Trifid Nebula, this time with more data, but still too far North.

Trifid Nebula, this time with more data, but still too far North.

With the Trifid Nebula barely getting 18° above the horizon, this was a challenge. The seeing was bad over these 7 nights and most frames were unusable. The ones I could use still had stars elongated by atmospheric dispersion into rainbow footballs. With all that said, I'm actually happy with this result.
I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro. I managed to get 3 hrs 35 minutes useable exposure time, with 43 x 300s subs. I processed it in SiriL, Starnet, GIMP & G'MIC.
