[APML] IC1396 CCD with Schmidt-like FOV

["Robert Gendler" <robgendler@worldnet.att.net>]

Hi all,
Using Nikon 180mm and 300mm lenses and the ST10
I've created a widefield color image of the IC1396 complex.
The inner detail of the nebula was imaged with the 300mm lens
(using HA and red as luminance) and the outer portion was taken
with the 180mm giving the generous FOV (straight RGB). I believe
the FOV and detail compare favorably with schmidt camera and
medium format film images of this object which demonstrates
that large field color imaging can be done successfully with CCD
and camera lenses. The widefield image is at

A cropped higher res version is at

The lenses were mounted on the ST10 using Steve Mandels adaptor
and were secured on the mount using two losmandy adjustable tube rings.
The 150mm ring fit perfectly around the ST10 while the 125mm ring 
supported the lenses. I have two pictures of the setup at
