Hi everybody,
This Bahtinov mask seems great!
I'm thinking of a mask for my (only visual) 24" dob.
If I keep the Bahtinov factor to 150, it leads to a very difficult to do and weak resistance mask:

So I made other simulations :
Bahtinov factor 100:

Bahtinov factor 80:

Bahtinov factor 50:

The factor 50 or 80 seems best to be both strong and easy to make but do you think it will be as efficiency as the 150 ?
I do not wan't to make several 24" mask...so long job to do!!!
Thanks in advance
Raphaël
