Re: Unguided Imaging with a SCT

Cal Sandfort

The particular focusing software mentioned when using the InnovationsForesight's ONAG is not really required unless you want to have continuous focusing as you expose images. Otherwise, you can use your existing methods. The only difference will be that the guide stars will be more or less in and out of focus because of offsets from different filters but guiding algorithms typically handle this very well.
