You're welcome Terry :-)
In any case, there is still enough time to get a bigger telescope and to practice the imaging of planets. The height in the sky is always a problem. The closer to the horizon the more disturbances.

Even at 45 degrees up I notice several pixels of dispersion of the Red, Green and Blue image planes as well. So I find I have to realign the color channels at the end of processing.
I have the "luck", that I have some other houses around me, so I can not so close to the horizon. Fortunately, I had no shifts between the colors until now. But I think that will be due to the short focal length and the relatively slow telescope
