Right Ascension in degrees for follow-up with FLWO Tillinghast telescope HELP!

• by Gez_Quiruga

  I am looking at a star with a right Ascension given in hours, minutes, seconds for the J2000 epoch. Should I convert this into a decimal and then multiply by 15 to get the degrees or should I use the galactic Longitude? The number is 14 hours, 59 minutes and 05.0 seconds. I calculate this to be 14.984722 as a decimal and then 224.77083 degrees.

  Yes, I did it like this: 14 59 05.0 (14*15)+(59/4)+(5/240) 224.770833333 degrees (decimal) same as you

  but it's easier with this https://www.swift.psu.edu/secure/toop/convert.htm 😉 the Right Ascension of the object is greater than 120 so is Ok

  Thanks for the reply. I shall definitely use the link in future because I had a different method.

  I used 15 [(14)+(59/60)+(5/3600)]

  Ok it's the same 😃 The converter is useful if you need to sort through many objects
