.. I was wrong check @reef remnant his answer

[stone lake]

Okay tysm

[reef remnant]

@stone lake you use a bhatinov mask

That is how

[stone lake]

Oh

[reef remnant]

Also if you don't have a bhatinov mask (which you probably dont) you can make a diy one by using string and making an x shape over your telescope. Kinda like this

I searched it many people also said you could do this, so you’re right

That isnt a Bahtinov mask, bahtinov masks are used entirely for focusing, and should not be used while imaging. This is a diffraction mask, to replicate the diffraction spikes a newtonian gives because of its spider vein system that holds the secondary mirror in place. Hope this helps

[reef remnant]

Thanks for the help

[crimson trail]

Great shot! What scope?

[fallow venture]

Thats not what a bahtinov mask is for and it doesn't make your stars look like that a bahtinov mask is for focusing and gives your stars 6 spikes not four

[reef remnant]

I know how a bhatinov mask works. I explained it wrong thats all.

[fallow venture]

Ok
