Greg, at f/5.5 the longest useful eyepiece is around 30mm and a few come to mind that have decent eye relief without paying the Televue Tax - there’s an ES 70 degree 30mm, and APM have an ultra wide 30mm

To that I’d add another around 15-20mm ... explore the APM site for ideas.
If you want real budget ones there are GSOs from Andrewscom.com.au
