Thank you Marc and Justin for your kind comments.
A coma corrector is very high on my list to get. Once I have my Orion G3 Monochrome camera and lots of filters, it will be next.
Hopefully the camera and filters will arrive this week!
Justin, fyi, I am using a Skywatcher 8" f5 scope mounted on the HEQ5 Pro mount. Guided with a Logitech C950 webcam through PHD.
I got another 3 hours of data last night. Hopefully tonight will be cloud free in Brisbane again!
