Hello Adrian,
Recently in his forum I posed an image of he Eight burst nebula and I called it NGC3132.. it is only a very slightly cropped image.
This image was acquired at a focal length of 2464 mm and a QHY8l on shot colour camera. It is a stack of 20 225 second shots.The processing was with APP with the appropriate dark, flats and flatdarks. The integration Was just using defaults.
I think you need at least four times the exposure you have and don’t worry about your focal length
so, keep up the good work
Chris
