I was working on my 'baby newt'- a 4.5" f4 OTA with a 1" secondary and just for the heck of it took the 1.25" focuser off of it so i could try a 2" 40mm eyepiece on it [TF w/ it's AF should be just under 5 deg]. It was dusk but wasn't dark enough to try it astromomically but i pointed the scope at a ridge over across town and was surprised to see a great image w/ an apparent full field illumination [of course at the range of 8 or 10 miles the plane of focus was farther out than it would be if focused at 'infinity', probably by about a couple inches from what i could tell so it still remains to be seen how it will perform on the sky. I should probably crunch the numbers w/ the newt program and see what it turns up...
