The only plans to sell the spike-a mask in Australia is by shipping from the US. Info can be found on the web www.spike-a.com |
Jerry, i have a few questions:-
- according to the formulae the grid pattern widths change with the focal lengths of the scope - the product you seem to be selling does not look as though you can take that into account but rather have to accept a predetermined grid width that you have setup for manufacturing - IE with the 10" Meade it is 13mm, but for my R200SS vixen f4 it is 5mm grid spacings? Your web site has no options for choosing a grid sizing - just the outer diameter of the grid mask?
