What is this I've captured?

[Brushman]

I'm starting out learning to take nightscapes and I was testing out my new camera and lens tonight...

There's a lot wrong here...no post-editing, I was testing exposure times and I butchered the raw files into jpeg so I could quickly upload - But, have I managed to capture something interesting here? Or is this some kind of artifact? 

Nikon D5300 on a tripod
Samyang 16mm prime lens
Iso 800, F2
Single frame at 20sec exposure
(Bortle 6 sky with lots of streetlights around)

Unless there is a comet passing, then it certainly looks as if you may have captured a small meteor. Then again, it is characteristic of a comet, a meteor burning up would look much brighter.

Looks like a comet... check if it's documented.. you might have a comet named after you...

Hi @Brushman, have a look at this list of currently visible comets and see if any of them tally with where you observed yours...

I uploaded your cropped image to nova astrometry and it solved this:

Using stellarium i looked for V Cas and zoomed in and it showed that c/2017 T2 PANSTARRS  seems to be around that area.

I was using Sky Safari to try and solve this myself and it said that PANSTARRS was much higher in Cassiopeia - is Sky Safari not as accurate with comets or something?

I'm sorry, It looks correct, i misplaced it "near" the wrong star. It was nearer Segin (  ε cas).
