This past Monday night we had superb seeing here in northern Illinois. Even though it was hazy and the full Moon was high in the sky, I thought I would try imaging this tiny planetary through all that murk. I managed a personal best in resolution of 1.5 arc sec FWHM at F11 and 1.3 FWHM at F22. Normally around here it is tough to get better than 2 arc sec.
The wide field image was taken at F11 with my 10" F14.6 Mak-Cass, ST10XE, color filter wheel, on AP 1200 mount. The closeup in the upper right corner was taken with a Barlow at F22. The image is half size in order to fit mostly on the computer screen.
