Leo I應該是本星系群中離銀河系最遠的衛星星系, 距離我們約82萬光年. 比大小麥哲倫星系遠4-5倍.

在背景中也可以見到十幾個離我們遠很多的PGC星系.

Master Subaru,

How do you label the objects on the image? Can you show me how?

Master Subaru,

How do you label the objects on the image? Can you show me how?

I use Pixinsight's scripts:
1. Script > Image Analysis > Image Solver, enter imaging scale to obtain the position of the field of view
2. Script > Render > AnnotateImage, to label the objects by list

They are indeed very interesting and powerful functions.

Master Subaru,

How do you determine the Pixel Size and Model Parameters?
