10-14mm would be too small for most open and globular clusters and a lot of nebula wouldn't it?

My most used is the 14mm pentax which does great for all but the very big dso's. If I want a closer look ill put in the 10.5mm
to look at a small plantetary neb. The 14mm has a FOV equivalent to a 20mm plossl.

What focal length do you use for the planets mostly? I'm guessing around 6-7mm?
What would you recommend as a good premium eyepiece in that range?

For planets I barlow the 14mm, an if the seeing is really good, I can barlow the 10.5mm . Incidently my barlow works at 2.2x with my eyepieces measured by star drift time tests.
You could go for a pentax xl second hand, an XW new or a televue nagler t4 12mm, or maybe a 9 or 13mm nag t6.
The pick of the bunch would be the 12nagt4, except it doesnt work well with my barlow.
