Re: [APML] Comparison of small Sagittarius cloud in 2 Schmidt Cameras

Excellent shots Richard!
    You must be very happy with how the 9" is working. Focus is good,
vignetting doesn't appear to exist and exposure times so short you could
manually guide! Did you ever add up the total construction time of the
Schmidt? What I am really looking forward to are the multi-hour exposures
using large format tech-pan through a W92 filter. :-)

Hi, here  is a comparison of the small Sagittarius cloud in my  Celestron

and  also the same region shot simultaneously with my 9" Schmidt which was
posted last week.
