RE: [APML] (OT) IC1396 CCD with Schmidt-like FOV

What little color fringing is visible only at relatively high powers, and on
very bright objects. For prime focus astrophotography, this is really a non
issue IMHO.

Yes you are right, but the only Taks I've seen that are true apos are
the FCT-150 and the FSQ 106.I've looked through FC-60's, FS-78's, 102,
and 128's and i still se alittle color fringing. Roland does have an
alternative, if there is a field flattener available for it- the old
version of the Stowaway.
