Have you applied flats?.. Main issue looks like vignetting

There is quite a bit of the blue stuff in amongst the muddy red but I found it pretty hard going trying to separate the two..........difficult to tell where one begins and other ends so to speak.

Just remember to take your flats without altering the optical train. Once mastered you will see a massive improvement.

i normally use a white t-shirt over the aperture pointed at my laptop screen

For flats i usually just wait wil the next day when it's light, and simply point the sope stright up in the sky (asuming there's no clouds there), set camera in AV mode, and that's it. no t-shirt, white-box or anything like that is needed.

Though, don't remove the camera from the scope or change the focus.
