Lots of Bahtinov masks

Over the last few years I designed many masks for telephoto lenses and refractors that were needed by various people. Every time I had a request for a mask, I printed an extra one or two in case I get a repeat request and so I ended up with a box full of masks. They range from 55 to 145 mm locating diameter. All are designed to locate on the inside diameter of the dew shield or lens hood, or filter thread.

If you have a need for a mask in this ball park, then send me your measurement and I'll let you know if I have one that fits.

The smaller ones you can have for $15 including postage, the larger ones are $25 including postage.

Daniel,

If you can't source one over the next couple of months, contact me again and I may be able to help because by then I will have a CNC router that should be able to cut diameters of up to 310mm.

Hi Richard,

I have a number of designs to fit various refractors from 60 to 127 aperture, but you need to measure the inner diameter of the dew shield so that I can pick something that will fit nicely.

My printer limits the diameter to just below 6" but in a month or so my new CNC router should be ready and with that I will be able to go up to 310mm diameter.

Adding to this that I'd be very keen for one for my SkyWatcher 190mm Mak-Newt once your new CNC is up and running.
