from pushing the shutter. I'm assuming you were not in a windstorm on a Mattel tripod waving in the breeze..

Using a cable release, on a Manfrotto lightweight tripod, shooting with a Nikon D750 (or D5000) and a Tamron 24-70 lens so a different / sturdier tripod may be in order.

My sense is that it is your tripod. Are you using a remote trigger.If not becarefull you don't set up vibrations when you click the shutter. If so, redo the image without the UV filter.
Can you do a time released exposure so you are not in contact with the camera when it goes 'click'. I often use a 2 sec. delay.
