Description

This is a comparison of NGC7331 taken at the Milwaukee Astronomical Society.

The wide field image was taken to confirm the integrity of the AP900 mount using my personal 5-inch f/5 Stellarvue Refractor. This testing is to support a proposal for MAS to purchase a refractor scope and take advantage of a currently unused roll-off observatory as well as an AP900 mount.

The narrow field image was taken concurrently using MAS's C14 Edge w/ 0.7x reducer (f7.7) on an AP1600 mount. This too is a test image as this setup is still being tweaked for optimal performance. This image is a stack of 5x30min Luminance subs taken with an STT-8300.

Bortle 8 skies.
