You don't need the IR filter immediately, if at all.. I haven't seen any side by side direct comparisons of IR filter vs no IR filter.. I know my images aren't any better with the IR filter.. but it might be better on some targets (eg: mars + the moon) than on others (eg: jupiter + saturn). The jury is still out for me.
So for now, you only need to spend $145+$45+$10 (postage) and you're up and running. K3cddtools will work with the celestron neximage the same as with the native toucam, that's just for capture.
Registax (bundled with neximage) will be used the same in both.
If you can get the neximage for $265 (how much for postage?) that's a pretty good price.. as long as the 1.25" adapter is threaded for filters.
