Bahtinov Mask Pro
Bahtinov Mask Pro is the result of many years experience printing and designing bahtinov masks. It is designed to be the very best focusing aid, while being easy to use and suited specifically to your lens or telescope.
The mask can be positioned over a lens, lens hood or telescope. Where it's positioned relative to the optics will not affect the masks performance.
Measure the outer diameter of you lens, lens hood or telescope as accurately as possible. There is no need to include tolerance as this is done by the soft felt of the mask. Also select what focal length this is for. The shorter the focal length, the finer the mask grating, however there is no benefit of using a finer grating than needed.
Using high quality 3D Printers with an extra small nozzle enables for an extra fine grating to enable better performance with wide angle lenses.
The thick internal soft felt layer will both help protect your lens or telescope from scratches, while also helping secure the mask in place. In warm or cold temperatures, where a normal mask may expand or contract, the soft felt means the mask will always be the perfect fit.
My products are 3D printed to order by me, and as a full time physics student I am often quite busy, so some items may be a little delayed depending on my schedule, most items are dispatched in 1-5 days.
The 3d printed items can be a bit delicate depending on the design, so need to be treated with care, and can occasionally very minor imperfections may be noticeable, but will not affect the item in any way. If you have any problems with an item once it arrives please let me know.
Shipping:
UK: Items are shipped Royal Mail 24, tracking will be provided and items should arrive within maximum 7 days from ordering, if item has not arrived by this time, please let me know.
Europe: Standard items are shipped with Royal Mail International Standard delivery which Royal Mail claims to arrive in 3-7 days however I find this usually takes between 1-3 weeks and has no tracking. Express delivery with tracking (usually with dpd) can be selected if desired.
Rest of world: Standard items are shipped with Royal Mail International Standard delivery which Royal Mail claims to arrive in 3-7 days however I find this usually takes between 1-4 weeks and has no tracking. Express delivery with tracking (usually with dpd or dhl express) can be selected if desired.
