Re: New to Plate Solving
- Hello Dave,
It sounds like you do not have a permanent set up for your telescope. Leaving the camera attached is a good way to go. If you can get the guide star on the chip, you can use CCDSoft to tweak the scope's location. First, write down the guide star X and Y location. On the next night, all you have to do is get the guide star on the chip and use CCDSoft's Move To function to move the guide star to the previous spot on the guide chip. However, you really don't want the guide star at EXACTLY the same location. You want to be off by a couple of pixels. This will greatly reduce noise when you register and stack the sub exposures.
I suggest looking into the AutoDither plug-in for CCDSoft.
If you cannot easily reacquire the guide star, you may need to do a plate solve and sync. Be sure to set the time on your computer every night with the Windows Internet Time Sync.
Hope this helps,

I want to use plate solving to put the camera back into the exact same spot over multiple nights (camera is left attached to scope). After plate solving, how do I get the mount to slew back to the same place as the previous nights? Do I take a new 'alignment' image the new night; plate solve and sync to 'alignment' image; then slew back to the RA/Dec coords from the previous night. I think there is an easy solution to this but I am just missing it.
