I've tried an experiment this time,to see if I could get any cloud detail using an simple Wratten light-blue filter (80A),since I don't have an UV filter.
It seems that the experiment was a success,and thus I'll use it from now on until I can get my hands on a better filter. This could also be useful for any other observers that don't have a specialized Venus filter and can get a much cheaper Wratten filter.
All details are on image,but I'll also post them in the e-mail:
