200p Bahtinov mask tip

[miguel87]

Just a heads up to all of the 200p users looking at making a DIY Bahtinov mask.

If you can get your hands on a celebrations plastic tub as pictured, it is almost exactly the same diameter as the 200p tube assembly and just slides nicely onto the end of the scope 😁

Obviously this will not fit. I'm sure some random product out there will fit!

where is the mask tho' ?

how did you cut it out?

[miguel87]

There are free print out sheets online with the correct sizes for almost any telescope at http://www.deepskywatch.com/Articles/make-bahtinov-mask.html

I then cut out with scissors on the printed paper, stuck that to the base of the sweet tub, spray paint to mark the holes. Removes paper and slice with stanley knife and metal ruler.

It's a nice thickness to work with as it cuts quite easy but is rigid enough to hold when finished

look forward to your results

Thanks a good idea about spraying paint.

I made one out of a cornflakes box, lasted years, until it was replaced with a laser cut one.

Need a bigger box of choccies.

As a note, I suppose anyone with the right laser could cut any size and variation of mask. I was thinking of getting a laser engraver/cutter for my business but just could not justify the cost.
