I know flip mirrors typically don't work with newtonians because of need for too much backfocus. Does anyone know if using a barlow will fix this?
flip mirror and newtonians?

I'd like to do planetary photography and I'm having trouble getting the planet in the field of view, using Celestron Neximage5 and barlow.
Now don't laugh: I'm using a 12" dob on an equatorial platform, so it's already a challenge getting things precisely aligned (very touchy), but I think I can manage that if I can just find the planet. I've read other topics where people swear by using a flip mirror, but I assume they're using SCT's.
I know people swear you can't do astrophotos on dobs, but I've seen good results.
