This years version of M45. It is much better than previous attempts. I really have trouble with lrgb inthe RED/WHITE zone. This is also first light with the SV70T. It came with a paper saying it has a .992 Strehl. I like the wide field view it shows with the QSI6120.

There was a .8 reducer/ff used

Anyway thanks for looking and I love to hear comments.

Thanks Rick
