M97 - The Owl Nebula revisited
The Owl Nebula - again.
After I failed so miserably last year, I was really looking forward to getting back to this one. So after almost five (!) months of clouds and bad conditions, I got my chance last night.
This time, I hit the focus quite well. The conditions were good although it was a bit windy. The cold weather (39°F) made the stars wobble quite a bit so they look a bit bloated out in the image, but that is normal and there is not much to do about it.
The equipment has not changed very much. I used a luminance foil to get decent flatfield images and I tried a new software for processing. An important change was the usage of the CLS-filter. I am much more pleased with the result. Then again it has to be said, that it was pretty easy to beat my last try.
The data of the object itself have not changed and you might want to look it up and compare the images by clicking here.
