BTW, I returned Rocolax UVIR-cut filter to seller, they promised to send me back the correct one (hopefully they will perform some tests to ensure that... ).

Hi Bojan,
Nice comparison of the with and without LP filter.
I did something similar with a didymium filter on Orion and have been meaning to post the image as part of my quest to reduce the effect of LP. Your thread has reminded me to do so, so I will soon. If you'd also like to try these filters in your fight against LP, since you're in Melb, let me know. I may have one in a size that you could borrow.
Best
JA
