Possible to loan me one to test it out before i consider buying one? With an extra element in the light path i still can believe it'll brighten up the image
just imagine a magnifying glass doing the sunray exeriment. it concentrates the light source from a wider field to a narrower field, so the light is now more concentrated therefore 'brighter'hommel wrote:Meng Lee wrote:ok, if a focal reducer is made dedicated for the scope, then image will be brighter (because the object is now smaller) and will not degrade the image, in fact, most dedicated reducers flatten the field and gives you a flatter view

Oops now then I post because the shipping took quite a long time.
Hommel: Visually, its essentially a smaller and brighter view with rather bad abberations at the edges. Ok, I can lend you a SCT reducer to try out.
