Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

This beautiful and seldom imaged target was a challenge for me as it was located very low in the southern sky in an area with the smallest gap between my tree lines. About one hour of data was collected each night over four nights to produce this image.
