Hi Stefan,

What is the largest diameter you can cut? I'm interested in one for a 130mm refractor, the dew shield is 180mm in diameter.

I'm also in the market for masks for an 85mm camera lens and an FS-60 (like H). I've had other masks cut for these optics, but the slits are far too wide to make effective spikes. Your fine slits look like they'll do a much better job.
