First Test of DSSR’s CloudBuster Autoguider

Filed under: Animations, Software, Sun — Dave @ 3:20 pm

DSSR is designed so that you can set up your scope in the morning and let DSSR control and guide it while you do more enjoyable stuff. A key part of this ability is the CloudBuster autoguider.

CloudBuster will keep your scope on target even on days when the Sun is sometimes obscured by clouds. This lets you record automated mosaics, time-lapse movies or multiple active regions, regardless of weather.

Today, I set up my scope in the morning and started recording a prominence. I went back 5 hours and 40 minutes later when the Sun had gone behind my roof. I was well pleased to see the same prominence on screen, even though it had changed markedly and there had been lots of cloud blackouts of the Sun.

Here is the stacked 1st and 2,000th videos. (DSSR recorded around 2,000x 10 second videos at 30fps.)


And here is the last stacked image.


Here is the preview time-lapse animation that DSSR automatically generated that shows the guiding and cloud cover over the 5.5 hour period (250x real time).

CloudBuster is still being developed but this test gives an idea of what it will be capable of. My mount is deliberately badly aligned to test CloudBuster. Left on its own, the prominence would have drifted off screen in a few minutes.

I am currently running the 2000 video clips through AviStack and DVS and will update this post with the polished time-lapse animation.



  1. that is a great result for over 5 hours of tracking
