My Optics are ready and are shipping! I should have them within 4 weeks. I received the final optical specs (namely spacing between the different elements) which will allow me to finalize the structure. I found that the front of the scope was a little too light so in order to avoid having to add counterweight to the front of the OTA, I had re-machined the front ring, made some changes to the CF tube ends/fittings and used thicker CF tubes. I was waiting on these final specs before I cut the tubes to length.
I am not an expert in Optical engineering, testing. I am not afraid to admit the test results below don’t talk to me too much. I will judge the quality when I start taking pictures and hopefully I will be happy!
First, here’s the Ronchi test:
Next is the Foucault test:
And here’s the data from the Foucault test:
I can’t wait for the first light – I’ve got quite a bit of work ahead of me, I need to get busy now!
