I’m glad you got it working. Thanks for the update!

Finally got it working. Want to know what I did wrong? I forgot to pop the transparency back up to 100% >.< Thank you for all the help guys!

Not sure if it falls into the "astronomy" category, but this was taken with my GoPro Hero4  I caught a falling star, so I hope that counts

@DM1 that's very well explained. Thank you! I shall give it a go.

I'm on iPad (which handles masks a little differently to desktop) but the technique in your video sample can be reproduced easily enough (6.00 min mark). Open main image (washer (or clock in my example). Place second image (mountains and road). Second image layer is above main image layer. Lower opacity of second image and move it/size it to get road in opening of main image. When happy, restore opacity to 100%.
Add a mask layer to the second image (the one you want to show through). Select the mask layer, go to channels and invert the mask layer. This makes it black to block out (mask) the image. Now you see only the main image.
Use selection tool and elliptical marquee tool to draw over the main image where you want the second image to show through. Copy this selection to new layer and fill this selection with white (white unmasks), now drag this new white circle layer onto the 'mask' layer associated with the second image. This creates a white circle on your black mask. The portion of the back image revealed by the white circle shows through on the front image. This is what occurs at the 6:00min mark of your video. (Actually same concept as the video I referred you to).
To finish the effect select a paintbrush and white colour then paint into the mask layer to reveal the road coming through the opening.
You can reduce the opacity of the white circle to show a little of the clock face as in my example.
Add another background (ocean wave). Mask the bits you want to see as white. 2nd image.
 

Hi, I'm fairly new to photo editing and I just bought AP. I'm trying to achieve this effect by following this (PS) tutorial, tho I'm stuck at what hes does at 6:00 into the clip. When I'm trying to make the mask and then invert it, tho I don't get the same effect in AP. Could anyone explain how to achieve this in AP? Couldn't find any AP tutorial on a similar effect.
