Hi Alex, welcome to the forum.
I'm no expert, but he's my 2 cents worth.
1. Your scope is likely to be an F5. I don't think you will really need a visual paracorr. If it was faster say F4.7 lower it might be worth checking out.
2. Invest in premium eyepeices. Better to have only a few (literally) good/high quality eyepieces than a multitude of average eyepieces.
You will need to let us on a few things:
1. do you wear glasses ? Eye relief maybe a factor in your choices.
2. what do you like seeing planetary/lunar, DSO, nebulas? All above and some?
3. Do you have a budget in mind.
I've got a set of GSO eyepeices thru' a prize and compared to my 2 premiums, they don't compare at all.
I've only got a 24mm Panoptic and a 10mm Pentax XW - great eyepieces and I wouldn't trade them in at all.
I am planning to get maybe 2 more to complete the line up and its a toss up between the 17mm Ethos or Nagler, possibly 20mm Ethos or - not sure as yet.
My recommendation is to go to a astro meeting or viewing session and check some out before purchasing.
Good Luck.
Norm
