Hi Peter, loved this video and was so hopeful for finally getting to the 'stack mode' part with success. I followed everything up till 7:43 in your video. And then when I get ready to click stack mode, it's grayed out and not clickable. Do you (or anyone else reading this) know why or what I need to do in order to be able to select this and go on further? Thanks in advance for any input. :) Oh I'm using Photoshop CS5 (might be too old of a version? but why is it even there then) :)

There seems to be some older versions of CS6 that do have stacking available for smart objects. I tried this method and stacking can't be pulled up in the dropdown.

Thanks for that tutorial! The question i have is how you compensate for the earth's rotation or do you use a star tracker?

Hi. I have a question. Do I have to take a crop factor even if I use canon g7x mark ii? And is the 300 rule same as for DSLR's? Thanks.

Hey man, awesome vid and i like how it’s a pretty simple and very useful process. i do love the video, but i, unfortunately, have a 11-16 tokina on a crop body so i’m wondering: is there a way to shorten my shutter speed and still do this?
@travel9to5 5 years ago

thanks for the tutorial, but what would have helped greatly is explaining what kind of input pictures you used for the stacking.. several exposures? the pics look pretty identical...
