Tracking Needed?
Posted by 67champ on Tuesday, December 17, 2013 9:00 AM

If I am going to shoot video with a planetary astro camera from my 127mm mak-cass prime focus setup; and then post process to get best possible single stacked image of the lunar surface, does my mount need to be able to track the Moon?  Can I get great results if I dont have tracking?  Thanks!

Helpful, yes, but whether it's required depends on the image scale / focal length and polar alignment of your system.

You can get good results simply by letting the Moon drift through the field of view while recording an AVI, which you later process with software (e.g., Registax) into a single frame.

To get Great results, you need to match your image scale, exposure settings, focus, and processing to the seeing at the time of capture. If there is image movement, the result might be very good, but not optimum.

If you already have everything you need EXCEPT a tracking mount, go ahead and try it with the drift method and see what you get. Practice makes perfect!

Thanks.  I have the motor drive that came with the mount (CG-5) I could try to install it...  I dont know what rates it moves at..

The CG-5 has lunar, sidereal, and solar tracking rates.
