I love planetary observing with a Starmaster. They are really sharp on planets. The combination of large aperutre and superb optics are just what the Dr. ordered for planets.

This image shows off the scope's capabilities and your skill. I might suggest that you lower the black point a bit to see if you can bring out the Crepe ring.

Saturn Improvement

Major improvement! Good work. Looks like you've got the hang of this stuff.

old orange tube c14 fork-mount tracking error?

Posted By Ron Wodaski
The ST-237 is presumably being recommended for use in a Fastar configuration. If I'm not mistaken that scope is too old to be Fastar compatible.

Your best bet is to measure the periodic error of that mount. Any way to borrow a camera from someone to do some testing?

You want REALLY large pixels for use on a C14. The ST-9E and ST1001E cameras are well suited for use on the C14. If you must use smaller pixels, then get the Optec Widefied F/5 reducer. It has a large flat field (though you'll want to do a careful collimation for best results) and brings the focal length down to about 2000mm. That's still too long for an ST-7 type of camera, however, IMO.

Using MPEG from Digital Camera

Posted By Ron Wodaski
MPEG is a "predictive" format - each frame is incomplete, only the changes between frames are stored. This makes it harder to get clean single-frame images.

But I would think that you might run into problems before that - most of the digital camera with movie capability use a lower resolution for the move images, and higher compression is also typical. Both of these get in the way of getting high-quality planetary images.

BIG Saturn.

Posted By Ron Wodaski
Wow! Gorgeous. One of th ebest I've seen this apparition. Looks like you had some large-scale seeing undulations, however. The left edge of the planet is soft, as are the rings. If you can weed out the offenders, you might do even better.

Jupiter on Dec 27th..

Posted By Ron Wodaski
Nicely detailed imaged. Good color, too, especially the subtlety of color differences.
