Solar tracking & acquisition

Question

Hi Group,

Autoguiding on a star is no problem, but autoguiding on our local star seems to be illusive.

I would like to be able to either add track points around the sun or be able to open a circle around the entire sun.

Sometimes a close up of a prominence and stack 300 frames every 10 minutes for 6 hours and create prom. movies.

Any way this software could be used track the sun, or moon?

 

Unk

BackyardEOS and BackyardNikon are camera capture programs that are built with lots of features that are particularly useful for astrophotography.  It supports a 3rd party interface where another application can request BYE/BYN to take a snapshot, save it to disk, and pass the file path for the image back to the requesting app.  None of this is particularly useful for autoguiding, either solar or stellar.

 

Sorry!

Well I don't know what mount/driver you have but in EQMOD there are tracking rates for stars, moon, and sun. I use the solar tracking rate when looking at sunspots.

 

FYI there's an article about observing the planets during daylight in the Oct. Sky & telescope. I only skimmed it but you might check that out. I know they talked about using the "center" of the sun instead of polar alignment, or maybe it was instead of an alignment star. I Guess the latter makes more sense.

Just make sure that your Mount is set to TRACKING RATE=SOLAR, and that you perform an appropriate Alignment (Celestron offers a specific "Solar System Alignment" which can be performed using the Sun - or Moon if it is also Up).  If your Mount is setup anywhere near Level and North and your Altitude is set to the appropriate Latitude Angle, then you should be quite good for Tracking on the Sun.

Otherwise, its unclear how BYE/BYN could help, as any AutoGuiding would be done elsewhere - if you could find an App that would Guide using Sol as a GuideStar...

Using a Celestron CGEM and Advanced VX mounts in solar mode.

Need a way to autoguide to keep it centered for 6 hours for time lapse movies with my Coronado 90mm DS.

Autoguide software is designed for distant stars, nice little dots not a large local star.

Would also like to guide on the moon for an eclipse movie.
