Feedback on Intane Achromatic 203mm F/6

Hi Alice,
Thank you for checking back.
We had a very busy week and I am just now getting caught up on emails.
The lense was extremely well packed, the custom cut foam held the lenses securely, and the heavy wall box was still in good shape after shipping.
One of our professional opticians was impressed with the surface finish of the glass and uniform coating.
I was delighted to see the interferogram included with the lense. I did some additional testing with a Rochi screen, and I would say it agrees with the lenses rating

It was nice to not see any obvious zones, indicating good glass homogenaity.
I am looking forward to doing some star testing of the lense this weekend, and expect to see some very good images.

Sincerely,

David
