Addressing real things for a moment, that's a lovely image. Are you professional or is this a hobby? And, I'm curious, too: how did you account for the planet's rotation?
I'm a professional geologist, but an amateur astronomer.
I use a german equatorial mount with digital setting circles built into a go to controller, and fine guide using an autoguide camera and autoguide telescope. Think of the mount as a very expensive, high precision clock. It syncronizes the telescope's movements with the rotation of the Earth.
To minimize instrument error, I take five minute exposures, which are then stacked to get the total of two hours total exposure used in this image.

The red color is ionized hydrogen gas (hydrogen alpha emission). The hydrogen is ionized by the charged particles emitted by the embedded stars.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
