Canon 500d

[bottletopburly]

I have a canon 500d which has a mark (dent/chip) on the anti aliasing filter I could have the Baader filter mod which would solve issue in that this would be removed and still use for daytime or I could get replacement filter is it worth the mod I was thinking of getting mod and selling my modded 1000d , Juan can fix for £74 or Baader mod for £134 what’s the thoughts on this is it worth it , main Astro dslr is Nikon d5300 stock .
