If you plan to shoot an emission nebula with an OSC and a narrowband filter is the recommendation to polar align without the filter in place and then add it once aligned and you go to your target? I'd like to shoot the Lagoon Nebula and this is my equipment for this session:
RedCat 61
AM5N
ASIAir2600 MC Pro
ASIAir Plus
ASI 120mm Guide cam
ZWO 30mm F/4 MiniScope
Optolong L-Quad Enhance filter
