Description

Phew...Finally, its over. Combining images from different telescopes and cameres is never easy but this one nearly broke me.

This image was made by combining Ha and O3 light frames from two different imaging setups. Images from both setups had a lot of stacking artifacts, my framing was very different and we had different rotation. This made combining a nightmare. And on top of that I had some trouble with DEC tracking which elongated my stars. I tried my best to fix them, but you can see some elongation in this image.
