Astrophotography Imaging of the Orion Nebula from city skies with my RASA 8 telescope and ZWO ASI1600MM Pro! You don't need dark skies to get an image of M42, the Orion Nebula. From light polluted skies, you just need plenty of integration time.
In this video I collect enough data to get a great start on a project of imaging the Orion Nebula from Chicago in broadband RGB.
I also cover some of the light pollution issues in my location from streetlights. I also spot some geosynchronous satellites (not Starlink) as the images come in.

Photographs of the universe, with galaxies, stars, nebulae, supernovas, comets, planets, Moon, Sun. Inspiring wonder about the night sky, even from the light pollution of Chicago.

Thanks for watching everyone! What is your favorite winter target for Astrophotography?

Since three years we have a lot of clouds in the winter. So all targets are welcome :)

Not only light pollution but led lamps and snow on top to reflect. Now there's a challenge. Data looks great 👍

Very nice image! You continue to amaze with what you are able to do with a Bortle 9 sky. I promise I'll stop complaining about my Bortle 6 skies.

Thanks Ron! Yes they are, though once the leaves are back the direct light at least is blocked pretty effectively.

Nice video; I am enjoying your channel. I'm glad you talked about the geosynchronous satellites. I've seen these also when imaging the Orion area. But their motion does not seem to be completely explained by the motion of the earth, as I think some (not all) of these satellites have non-zero orbit inclinations that make them move in their apparent altitude (above the horizon) as well. That's why not all of those tracks are parallel on the Witch Head. Thoughts? You've made me want to re-process my Witch Head data from last year and see if I can see those too!

@WindyCityAstrophotography 2 жыл бұрын

Thanks so much, glad you are enjoying it! Yes, I think you're right, and the north/south oscillation is shown in the "vertical" displacement from parallel. I'm curious at some point to do an untracked shot of this region or similar. Star trails galore, but some well-defined points showing the GEO satellites, and then I presume a few very short trails at an angle different from the RA drift showing those slightly-inclined orbits.

Does a tracker stay on target when using a long exposure/shutter time?

@WindyCityAstrophotography 2 жыл бұрын

Do you mean a tracker like the Sky Watcher Star Adventurer? Yes those can do long-exposures, over a minute from what I understand if the polar alignment and balance is good. With my computerized mount and autoguiding I routinely do 2-minute exposures and don't lose any frames to bad tracking. I have gone longer at times with no issue, and have heard of others going 5 minutes or longer with my type of mount. I am only shooting at 400mm, so pretty forgiving on tracking.
