I'd give black felt a try on the internal sides, to act as a baffle maybe to see if that reduces the reflection the other options to build some roughness into the interior surface of the shield itself to stop light bounce and thus reflection from happening. Any 3d printed plastic will always tend to be 'shiny' as it's been melted.. the other option i just thought of though is to use a matt black spray primer.
@@StevenMorrisPhotography should have asked in the first post are your reflections always typically the same size/same place and are they there when NOT using a filter? Reason for asking, is could it be that your getting a secondary reflection from the filters? One of the star party's I went to a while ago out here on lake Tyrrell when they used to have them, a fellow astrophotographer was getting reflections and it turned out that it was the filter not being perfectly aligned/optically correct and causing a mirror like secondary reflection into the imaging sensor. If it's that.. then no amount of changes to the shield itself is likely to do much as it'll be reflecting even with light 90 degree's to the primary mirror and reflectors etc as the reflections actually in the imaging stack. Hope you work it out though, and hope you get some clear skies soon, for me *eyes the clouds* there trolling me, clear as all day and now 25-30% coverage with that light haze.
@starfleetau I did wonder that myself, whenever I changed filters between the different uv/ir cut filters I have the reflection was in the same place, the brightness of the reflection changed though. The filter that let the most light pass was the dullest while the filter that blocked the most light (l extreme f2) the reflection was a lot brighter. I’ll have to double check those findings on another clear night. I hope you get some clear skies soon!
😂 $200, I wish. You and I have spoken about the cost to have this printed via email. The quotes came back as high as $700USD for ABS. This takes a large printer and a while to print. I may just buy the aluminum one from Celestron. The files look great! Keep up the work and clear skies.
Wow what….. $700 USD really! I though you had mentioned it was around $200-$300. Hopefully someone can help here, if you want contact me via email and I’ll check which one it is you want again and I’ll see if I can get it done for you.

I use Musuo Black on the inside of my dew shield, it’s meant to absorb over 90% of light. I will look into baffles though.

It is very weird to see orion upside down 🙃
Everything is upside down here 🤣
