Saturday night provided about 2 hours of reasonably clear skies. Here
are four images taken during that time through the new NP101 (focal
length 540 mm). The setup consisted of the NP101 mounted on an AP1200.
Camera used was the Orion StarShoot Pro one-shot color (3040x2024
pixels). The NP101 focuser was used for coarse focusing, with fine focus
reached with a MoonLite stepper motor focuser controlled by the FocusMax
program. All subexposures were 5 minutes and were unguided. FOV is 2.5
degrees by 1.6 degrees, with 2.95 arcsec/pixel. North is up in all
images.

galaxy Leo I and ngc 3153, a mag 12.8 spiral galaxy.
