Easy solution, but expensive, is to do what I did and buy a Denkmeier 2" Power switch Diagonal...it has both a 2x Barlow and a Focal reducer built into it... which means you do not need to buy a Barlow and you do not need to buy a focal reducer plus you have upgraded to a very good 2" diagonal ...

Then spend more money (sound familiar) and buy a couple of low power 2" eyepieces...

All of my 26 mm and lower power eyepieces are 2"
and all my under 25 mm higher power eyepieces are 1.25... BUT since I have the Denk each eyepiece gives me 3 different magnifications and 3 different FOV's ..all with the push of a lever BUT with a heck of a lot of refocusing especially if going from the Barlowed Mode of say a 20 mm eyepiece (200x) directly to the Focal reduced mode which yields 67x .. I've learned to do it in steps and go from 200x down to 100x (regular mode) then drop down to 67x...

Actually I personally do 80 percent of my viewing using lower power 26 and above) eyepieces then I do higher power...so the 8-24 zoom would not get a heck of a lot of use... I wish they had a 25-40 zoom eyepiece...
