Just took delivery of a TV 8mm Radian
Very good high contrast views.
Yes the FOV is not so wide & means more pushing with the Dob, but should be good in the LX-90.
Found it particully good at resolving the Homunculous nebula in Eta Carina.
More detail due to the high contrast compared to my 7mm Seibert optics.
Almost no internal reflections on Jupiter & able to resolve surface details well.
