The Power of Stacking Images
This was taken on an entry level DSLR with a 10 mp CCD sensor. Which is far from a great camera by today's standards.
The lens used was a very old kit lens from my old Pentax ME-F a 35mm 1.7
I was basically testing the lens performance at imaging stars, the night was not very good for astrophotography either, there was poor visibility and periodic clouds.
In the near future I will be doing another "stacking" of images with a bit longer (80mm) focal length using just my dslr, a regular lens, and a tripod. I will make another post with the resulting image to show the power of stacking even more.
Exposure - 15 seconds
Iso - 800
Lens - f 2.8
2 second delay timer to minimize shake
I took 5 images and stacked them using a free program called Deep Sky Stacker
and did some further processing in Photoshop.
I've also labelled the more known stars and some areas that contain some of the better known deep space objects. You can even see (faintly) the Orion nebula.
This image is several images stacked around the Orion Nebula, Running Man Nebula, and The Horsehead and Flame Nebluas. The more images that you stack the more information will be in the stacked image.
