Re: RE: [APML] Rho Ophiuchus Region

Hi,

 I have found this region to be very challenging to get right with color film. I have tried PPF and a Tak FSQ in the past and gotten poor results. The best I have seen with color film is Tony Hallas's version.

When I switched to Tricolor with the 8" Schmidt camera, the results were significantly better. Tricolor on CCD is also very good.
