Stu Posted May 22, 2022 Share Posted May 22, 2022 Excellent images @neil phillips! It’s an amazing AR, took me a bit by surprise when I viewed it today. I haven’t managed to observe for a while and wasn’t expecting anything so big. The separation in the umbra on the left hand side was really vivid I thought. Anyway, amazing detail! Thanks for posting these. Link to comment Share on other sites More sharing options...

I redid my bresser out of thinner denser cardboard. Vinyl wrapped on one side. The 190mm film is still on thick spongey cardboard. Not ideal i dont think Link to comment Share on other sites More sharing options...
Pete Presland Posted May 24, 2022 Share Posted May 24, 2022 I made the 1st one out of two pieces of cardboard, taped together with the film in-between. The aperture was a poorly cut 190mm approx. I was messing around with it at work, when a colleague ask me what i was up to? Long story short he has cut two pieces of hardboard with a perfect round aperture of 200mm. So i have been spraying them white tonight, in preparation for the film. Hopefully the white colour will stop too much warm of the filter surround. I will post a thread on here for definite showing the filter and hopefully the a decent 1st light. Link to comment Share on other sites More sharing options...

Sounds good will look out for the post Pete. Will be interesting to see if you think it has improved performance. I seem to have this gut feeling the thick spongey cardboard will once heat up. Transmit more heat back down the tube. Though in my case i made it quite thick (3 layers) So i am uncertain if being as thick as it is. It can actually get through that much. I am unsure ? But thermally your hardwood must be a good solution Link to comment Share on other sites More sharing options...

But thermally your hardwood must be a good solution I think the white colour must be a good thing as well, one thing is for certain i think, the seeing needs to be very good for it to perform well at that aperture 1 Link to comment Share on other sites More sharing options...
