ST-4 Imaging

Hi all,

Anybody ever actually try to use the St-4 as an imager?

I have been guiding with it, and decided-what the heck--to try and image Jupiter. I was using CCD soft, and focusing on Jupiter--(eyepiece Projection 3.8 mm and 10 mm Plossls, TV 85). And--to make a long (cold) story short--could never really get focus or an image.

Is there a collection of helpful hints somewhere on the web?

Hi Alex,

I remember once many years ago reading someone's web page about imaging with an ST-4. Unfortunately I cannot remember whose. :-(

I did however spend some time imaging with an ST-4 with good success. For planetary imaging, I found it easiest to focus on a nearby star or for Jupiter, one of the moons. After focusing, then go to the planet. Were you using the ST-4 in planetary mode? You need to because to image planets the ST-4 has to use only half of the chip, so that it has somewhere to store the image during download.

You can see a couple of my images at: http://www.acad.carleton.edu/curricular/PHYS/Faculty/MClark/jupiter.htm

The images from May 5 and Dec 22 were with the ST-4.

Cheers,

Maurice
