An experimental image of M81 and M82 taken with a 10" F10 Meade SCT, Celestron f6.3 R/C,
my custom 2" visual back and a Lumicon NEG. This image represents the maximum possible field
achievable with the R/C in a given OTA as there is absolutely no vignetting in the image other than the
R/C itself and the SLR T-Adapter. 75 minutes with Ekatachrome 1600.
