Primary mirror aperture mask

[PeterBolt]

I've just fitted this mask to my primary mirror...I am hoping it will improve my star shape.  Does anyone else use one?

I didn't even know they existed. I hope it sorts your problems out.

The 130pds is notorious for flaring round the stars lots of people fit one to that scope,I myself will be fitting one to my 130pds very soon as I’ve just ordered from the same company obviously the 130pds version

Just to let you know that I had to buy slightly longer screws (m4x25) otherwise the clips were pinching the mirror.

The mask was delivered in about 4 days and I didn't have to pay any import tax 😃

Not often you can say that about astro gear. 😁

I already have a ton of stainless m4 screws of various lengths ready for the job 👍

if it does a good job I may order one to fit to my skywatcher 10 inch f4 Newtonian

Good luck!  Just need some clear skies now 😂

I'm interested to see how it works out. My Bresser is pretty good now I shortened the focuser, reducing some of the asymteric flares would be a nice tweak.

It works by blocking the very edge of the primary mirror from the turned down edge that causes light to scatter causing flaring on brighter stars
