I am a relative newbie to AP and just joined astrobin today. Have a Nikon D850 and having problems getting a snap on light pollution filter for it. I did buy a "Nikon compatible" one online but it didn't fit. It looks likes it's a peculiarity of the D850 unless someone on here can say otherwise. Thanks. Andrew

Hi Andrew, welcome to the hobby and welcome to astrobin. Always good to see new faces. 

Clip-on filters have always been difficult to find for Nikon cameras. The main reasons are that Canon are more popular for ASTRO and that Nikon camera body vary. This means that filter maker would have to make a specific filter for each camera type.. So not really a good investment. I have a D5300 and I never found one for that camera. 
AS for the d850 i believe there was a filter but if I'm not mistaken Nikon modified something on the camera at some point so the clip-in filters won't fit anymore on some D850. 

Do you use telephoto lenses or a telescope?

Hi. Both. 14mm for nightscapes and a 72ED for DSOs and I live in a Bortle 5. It was the Astronomic filter that did one but after a firmware upgrade on the D850 it no longer worked. I think Kase only supply for mirrorless. Before buying a dedicated Astro camera I want to become competent with the setup I have. I have a planetary camera that so far I have only used for guiding so lunar and planets are on the menu this winter.

I live in a Bortle 7 and I spent 2 years imaging with my D5300 and telephoto lens without a filter. If you image around new moons and start your imaging sessions when the objects are above the light dome and clear from airglow, you can still image pretty easily.

When I got my refractor (still with the D5300) I purchased a 2 in multiband filter. I have the triad ultra but optlolong filters are good and cheaper. That would be the best option. And that's something you will be able to use after when you upgrade to dedicate Astro cameras.

good morning from Northern England. Unfortunately I spat my coffee onto my duvet when I googled the Triad Ultra. Can I just place the Optolong 2" filter anywhere in the train or will it affect back focus and so will need to take that into account re spacers?
