Hi all,

I've been very quiet so far since this group seems mostly focussed on planetary astrophotography instead of deep sky, but if anyone is interested, a few of my images with my 11" Edge are here: although some are also with my Nexstar 11" (all in the family).

Anyway, a bit of a strange question perhaps but I have a Celestron reducer for my personal 11" Edge and we are setting up a public observatory with a 14" Edge (and 16" Meade). I wanted to set up the scope tonight and try it out - but as yet we don't have a reducer for the 14".

So my question is: does anyone have any idea if the 11" reducer would work on the 14" as a temporary solution? They both talk about the same reduction compression and the same back focus - identical specs in fact - and as far as I can see, the telescope backs have the same threads. In the images at the Celestron site, they look suspiciously similar and they are the same price.

I have other reducers that work equally well on various aperture telescopes but the 11" reducer does say specifically 11" on the side so perhaps the optics inside are different?

I'm not looking to do any super astrophotography tonight, just get to focus, do some drift alignment and take some quick shots of the comet (making f/11 less desirable due to FOV) - so some coma at the edges is less important if a difference in the 11"/14" messes that up a bit.

Thanks!
Lynn
