OK... Thanx Dan/Mr.P......Reflective media will not suffer from chromatic aberration... IIRC...per MG...the original stage lumia was incandescent reflected off krinkled cellophane material...so...therefore...no chromatic aberration.
.
But...if we use HID or incandescent....we will loose the interference patterns which I am accustomed to seeing with Laser Lumia.
Also...with a refraction Lumia generation method....the Chromatic aberration will be present...be they continuous or discontinuous.

PB...looking at the referenced pic above....Yes...looks white....looks kinda like Lumia...but...not what I am used to with Laser Lumia...Not sharply focused, not nebular, no interference patterns....so....I assume made with HID....via a reflective method.
.
Like I said....I want it all !!! Sharp focus, Nebular, Interference patterns and FULL SPECTRUM WHITE !!! Is that too much to ask !!!! ??? I fear the pesky Laws of Optics will rule the day !!!
.
The " Solar Prominence lll " Lumia project will employ ...Co-axial RGB propagation....which I predict will deliver some white areas...errr....maybe....but nothing fully white....sigh....stink'in Refraction caustics !!! Where is a White Laser beam....when ya need one ????
