Thanks to some recent time on ASEM's C14 scope, I've pulled down a full color image of our giant neighbor with my best resolution yet!
In this image, I acquired separate L, R, G, and B images through a 2x barlow at an effective focal length of 7820mm. Â The terrible atmospheric seeing in my area is clearly evident at this level, but with luminance subexposures of 22ms, the video was able to "freeze" and cut through some of this. Â The longer exposures required for the color filtering at f/22 didn't fare quite as well, but with the detail coming from the luminance data, we're left with a pleasing view of the intricate sweeps of the Jovian clouds.
A bit of miscollimation was mildly evident through this acquisition, and while the wavelet application in Registax 6 was able to recover a significant amount of detail, I believe a little tweaking will take the imaging capability of this scope to another level. Â When we get more clear sky opportunity, I'll get a little more familiar at ASEM's observatory, and will attempt my next lunar and planetary challenges. Â But with this image, we see what this scope is capable of, and are able to take in the artistic churning of the gas giant's clouds.
