Hi

 

recently i am thinking to buy a light pollution filter (given i am in heavy light polluted city)

i am using nikon d5600 to shot with different lens, and want to buy a clip in filter., but seems not much choice i have..

 

should i buy normal sized light pollution filter or are there any clip in filter suggest? since i have limited budget and want to use wise from it.

 

my next goal is to start taking deep sky object.

 

Thanks

That's right, there isn't much choice.  I put a Hutech filter into my D5500, and that worked fine on the Orion Nebula at my Bortle 8 site; but that very bright target was the only one that gave credible results.

Better to buy a relatively short telescope and put a narrow band filter like the L-Extreme into a filter drawer in front of your camera.  You could increase the filter bandwidth depending on your light pollution level.

If you decide to sell the filter later, a conventional round type would have more buyers than one specialized for your camera.

Don't try to use a field flattener because you won't have enough back focus distance for a DSLR and filter drawer together.
