Re: [APML] Tak Epsilon 160

Mike,

When properly collimated, the Epsilon 160 will give you great images across 
the entire 35 mm field.

The thing that I worry about with the STL1100 is the weight of the camera. 
[I had the same thoughts regarding the new large format cameras as well]  I 
hear from SBIG that it is about 5 lbs.    That's nearly double what I put 
on the E-160 with the ST-2000XM with color filter wheel.  The E-160 does 
not use the helical focuser that the E-210 and larger Epsilons use. There 
certainly is the potential that the weight of the camera will cause 
problems with focusing and the image plane.  That camera is far too 
expensive for me to take a chance with it not working.  [I'm waiting for 
someone I know to buy one that I can test on the Epsilon.] <g>

I would think that the Epsilon 210 would be a better platform for the 
larger CCD camera.  The focuser is intended to accommodate medium format 
cameras.  At 620 mm focal length, the image scale of the E-210 is very 
close to that of the E-160.

Just my $0.02 worth.
