About the DayStar Combo Quark H-Alpha Eyepiece - Prominence Model... 

The Combo Quark offers a choice for the SCT and long focal length user.   Designed for SCT, Maksutov Cassegrain and refractor owners with focal ratios between f/15 and f/30.    An innovative all in one design combines the needed adapters, snouts and DayStar H-alpha filter into a simple and compact assembly.    Simply insert the Quark into your diagonal, pair with a ERF (energy rejection filter), add an eyepiece and view.     The compact design of the Quark allows you to view the sun in full hydrogen alpha glory without the weight and expensive components associated with more traditional systems.  

The Chromosphere model is designed specifically to enhance edge detail.  See solar flares in gorgeous natural color and intense detail. 

The ERF is sold separately and is neccessary for safe viewing through a SCT or Mak-Cass telescope. This specialized filter reduces heat built up in the optical tube keeping your eyes and telescope safe.   Specifically SCT owners must use a front mounted off-axis ERF to reduce their aperture. Maksutov owners operating at f/15 natively do not need to reduce the aperture of their telescope with an off-axis filter but do still need to employ a front mount ERF to keep heat from accumulating.

Product Questions

I noticed that this for f/15 and higher. I h e a 8 inch f/10 SCT Celestron. Would this work on it? Would the lower f-stop interfere with the photography?
