The most noticeable difference between my NP101is and FC100d is depth of focus due to the focal ratio's and the FC is a little more contrasty I think (need to get them side by side on Jupiter again).
An NP127 is a lot pricier than a TS triplet though.
Here's an interesting review: http://doctordreviews.com/4inch-shootout.html |
Thanks for that. I thought about a TV NP127i but to be honest I have not seen any spectacular images using that scope. Good ones but not top notch.
I suspect the correction is not as good as it needs to be these days to stand out. If China is putting out respectable air spaced FPL53 triplets for 1/3rd the APM LZOS price then the playing field has changed. Air spaced triplets were only done by TMB/LZOS up to a few years ago.
We also now have FPL 55 glass making its appearance. I am not sure how much better it is over FPL53, I suspect only a little.
