In this gallery I have selected observations that illustrate what is possible in terms resolving detail and/or going deep using very short exposures. The new incredibly sensitive CMOS based sensors enable a truly live observing experience using stacking and very short exposures. The image literally builds right before your eyes.
All images are live stacks at the scope (no post processing) of very short sub exposures, typically 1-15s, with SharpCap using the ASI290MM on my 8" XLT Celestron SCT from my Bortle Red/White Backyard.

Sketching at the eyepiece with a variety of scopes
Live stacks using less than 60s sub exposures taken with a wide variety of cameras over the years including the ASI224MC, ASI385MC, ASI294MC Pro and the Atik Infinity. Sub exposure time for the CMOS based cameras tends to be tyically less than 15s, sometimes 30s.
