whipdry Posted December 1, 2021 Share Posted December 1, 2021 I'm looking for an explanation of what's giong on here, one morning after an imaging session I noticed a spider web pattern on my stainless steel counterweigh... see first picture. This is the creepy bit! days later it can still be seen... see second picture. Seriously whats going on here? Peter Link to comment Share on other sites More sharing options...
900SL Posted December 1, 2021 Share Posted December 1, 2021 Guessing here but a spiders web is acidic so it may have etched the surface layer of the stainless steel Link to comment Share on other sites More sharing options...
AstroKeith Posted December 1, 2021 Share Posted December 1, 2021 Very pretty! Looks like at some time a web got caught on the counterweight. Web is sticky by nature's design, and leaves a residue. Dew formation is very much affected by surface contamination - dirty optics dew up way before clean ones. Link to comment Share on other sites More sharing options...
whipdry Posted December 1, 2021 Author Share Posted December 1, 2021 Thanks for the replies... after speaking with a person working for a UK etching company it seems a possibility that a combination of spiders web & contaminated moister, possibly salt due to my location can effect some grades of stainless-steel!
