Hi David,

This is really interesting! One function you might consider for image analysis projects like these is MorphologicalComponents, which will let you take your binarized image and extract all kinds of measurements from those points of interest. I think that you'll find it very fun to play with!

Thanks for the tip @Arben K ! I will check it out on some of the photos from my most recent shoot

Awesome; excited to see how it turns out! (I should also add that ComponentMeasurements is what you'll be wanting to look at explicitly...)

Hey I've been told that my published notebook can't be downloaded due to size.

If you want original-size photos and full notebook try this OneDrive link (you should be able to open in browser without needing an app or sign-in):

I had to use really low quality pics to get this under the 20MB file size limit. Check out full size pics here: https://www.wolframcloud.com/env/ameneyro/Published/andromeda-writeup-v2.nb
