So what do you image during full moon? Well if you have tight narrow band filters you can image nebulosity or you can just have a crack at doing short subs on a favourite globular cluster. That does come with its own issues like very extreme gradients, but it was fun all the same.

A massive 44 minutes of data went into this image. Luminance subs were 2 minutes and colour was 60 seconds; with core subs being 20 seconds each.

There are still issues with either the secondary cage or actual secondary moving just very tiny amounts, but I can get enough data to construct images. My suspicion is that the actual secondary is rotating a little and that it is being caused from the spider not having enough stiffness. Further stiffening needs to be installed onto the secondary cage in the form of diagonal braces, which will eliminate the cage being the cause of the star movement.
