Awesome combination !

I agree there are a few gaps in focal lengths - like 6 ... 9mm - regardless of which ones you look at.

What I found with my scope - mk91, f/13 - on the planets there’s a real sweet spot in the range 9-14mm depending on how bright it is, and hence I’ve now ended up with 7(SSW), 9 (SLV) 10(SSW) 12 (SLV), 14(SSW) and 15(SLV) so i can choose the optimum magnification. Field of view is pretty much irrelevant except for the 14SSW which is my favourite for galaxies.

This however depends on focal ratio... SCT owners have the same challenge in the range 7...10mm, and fast Newtonians 3...7mm

But looking at that lot I should have bought a 8-24 zoom.
