Description

Ha data from this summer and December are combined with OIII data from December. I should probably try to dim HIP 379, the very bright star in the center of the field. Silly, but I appreciate the star as I used it for focusing checks in between runs as the temperature changed, meaning I didn't need to stop guiding, slew away to a bright star and slew back to restart guiding. In the next month or so I will switch to a carbon fiber OTA scope for a while; this one has an Optec TCF. The combination should reduce focusing/temperature adjustments to a minimum.
