This could be a fun scope and very versatile with 3 focal lengths:

In one setup it has a 44mm corrected imaging circle with 96% illumination.
That means it should handle even an SBIG STL11 which is awesome.
Even though its only 60mm I wouldn't underestimate it. You've got fluorite in the objective. I have seen some spectacular wide field images through this scope in the past. With the Aussie dollar above the US it makes it good value. Its the 3X the price of the Astrotech though. The Astrotech is a lot for your money. I have an Astrotech 66ED for my guidescope. A great little scope, everything works. Not Tak quality but a cut above others.
