Nebula Photography
Nebula Photography

Nebula photography is a wide range of exposures because they vary In brightness quite a bit.  They offer what I feel is the best color in astrophotography and why it is my favorite. Generally, this kind of photography will require the main telescope, a guide telescope, imaging collecting software, and automation of some kind.  I used ACP for automation which connects to MaximDL and FocusMax.   ACP moves the telescope to the object, center it, take the exposures, and focus the telescope as needed.    

Capturing the images

I usually use exposures of 300 seconds to 600 seconds and take anywhere from 30 minutes to 3 hours of imaging time.  Nebula is mostly in hydrogen-alpha do very well using a black & white camera with a hydrogen-alpha filter.   The color cameras have the advantage of just taking one set of images.  Some cameras that require color filters also need to take a set of images for each filter.   One advantage of using a black and white camera with filters is the quantum efficiency is much better than a color camera.

Post Processing

 I used a software package called PixInsight to calibrate the images, align, and stack the images.  Then use PixInsight for some post processing once a final image is created, however, I do most of my work on Lightroom Classic, Photoshop, and Photoshop plug-in.   Nebulae because they vary so much can be one of the more difficult objects to post process, however, they make the most beautiful photo of any of the objects out there.

Finally, my brethren, rejoice in the Lord. For me to write the same things to you is not tedious, but for you it is safe.  Philippians 3:1
