Please help me. Is the distance quoted from side to side of the given frame, or is it some other parameter?

This deep Chandra Observatory x-ray image spans about 300,000 light-years across the galaxy cluster core.

I read this as the distance shown between the two sides of the image.

The core is nly 300,000 light years

Can some one tell me what is the overall distance across.

Must be several million light years.

Have a look at this
