Description

This was a "first light" image using my new 10 Micron GM1000 HPS. I was keen to test if its unguided capabilities could allow me to shoot at 10 minutes plus. This image of Comet Lemmon is using 8 minutes sub frames at ISO 800. The good news is it worked. I got nice round stars and no frames were dropped!

The comet is approx mag 10 on this date.

A full tutorial for the processing method is presented here
