Bahtinov Masks
I still have a bunch of various sizes up to about 145mm diameter.
These all locate on the inner diameter of whatever at the front of the scope.
So, you need to measure the locating diameter to be able to get the right size.
All 3D printed ABS.
Prices are between $15 and $25, plus postage (of your choice).

Can you do a tri-bahtinov mask for a 12in Meade ?

Hi Glenn,
Yes, I could, but it would be too expensive because I would have to print it in many pieces and then fuse the pieces together with acetone.
A size like that should be laser cut.

Sorry, human, I don't know.
You need a ruler to measure the inner diameter of the dew shield.
Though, a cheap digital caliper would produce a more accurate measurement.

Hi Stefan,
I'd like to purchase one for my SkyWatcher Equinox 120ED. I really like your design and this it would compliment the telescope very nicely!
I've performed some measurements to assist:
Dew Shield Outside Perimeter: ~ 146mm
Dew Shield Inside Perimeter: ~138mm
Kindly let me know how to proceed or if you prefer me taking additional measurements.
I'm located in Melbourne.
Many thanks,

Hi Chris,
The closest size I have is for 139mm ID, but I can print one with a scaling factor to match your 138 ID. Price is $22 without postage.
Send me a PM if you wish to proceed.
