Thanks John, Leon.

The front mounted etalons give excellent full-field illumination in H-alpha, hence no "hot spots" that are common with full disk images
produced by many back-end filtered instruments.

The camera is also a rare bird...a 1" CCD with a 16 bit DA converter. Beautifully clean output with nil pattern noise. Sadly no longer available....everything is CMOS theses days
