Re: [Utah-astronomy] Galaxy NGC 6946 through smoke and meteors
Hi Dave, I just follow the handbox instructions. First I use a compass to get it aligned generally north. Then I level the base of the tripod. Them I turn it on and the system takes a GPS reading and tells me to put the scope in "home" position. It then does a turn and tells me to center the Pole Star without using the handbox. After that it spews to a bright star and tells me to crnter it by using the habfbox. When I do that and press enter, it's aligned -- Joe ------------------------------ On Fri, Aug 16, 2013 4:02 AM MDT Dave Gary wrote:
Nice images, Joe. What technique do you use to polar align your scope. The drift method or iterative alignment?

Wow. I wish mine were that easy. I have the same alignment routine (minus the built-in GPS as mine is a classic model). However, I have a freeware hack that I use that can transfer GPS coordinates from my handheld GPS to the scope controller. With all that, my stars never look very round. They’re more like rugby balls on the shorter exposures and get worse on longer exposures. I’ll have to work on it I guess. I have a Milburn wedge and it seems sturdy. Work….work….work. It never ends. Another stupid question. Have you ever done this procedure with the camera in place, centering Polaris and the alignment star while looking at the computer screen?

Hi Dave, I don't do it with a camera in place because the way I use the camera, with an extension tube, it would hit the wedge when it was pointed that high (toward the North Star). Instead, my finder scope is aligned well with the telescope and I peer through it.
