Techinical Problems with Astrophotography
I posted the first of several piggyback shots I took a week ago Friday. I had some problems with light pollution from car headlights and some wind. But the biggest problem was that my piggy-back adapter is not high enough above the telescope. I got some of the telescope in the lower left corner of the slide. I don't know if I should put the piggy-back bracket in another area on the clamshell ring or if I need to have another bracket machined so it is an inch or two taller. I pointed the camera towards M11 in Scutum and got some of the Milky Way in that area. It is image #18 in Debbie's folder. Hopefully I can get out this weekend and find a solution to my problem without getting a new bracket. The E200 film picked up lots of nebulosity in my slides. I was viewing my slides last night while trying to watch the baseball games. Is anybody getting any sleep lately with these ball games going into extra innings? Debbie
Debbie, don't shoot directly over the front of the tube assembly. You should have plenty of room if you aim the telescope some distance (up to 90 degrees) away from the area you are imaging. Alternately, you might try a ball-type tripod adapter that will allow much more freedom of movement.

Debbie, Kim is right, except don't guide 90-degrees off your target. A few degrees is enough. I use a Bogen pan/tilt adapter myself, attaches directly to your piggyback bracket. Orion used to carry them but you can get them locally. Too, a slightly longer lens may crop-out the tube. --- astrodeb@charter.net wrote:

You bet, the game always puts me to sleep anyway, extra innings are just insurance. ;) __________________________________ Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish. http://promotions.yahoo.com/new_mail

Had the same problem with my C-8 and later my C-14. In both cases I fixed the problem by moving the piggyback adapter and camera to up near the front of the tube. Patrick
With that solution, I suspect some telescopes may need balance weights. At the back of the tube it's close to the axis and doesn't tend to throw off the 'scope too much. But at the front it may be off balance. Just a thought. -- Joe
