Yes I know of Darryl's images but if you look with a high res monitor you can see a lot of speckle despite him using 4000 frames per channel. That says a lot about noise characteristics.
You might also consider pixel size in the equation too Ray. The
sensor has smaller pixels. That will lead to not only a scale difference but also smaller well depth being a lot smaller.
You can run higher frame rates but only because the scale is so much smaller. The reported frame rates of 90 fps are really only based on the scale. If you look at Darryls images and commentary (as long winded as they are) you can glean that he is imaging at 6000mm with a C14 and then he resamples quite a lot. At that scale even a flea3 would run at 90 frames per second.
My recommendation of course is always based on budget. If Neil cannot afford a flea3 then by all means buy the ASI. The same for yourself Ray. If you can afford more buy the electronics.
