It's been a long time coming. I 3d printed a mask ring to cover the objective lens tabs and the pattern has gone. Just need some good weather 🫤

This is the view looking back down the telescope. I'll see if I can 3d print a mask at work. If it doesn't work then I'll get rid and buy something different, it's just very obvious in something like this, which is why I didn't bother continuing with taking subs. Thanks all.

Thanks for the reply. It's very clear all the way down. Just these tiny tabs at the front.

Hi, can anyone please advise me how to go about reducing/removing this repetitive streaking in bright stars? It's the same pattern every time. Skywatcher Evostar 100ED Pro with 0.85x Focal Reducer. ZWO ASI294MC Pro. I believe that I have the correct amount of back-focus (55mm). Could it be the silver screws on the face of the camera reflecting somehow off the reducer? The ZWO website shows black screws. Thanks for any advice. Sorry for the blurry photo.
