I only have one low power (35mm Panoptic) and a medium power (19mm Panoptic) then I get into a whole collection of moderate to high power lenses 9-4mm as I spend lots of time on luna and planetary observing and at these lengths each mm makes a huge difference to the magnification which is limited by the seeing so I can get the most out of the conditions.
While I have a good apo barlow it spends most of its time in the eyepiece box but is handy to have.
Cheers
