235mm ERF in stock at Airylab

Post by fjabet » Tue May 23, 2017 5:01 pm

Hello guys,

I have produce 3 pieces of 235mm Dielectric ERF filter for C9.25 or large refractor. They are fully dielectric IBS hard coated. One is sold, so there are two units left.
Those ERF are 100% made in Europe (France and Italy). They are better than L/8 PTV in transmission, and have a transmission on the Ha ray (656.28nm) better than 90%.
They come with a spectrophotometer and wavefront analyser report.
 
We can deliver also in addition an HaT telecentric amplifier, and a custom aluminium heavy cell to transform your C9.25 (preferably a EdgeHD version) in a 9" HaT.
 
Another small run of 3 units is scheduled later this year, but probably after the eclipse.
You can contact me at info *at* airylab.com
