First (proper) Light of 167 mm /f7.3 AP OTA
« on: 2017 March 27 14:37:15 »
After a long impasse of about 2 years, I am back in action with a new OTA, designed and built by Roland Christen of Astro-Physics. It is a 167mm aperture, oiled triplet, with a fluorite middle element, the blank of which came from Zeiss Jena's facility in East Germany and made it to the hands of Roland during the reunification. This is the same source of cristal used in the APQ series. Hence, I named the OTA AP167 FLZ in reference to this interesting back story.

I got delivery of it a few months ago, but only last Friday I had the chance to try it from a relatively dark site, close to Buenos Aires, hence the (proper) qualifier in this post subject title.

The object of choice was Leo's Triplet, which is kind of low from my location but still a great target to test the optics. Its is 2hrs 20 min integration with a cooled canon 6D. No need to say I am thrilled with this very fine instrument!

Muuchas gracias, Iñaki. Por algún motivo, el link apuntaba a una versión anterior (con inferior procesado). Ahora lo corregí.

saludos
Ignacio
