I'm a newcomer to AAVSO and am in the process of doing the ten-star tutorial. I've sucsessfully generated charts for all of the ten stars except Mu Cephei (Hirschel's Garnet Star). When I ask for a chart with north up and east to the left, the result places Mu Cep to the for right about 2/3 of the way north in the correct position relative to other stars in the southern part of Cepheus. However, it places a target cross-hair in the center of the chart, at the wrong location for Mu Cep -- namely, about half way between Delta Cephei and Epsilon Cephei. The chart thus generated does match my star atlas (Sky Atlas 2000) insofar as it correctly places Mu Cep in the correct location in Cepheus, but does not match the atlas in terms of where the central target cross-hair is placed. What am I doing wrong? Or is the VSPlotter making an error?
Hi, Henry,
but if the star is in the 10 star tutorial, there is a chart for it in the tutorial, so why the need to generate a chart?
Charts for bright stars need to be much larger than VSP can handle.
Cheers,
Sebastian
Still, why the error I described? And if charts for bright stars need to be larger than VSP can handle, then what is the top star brightness that VSP can handle?
Thanks, Henry
Instead of Mu Cep
Hi Henry.
Instead of Mu Cep you should writte miu cep. MU Cep is another and much fainter star.
