| Celestron C14, 2x Powermate. ASI 120MM Focal Length (Measured) about 8600mm Image Scale at capture 0.09"/px (~ 30 miles/px) Alt 43°, Apparent diameter 13.18" Astronomik R-G-B-NIR filters. Starlight Xpress Fitler Wheel FireCapture for Capture (Highly Recommended) Two sets of data, each 3000 frames/filter captured as 16 bit SER. Best 350 of each selected The images from each set were then combined using WinJuPos. The "Red" channel is actually a composite of 4 images, the two Red images and the two NIR images. Martin Lewis has shown that there is a diffraction ring artifact whose position relative to the limb of the planet is a function of the wavelength captured (and of the diameter of the OTA). By combining the R and NIR images this ring artifact was averaged out. |
