DSLR full spectrum - UV/IR cut or LPS filter?

[DainiusU]

Hi everyone,

 

got a dilema here... Got EOS450D with full spectrum mod and now deciding should I get LPS filter (e.g. IDAS LPS D1) or just UV-IR blocking one? I have looked at LPS D1 and my conclusion is that it blocks UV and IR fairly well, and add some extra functionality for the periods of full moon (my imaging site is in a very low light pollution, clouds are more of an issue, so having clear sky on strong moon light is a scenario that I would rather benefit on having a setup ready for). 

Question is - will IDAS LPS D1 block enough of UV and IR with the curve given here: https://www.teleskop-express.de/shop/product_info.php/language/en/info/p1923_Hutech-IDAS-LPS-D1-Light-Pollution-CLIP-Filter-with-MFA-for-Canon-DSLR.html 

 

vs this Astronomik UV/IR blocking filter: https://www.astroshop.eu/l-rgb-filters/astronomik-filters-luminanz-l-2-eos-clip-uv-ir-blocking-filter/p,49263

 

I am very new to all this deep sky imaging, so trying to rely on SGL expert help in these costly decisions  

 

Thanks!
