Hi All
Interested in getting my 10" dobsonian mirror resurfaced due to etching.
I found the following
Spectrum Coatings in US for US$155 (R 98%)
OWL in US for US$176 (R 97%)
OrionOptics UK for £102 (R not specified)
AstroOptical Aust for $295 (R not specified)
Had a look at postage and Aust post is $85 to US and $119 to UK.
So has anybody used the US services and have opinions about them vs local and UK? Is it worth getting the higher reflective coatings as the gent from Sirus Optics near me said it is worth it. I also found on Google an Isaac at Chi Qin in Sydney but I assume he will be about the same price at around $300 or so.
Any guidance would be appreciated.
cheers
Dave
