Coordinates: RA 14h 50m 0s | Dec +46° 0′ 0″

Anyone look at this void? Seeing kind of a blinking star in there.

Cool stuff, the whole area seems pitch black. Looking at it right now from my backyard in a bortle 8 zone.

I think you misunderstand the Bootes Void. The Bootes Void is a huge area of space void of galaxies, not a milky way feature such as dark nebula where the stars are masked. The stellar density for that area is quite normal. 

 

IIRC the area has only around 50 galaxies where the normal density would be in the many thousands. You can see this in Megastar or SkyTools if you plot all galaxies and create a chart at the coordinates.

I did a little hunting in the void a few years ago. I will see if I can find my notes. The only galaxy I can remember seeing was Markarian 845 a nice elongated spiral. Around 1' long by .25' wide. Not to difficult in the 25" at around 15th magnitude. The others were just little smudges barely visible.

Wow, what looks to be Barnard dark nebula or perhaps a Bok globule is used in the video to represent the Bootes Void.  That's not what it looks like at all.  How misleading!

Very much so.
