U.S. chromacor II ?       #5560837 - 12/08/12 12:47 PM Edit   Reply   Quote Quick Reply   My first question is will the chromacor II work with a APO doublet? I'm not after colar correction as I am wanting it to correct the 1/6 wave of over correction. Then if it will work will the natural color still be visible on planets? I am using a F-7.5 instrument that is in question. Thanks Dane Post Extras:       TPMack sage Reged: 03/06/06 Loc: VA Re: chromacor II ?

You can dial in the needed spherical correction with this corrector. Post Extras:       dag55 super member Reged: 04/13/11 Loc: Hamburg, IL. U.S. Re: chromacor II ?

However, a small amount of overcorrection may not be such a bad thing to have since, as a scope cools, it will tend to show undercorrection, which the small amount of overcorrection (and it is small)will tend to compensate for.
