C14 baader 145mm D-erf - PST First test

Post by dcnikon »

Both shots using the ASI120mm - Focal length 4000mm - unmodded stage 2 pst module - so with all lenses intact. Baader 160mm D-erf at 145mm due to a temporary filtercell.

I can see a sweet spot, that turns into a ring when I tune or detune the PST.

Uber closeups!

The sweet spot you describe is normal with a pst etalon... Big field angles in the setup you describe on that etalon, so only to be expected...

Yes Mark. I am happy with the prototype. And now hope to start soon experimenting with a lens in front of the pst to alter the cone of rays. I may need a better camera than the asi120mm. Seeing and transparancy were not great. But the 30 percent good frames show promise.

Thanks!
Dirk
