| Notes/ Conditions |
Conditions- After doing a few PEC runs, I decided to take advantage of the break in clouds. Conditions for the first group of lum deteriorated. The weather had been atrocious. On the 29th, conditions were relatively clear, with high clouds intermittently. The evening of the 30th, heavy dew, reasonably steady conditions with average seeing. There were severe gradients caused by amp glow, in future my rgb's will be dark subtracted. PixInsight's background extraction routine was used to combat gradients in both RGB and luminance sets. This image has been reduced to 80% of the original. |
