So, I made a homemade clineometer using a protractor, straw, string, and a weight (in my case I used a nut that had no threads). Using this device I measured the height of a door, and the height of my rain gutters using some basic trigonometry. All you need is this device and a way to measure how far away from the object you are standing.
This is my first math video, and I hope to do more in the near future. I figured a video like this may come in handy for others. I may take this device and use it to measure a few more objects, and maybe even the height and width of a tree. If anyone has any suggestions of math videos I'd also appreciate the ideas. Thanks for watching.

Early this morning, August 5, around 1230am EDT the clouds cleared and I was able to get my first ever image of Mars. It is the closest to earth that it'll be until 2287. Unfortunately there is also a dust storm happening on Mars during this opposition.

Two images of Saturn last night, August 4 at around 1030-1100pm EDT. Both images taken with my celestron 8" SCT and my Canon T3i with video crop mode. The first image was at 10x with no cropping in post processing. The second image was at 3x with cropping done in post processing. Seems that you definitely get a sharper image at a lower magnification, but still get roughly the same size image after a crop. Still learning and playing around with planetary imaging. I'm quite pleased with my results from last night. Now I have some Mars data to play with, too.

Which method for my math videos do you prefer; using my old Samsung note 4, or using my whiteboard notebook?
Examples:
Whiteboard notebook - https://t.co/A2BMQhBfv4
Note 4 - https://t.co/IXxRnh3cAv
Both have their pros and cons as far as recording and editing go.

Given that I have no experience, how difficult would it be to create an equation on a website that requires 5 inputs from the user in order to generate a result?
The user needs to see the results. It's a calculation for imaging stars with a camera and lens on a tripod. The results let you know how much star trailing you'll get based on your inputs. I still have to run a few trial runs of the equation along with actual images taken, but if it works I'd like to make it available for someone to input the fields needed to calculate how much star trailing they'd get.

My best Saturn image to date from early morning of June 12, 2018. Hope to get better data in the near flute with hopefully more stable skies. In fairness I didn't even expect it to come out this good since the video I took was very dark. http://adirondackastro.blogspot.com/2018/06/saturn-june-12-2018.html?m=1

I did another edit of my M57 data from June 11, 2018. More information on my blog: http://adirondackastro.blogspot.com/2018/06/m57-june-11-2018.html?m=1
