Bahtinov Masks

[Stefan Buda]

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.

Which one would fit Photoline 115mm refractor?

[Stefan Buda]

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.

OK will do and sent by PM, thanks

Blindman measured the ID of the dew shield: 127.8

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,

[Stefan Buda]

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.
