My experience with Kowa Highlander Prominar (2 Viewers)

Well-known member
Good evening from Italy, with some delay I finished the English subtitles for my video about the Kowa Highlander. I have described my impressions after years of use, talking about the merits, shortcomings and the various observational areas in which I have used it. I hope you are willing to waste about 20 minutes. A warm greeting to all
Piergiovanni

Greetings, Piergiovanni. Thank you for this. I've been waiting for a review by an expert of a recently made instrument of this model with comments on its optical quality compared with the current best alternatives.

Could you please clarify the following comments on chromatic aberration? Thanks!

Text after choosing the 'English' option at the top of the page:

In focus and in the center of the field, it is noticeable, a very slight green halo on the silhouettes of airliners or birds of prey and of the full moon when the image is not perfectly focused is practically non-existent. When the image is in focus, I've never been able to notice any chromatic residue in the center of the field.
