Here's my first image of Jupiter in a couple of weeks, all thanks to a
break in the clouds and fog that have settled around here lately. The
seeing was only "poor to average" for this image, but there were enough
good frames to produce a decent result. Not as nice as Pauls image from this morning :-)
This is also the first Jupiter image with a new scope, using a 14.5"
Royce conical. There's no cooling on the new scope as yet so it's at the
mercy of the ambient temperature.
Ganymede can be seen in transit, nearing the end of its passage across
the disk. A prominent red oval is also visible in the northern
hemisphere (bottom).
Still a pretty good iamge Anthony, I wonder if you were observing the mirror flexing without the cooling. What was your blue channel like? Mine was horrendous.
I quit just after Ganymede made the meridian. I had been up all night and was stuffed by then, still pretty tired now. Not much paper work getting done today unfortunately.
Wow – what a feast; the 2nd Jupiter for the day and what a ripper it is! The small red oval towards the bottom of the disc is very clear and distinct, as is the surface detail on Ganymede. It seems that one needs to resolve detail on Ganymede these days, just to get the privilege to post an image!
Lovely work as usual, despite your rig being a work-in-progress.
You must be very pleased with how your Nemesis project is progressing.
No doubt the absence of your Peltier cooler would have played a part in the resolution of this image.
It is still a very good image with a great deal of detail and structure, possibly just not as smooth as it would have been with the cooler.
Thanks all, the system is coming together better each day with more tinker time spent on sorting out issues with some of the new gear.
Paul, the red channel was definitely the best, but green and blue weren't too bad. Speeds were 40fps (red and blue) and 47fps for green. I was close to a full histogram in each channel, in fact I was concerned that the green channel might be burned out but I was just ok. Jupiter was 380 pix across the diameter in the camera, doesn't leave much room on a 640x480 camera.
