Jupiter and Io - digicamPosted By Lee Zagar |
Jose,
Great image, considering it is only a stack of 40 or so images. I also tried the same thing with my LX-90 and Sony F717 with a Scopetronix Maxview II eyepiece. I was able to stack about 100 images, but my results don't look as good as yours. How did you process your image?

Ido,
I took a shot at reprocessing your image. I used unsharp mask and adjusted the color intensity in Photoshop.

Digital pictures of JupiterPosted By Lee Zagar |
Douglas,
To get decent photos of the planets, you need to stack many images, at least 50 or preferably 100 or more, with a program like Registax, a free program (http://aberrator.astronomy.net/registax/). Set your camera to manual focus at infinity with the lens wide open. The shutter speed should be the fastest you can use and still get a recognizable image. Start with about 1/30 second and go up or down from there. Underexposere is better than overexposure. Registax adds the images, so overexposure will result in completely washed out details.
With lots of practice you should be able to get decent photos. Here is a composit of a single Jupiter image, 25 images stacked and 100 images stacked.
Keep trying and good luck.

Jim,
Nice image. I hope you don't mind, but here is what a little processing can do.

What is thisPosted By Lee Zagar |
Dan,
It looks like vignetting. Here is your image processed in Photoshop to even the background.

C80ED HardwarePosted By Lee Zagar |
Oren,
I have not heard of anyone upgrading their focuser on the 80ED, but both Feathertouch and Moonlight make really nice units. If you do decide to upgrade, I would be interested in buying your old 80ED focuser.

help processing saturnPosted By Lee Zagar |
Mauricio,
Your image is essentially out of focus; however, with some processing (unsharp mask and adustment of levels) I was able to improve your image somewhat. Improving your focus will produce much better results.

Stiletto focuser vs DSLR softwarePosted By Lee Zagar |
Ivan,
I am using a Stiletto focuser with my Canon 300D (Digital Rebel) and it achieves perfect focus every time in just a few seconds. It works exactly as it is described on the STI website. The other advantage is that it does not require a computer. I have tried every other method and, in my opinion,the Stiletto is the easiest and quickest way to get perfect focus.
Here is a sample of my first image (M13) using the Canon 300D and the Stiletto.
