Hi,
Another attempt at an RGB image, 20xRGB @ 20 seconds, not flats, worked out the main flat problems is caused by reflected light in the scope and also a slightly off center filter holder?
Anyway, this is with the 80F5, the ED80 will be in use soon.

Now I'm going to do some SII, OIII & Ha colour images.
Oops that was me
Here's a single 5 minute Ha.
