Messier 20 (trifid nebula), Sagittarius
• mount : Takahashi NJP driven with Astro-electronic FS2
• guiding : off-axis guide with PHD2.
• Telescope / Lens : Takahashi TOA-130S (F = 1000 mm, f = 7.7)
• camera : EOS 60Da
• camera parameters : ISO 1600, and 360 sec x 5 frames (stacked and trimmed).
• processing : Adobe Lightroom CC and Photoshop CC
At a not-so-busy night, I went to dark mountains and tune my larger equatorial mount (Tak's NJP) with a telescope 1m focal length.
Guiding parameters for diurnal motion is not completed yet and star image is not true circular in this photo. The problem, however, gets gradually to converge, I think :-)
