IC-5070, The Pelican Nebula, In Cygnus
September 12, 2013 at 9:34 am
I finally processed the data I collected at the LAS Observatory (in Curby, Indiana) early Saturday morning. Wow, this was a very difficult one. It's the best I've been able to do with this dataset. It isn't the best I've seen by a long shot, but it is better than I expected considering the transparency of the sky there last weekend:

Awesome, how do you account for the rotation of the earth with such long exposure time.

God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.

I'm glad I'm not as stupid as you are!

What accounts for the red, Oro?

Blood of Christ, spilled so that you may be saved. I guess.
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.

Wish I had some nice stuff like that lol. Is this your field or your hobby or is it both if so you are privileged indeed.

I'm a board member of the Louisville Astronomical Society. I am also disabled. So while I am an amateur, I don't do much of anything else these days.
