Compare your own image
Drop in your stacked image of the same target. Blend or blink it against the dust map: glow that matches the dust structure is real nebulosity — smooth glow that doesn't follow it is a gradient. (Frame your image at the same field width for the cleanest comparison.)
Auto-align (plate-solve). Uses your own free astrometry.net account to recognise your image's stars and snap it onto the dust map — no manual lining-up. Get your API key from your nova profile page.
