NP101 and the Big Barlow, will it work?

I would like to have a longer focal length scope for some objects. I am currently using the NP101 non-is model and am wondering if I could use my "Big Barlow" with this scope for imaging with my ST2000xm. I think I can achieve focus, but have not tried to do so. But I am wondering if anyone has ever tried this?

This is the reason why we end up with more than one scope! It's the golf club analogy!

Give it a go and let us know!

There is also the Baader fluorite flatfield converter.

Of course when you barlow you also increase your F ratio for the same aperture.

This means longer exposure time (I think).
101 aperture at F10 if you 2X would mean 2X exposure time to get the same brightness. If you wanted shorter exposure time you would need larger aperture for the same F ratio.
