This was a fun target to process as it is very bright. This is a significant improvement over my prior attempt. The target is pretty low, only peaking at 35 degrees at the observatory. It makes getting sharp data quite a challenge. You have to overshoot and discard many images only holding on to the very best. This is called Image Culling. Check out the image in the Nebula section.
