Yes, I could see the advantage to a permanent set of ersatz 2" eyepieces if I never used a filter wheel or binoviewer. But I have two filter wheels: one loaded with filters for the planets, another with filters for DSO. The planet filter-wheel sees much sky time at home - often stacked with a binoviewer!
The DSO filter-wheel is great at my dark site to see immediately the effect of different filters on bright nebulae or to switch between an empty slot and an O-III to bag planetaries. Often I've seen veteran observers spend quite a bit of time using my filter wheel to see how nebulae appear with the different DSO filters: broadband, UHC, O-III, H-Beta and an empty slot. Evidently it is a very convenient and practical gizmo that provides immediate feedback. Much better than having to screw filters on and off an eyepiece in the dark.
Hey Mike, my 5 position filter wheel came today. I picked the 1.25" version to see how I fair with this before I think about a 2 inch one.
A couple of questions
1) the screwing eye piece adapter has a single set screw to hold the eye eject In place. I'm not happy with digging screw gouges in my eye piece barrels. How do you approach problem?
2) do you have a 2 inch wheel as well? If so, when/why do you pick one or the other?
3) this Orion model is sturdy, and then fittings are tight. Would you select a different model from another vendor if you were to do again?
