Hi all,

As always at the X-mas time we offer our new full aperture two bands
Dielectric Energy Rejection Filters (DERF) for largest amateur solar
telescopes. We produce these filters for 8", 9", 10" and 11" SCT and
other type telescopes.
With our DERF filters you can see and study the nearest star - our Sun
with resolution and details never reachable for amateurs before.

These filters allow you to see or to image our Sun in two bands:
1. Hydrogen alfa H-a at 656,3nm
2. In both Calzium K and H lines (393,4nm and 396,9nm).


Our solutions for solar narrow band imaging allow to work with the simplest and the
cheapest etalons and filters available on today's market. And the results
are just amazing. Now everbody can obtain such amazing results with
the equipment affordable for most amateur astronomers.


All filters are sold out.



Below is C11 telescope pictured with the ARIES 295mm DERF filter on it during imaging session.
Also attached several images taken with this telescope during 2017.
