Filters for planets-any recommendations.
Well with all this planet activity,the roof has been rolled off the observatory this week,and I have had the best viewing ever in my life of Mars-the detail I have been able to see through my 4 inch Vixen refrator and a Naglar type VI 3.5 mm eye piece has been quite amazing.Also used a 7 mm and 6 mm eye piece this week as well.
But what about filters for planets?? is this a good idea? if so which ones and where to buy?? I have not bought any astro gear for years,so not familiar with shops and retail outlets anymore.
I did read a thread on filter recommendations for filters,but that seemed more for nebula viewing,So thought I'd ask - thanks for any pointers.
