Webcam Noobie Question

Hi, all

I've been observing for some 14 years now, and have always been a dob man. My latest is a 16" f/4.5, coupled with a Denk. I've always been visual, but I'm curious about taking planetary photos. No drive, no eq platform...just push.

I fiddled with my digital camera at the eyepiece, and it got me curious about taking and stacking planetary photos with say, Registax.

Can it be done without a drive? In other words, can I take a series of photos, move the scope, take more, and then stack them? I guess it all depends on whether or not the software can stack photos of say, Saturn, when it isn't in the same part of the field (since with no drive I will have drift....).

As I said...visual man asking a very basic photographic question. All advice is very welcome.

Clear Skies,

guy

Guy, yes you can... Registax will take care of that, as long as the planet is still within the frame.

Of course, you must realize that "the higher the magnification, the faster the object will move in the FOV", so you will have to play catch-up quite a bit... wink (that's why a tracking mount is HIGHLY desiderable)



Clear skies, and good luck!
