Focal reducer...

What does a focal reducer lens do exactly?

[Cornelius Varley]

A focal reducer like this one http://www.firstlightoptics.com/reducersflatteners/celestron-f63-focal-reducer.html effectively reduces the focal length of the telescope and therefore increases the field of view. There is also this type http://www.scopesnskies.com/prod/antares/barlow-lenses/focal-reducer/0.5x.html which screws onto the end of an eyepiece.

Quick question regarding this topic, how does the assembly works for the focal reducer using dslr?

Is it Focal reducer > Visual Back > T-adapter >T-Ring > DSLR?

And since I have a Zoom eyepiece can it be

Focal reducer > Visual Back > Zoom Eyepiece >T-Ring > DSLR?

....ok i'll push it, does it also work for Barlow?

Focal reducer > Visual Back > Barlow (5x) >T-adapter > T-Ring > DSLR?

Thanks!

Drew,

I used a focal reducer, visual back, 2X powermater then DSLR a while back, but I only shot the moon. It worked well enough though. I would assume a X5 wouldn't make any difference to the order of things, just the magnification you get.
