Bespoke Bahtinov Mask Manufacturer in UK

[peroni]

Hey all,

My local Astro club are looking at doing some astrophotography with their long focal length reflector.

Tracking challenges aside, achieving good focus is paramount.

Does anyone know of a manufacturer / suppler in the UK who can make a bahtinov mask to the telescope specifications?

Perfect. Thanks nightfisher. I'll pass the good news to the club :-D

I would create a Bahtinov mask using this generator, http://astrojargon.net/maskgen.aspx. Then I would call around locally to find a shop that laser cuts acrylic sheet material. I'd ask them if they can cut from a PDF file. They should. It will be a lot cheaper than going through an Astro specific business and it will be local.
