UFO Sighting in St, Croix, New Brunswick on 2017-07-23 23:06:00 - Very very white crescent shaped object flew over me.

I was taking some photos of the milky way. and had just set up my camera and had taken a few shots, at f3.5 25 sec. at 2500. i had live view on and just tuned to my right and when i did i saw this huge white object overhead. it was very very white, but did not hurt the eyes. it was the whitest thing i have every seen. i was shocked for a few seconds, then i tried to get my camera off the tripod. i couldn't see to change the settings, and it was almost gone, so i switched my camera to movie mode and took a series of single shots. it disappeared and after a few minutes i put my camera back on the tripod and took a few more shots of the stars and the milky way. when i processed the files the next day, i found that it was also in one of the milky way shots. it looks vertical in all the shots i took, but when i saw it, it was horizontal. crescent shaped and had a very small tail(?) in the centre. i don't know what else to call it. but it was just notable not very large. because i had a small lens on and it was almost gone, i didn't get any really good shots, but if they are enlarged you can see it, and it is better in the milky way shot even if it is farther away. i was disappointed that i didn't get a closeup, but i was pleased to see it. i have raw files of the photos. if you would like i can email jpeg of them. if you want the raw files i can send them some other way. they are too big for internet. when i saw the photos i went on line to see where to send them. i found national ufo and sent them there. i thought it was the same as mufon. sorry about that. i have cropped them all except the one with the milky way my exif files show the time as 10.06. but this was a mistake as i didn't reset my time after a vacation. it was 11:06 pm
