Solar filters
Hi im thinking of purchasing a glass solar filter for my 6" refractor just not too sure what to get theres a few available at 165mm I.D. and the next size larger was around 180mm. The 165 mm filter will fit quite well if i was to remove the dew shield and the 180mm one would be around 10mm larger than the dew sheild. Can they be used without the dew sheild attached or could it potentially cause damage? Thanks
