Hi all,
I am an electrical engineering student currently involved in a project aimed to create a simple GoTo azimuth mount. I don't have a lot of background in astronomy, so I am a bit confused on how to find the position of a star in the sky.
After some research on my own, I figured out that the following information is necessary (maybe not enough):
1. My location on earth
2. Time in my current time zone
3. The right ascension and declination of the star I would like to find
I was then confused by a flood of astronomy vocabularies. In order to understand the process better, I really need a concrete example.
So for example,
I am located at 40.4259° N, 86.9081° W, and I wish to find Andromeda galaxy (RA = 00h 42m 44.3s, Declination = +41° 16′ 9″, I found this data on Wikipedia) on the sky at 1:00 AM EST January 13th, 2019. Assume we have the telescope calibrated and pointed at the north pole star (I am not sure if this is enough as a reference point), how would I move the telescope to find the Andromeda galaxy then?
This might be a terrible example, I am just writing down some random numbers and time hoping it might work. If you think this example is wrong, please please provide a similar example! I really need to work through some examples to be able to understand all these! Thanks a lot in advance!
