Description

My first attempt at this target. The core of this one is one of the most difficult objects that I have tried to image. The core is impossibly bright and so easy to blow it out. I do need to be some more Ha but overall, not too bad. The image is heavily cropped and this target pushed my Explore Scientific ED127 Carbon Fiber to it's limits. Trying to resolve the core had lead me to one conclusion...I need more focal length.
