Hi all, this is my first attempt at imaging with the 14" at F10. I have only used F6.3 with the field flattener/reducer up till now, because I thought that would give a flattener FOV than F10. The field flattener/reducer would always have some of the FOV out of focus. This image at F10 was fully in focus, only with coma around the edges that a SCT is known for. I would be interested to know if others have had similar unsatisfactory results with the Meade F6.3 field flattener/reducer?
This planetary is in Musca, magnitude 13 and diameter of 1.3' . It has a very unique internal structure. This image is from 4 minute exposures at ISO 3200 and 10 minute exposures at ISO 1250, with Astro 40D. The image is only slightly cropped as I had to do a meridian flip during the run.
The image is 1.1meg
