Hi everyone, I am continuing my run using the fast newt astrograph. I had previously imaged the Iris with the 80mm last night I thought I would take advantage of the dark sky and give it ago again. In the past I had used the L-pro with reflection nebula but I struggle to get any definition between the dark clouds and black background. I figured the L-pro was blocking to much light so last night I used only a Luminance filter. I know that light pollution and camera sensitivity makes a huge difference, but please share if you have any tips for imaging reflection nebula.
