At risk of beating a dead horse, throwing good money after bad, or just sounding like a total ninny, I could use some input from some self styled engineers. I read a review on this forum I believe where it was suggested that though not readily interchangeable, the image through an EO Raven could be improved by using another manufacturer's eyepiece. My Raven has what I would describe as a three-flange bayonet, and I notice most others do too. The two primary concerns would be:
a) the tension on the bayonet, or in other words the length from the mating surface to the flanges, which could be altered unobtrusively (in one direction) with spacers, or possibly in the other direction by having it machined, and
b) the ability of the scope to focus with the new eyepiece, or the ability to maintain the proper distance between the objective lens and the objective end of the eyepiece (clearly I have only an elementary understanding of what the heck goes on in my scope when I look through it).
Has anyone ever tried anything like this? It is an expensive experiment, but I was considering buying something like a Kowa 32x WA eyepiece and investigating what would be needed to mate it up to my EO Raven. I also am aware that the actual magnification (and other specs) will not be that listed on the eyepiece, so maybe a zoom would be better, but I am curious about what liberties people take with their scopes.
thanks
