Description

Filtre ERF S-Serie 1,25 ″ pour Chromosphère


/! \ Attention this filter should not be used without full opening filter /! \

Filter of the Player One series using a high -quality optical glass substrate and multi -layer composite coating technology, which has excellent optical performance in astrophotography.

1.25 inch ERF filter (energy rejection filter for chromosphere)


This filter is an assistant filter, made for the Chromosphere Quark (HA version version), reject part of the energy and thus extend the lifespan of your quark.



Why add an ERF to Quark?


The first filter on the quark is quite small, the solar disc could be greater than it, the light will heat it as well as its support. With this 1.25 ″ ERF filter, we can protect both the high temperature filter and the filter holder.

And don't worry about ERF itself, it uses the transparent glass B270 and the multi-monte coating, it will reflect most of the energy.



Does this have another use?

Yes, this ERF filter can also be used in lunar imagery, it will provide an even more brilliant image than the IR685 filter, could also improve vision.
