Long story, but because of vision problems I am moving to exclusive screen based EAA operation. As I only have one useful eye ( macular degeneration in the other), and the useful one is not great, I am moving away from reflector type designs, which require collimation (hence my recent sale of my f5 Newt and my CC8). So i need some help with identifying a suitable wide field refractor, that can be used for EAA (screen based display).
This will be observatory based, on my CGX mount (So weight is not a big concern), but speed is a factor in EAA, so f5 -6 maybe, and reducer setups would be ok, even though flat field is not that important. I am not fussed about perfect colour rendition, so an ED type would be fine. Please don't point me at TAKs.
Looking for reasonable optics, bigger the better I guess in terms of aperture, Doublet is preferred for ease of handling.
If you have a suggestion let me know here. Thanks.
