Protik,

I am not a fan of trying to get big fields in longer focal length scopes. That is what rich field refractors are for!

So make your longest F.L. eyepiece under 30mm. I recommend a 26 Nagler or 27 panoptic. That will give you a field of over 1 degree in the bigger scope and just less than 2 degrees in the smaller. In addition your exit pupil stays under 7mm which is ideal.
Then go for an eyepiece giving magnification of around 100X -120X, so Here the 13mm Nagler or 14mm Delos is the go. (I like the Delos range, better than naglers or ethos in my view)
Then for higher magnification (forget 800X) a 6mm Delos or 7mm Nagler will give 257X or 300X with the big scope or 171X or 200X with the smaller. With a barlow double all these last figures and you have those huge magnifications you may dream about but never use.
