Hi All,

I need to understand how to track the star with Dosbsonian telescope Mount?

First I need to write some information:

Let say:

My observing site Latitude (Singapore) = 1' 19" 48" deg and longtitude = 103'48"49" deg


I am observing the star located at Altitude = 45 deg and Azimuth = 150 deg

Observing local Time: 10.45pm

Find out:

1: Altitude deg movement per minute Rate

2: Azimuth deg movement per minute Rate

So Now, What will be the Altitude and Azimuth movement deg per minute rate? Is there any formula for this to calculate so I can write into the software?

Please show me how you calculated.

Best regards

Mitoo

As a minimum you need to take into account the date too.  

Personally I would cheat and download this software…

...after setting up your location you could simply set it to follow system time and note the changes off screen…Why re-invent the wheel?

To calculate it to any degree of accuracy the equations are all readily available on the www - all you have to google it… but I warn you, they involve a lot of variables!

Theory is when you know everything and nothing is working. Organization is when nothing is working and everyone knows why. Practice is when everything is working and no one knows why.
