I was busy yesterday. I rebuilt the optical tube on my 127mm because that home made focuser just wasnt aligned and I could not improve on it. The optical tube was also too short, which I made up the difference using a piece of 2 inch pvc. I had another piece of 5 inch tube that was a little bigger than the correct size, so I cut the tube, and it is now the perfect length. I have also aquired those 2 114mm reflectors. I removed one of the focusers from the worse of the 2 scopes and epoxied it to a new end plate made from a piece of raw electronic printed circuit board material.
Everything is nicely aligned now. I started photographing Jupiter around 0400 local (0800Z). I finished the session taking a sequence of 7-1000 frame AVI's to be used to make this animation:
As you can see, the detail that you can see on the planet is real and not noise due to sharpening. I actually was a little conservative on the amount of sharpening that I did on the image. The GRS is visible, as well as a barge in the NEB. Note that the NNTeB and the NTeB are both resolved and rotate. Detail in the EZ is resolved. Going to the south, I am resolving a north and south component in the SEB with white spots seperating the 2. The STeB & SSTeB are there, but poorly resolved, however you can see rotation there.
This is my first attempt at an animation. I havent quite figured out how to make an avi animation, but this animated gif worked out.
The following images are images I had taken earlier in the evening, testing the changes made to the scope. I could see right away from the images on the screen that I had made progress. My most detailed still image I believe is to the left. I have never been able to get this much detail before. Also, the red spot is more yellowish in this image, which approximates the color I have seen in other recent photos.
I took quite a few AVI's this evening, and if I posted everything, this would be a rather long post. I will, therefore, put up only the best images I took this morning.
This last image is a tossup between the "best" image at the top of this post. This image shows more detail in the white areas than the other, but the other shows a bit more contrast. The 2 images were taken about 5 minutes apart. The difference between the 2 are mostly post processing differences.
This morning's conditions seemed quite good, transparency was excellent because of the lower humidity, and seeing wasnt half bad, better than average.
I am still having trouble finding the optimum focus. It is difficult to tell on the screen . Basically, I have been shooting for sharpness on the fully lit side of the disk, as well as best contrast in the belts.
Also, I was able to see (but not photograph) Mars. I believe it is still quite small. The next morning I do this, perhaps I'll take an AVI or 2 of Mars, just to see if I can see anything with it so far away. I doubt i will be able to, which is why I didnt attempt it this morning.
