Kudos on the the job you did with what you had to work with… As stated earlier, Astrophotography can be very challenging. I kind of miss being able to do it anymore (NOT staying up all night at sub-freezing temperatures, however ;)
Luckily I live in an area of california that never ever gets to sub freezing. As a rule the temp never gets below 25% and even then it’s rare. So star gazing is a relatively comfortable hobby.
I did the same thing for the Solar eclipse we had tow (?) years ago. I just never reduced it to 2 minute or so video. I still have the footage though.
