In this video I try out the Optolong L-eXtreme dual narrowband filter for Astrophotography using a dedicated one shot colour ("OSC") camera and give you my first impressions on its performance. I hope anyone thinking of buying this item for astrophotography finds this useful.
As with all my videos, I don't claim to be an 'authority' on the subject in question, but hope my understanding and personal experience of it are helpful to others, as other peoples have been to me. If you have any tips, suggestions or additional info, please share in the comments section.
I should also make it clear that I have no affiliation, financial or otherwise, to any of the products or vendors I may refer to.
