DSSR v3 Released!

Filed under: Software — Dave @ 12:21 pm

We have just released a major upgrade to Dave’s Solar System Recorder (DSSR) which is now at version 3.0.

DSSR is detailed on its home page at right. The download link and the user manual are in the Support and Downloads page at right.


Same version works on both 32 and 64 bit Windows.

Three separate autoguide methods.

Autoguide using GEM and Celestron and Skywatcher alt-az mounts.

SmartTrak keeps on target during cloud cover.

Support for parallel processing for faster guide target recognition.

Monitor target drift without applying corrections.

Calibration of scope/camera combination.

Manual control of mount motor rates for precision manual guiding.

Graph window to show guide error and mount tracking error history.

Screen desktop recorder.

Separate stop buttons for mosaic and sequence captures.

Mosaic tile rotate options.

Turn tracking on or off in scope window.

Zoom video window with mouse wheel.

Pulse guide support for EQMOD and Paramount MX mounts.

And lots of bug fixes and other improvements.

Below is a solar prominence animation taken on a Celestron NexStar 4SE mount in alt-az mode which was autoguided by DSSR’s new AzTrak module. The guide target was the large prominence which the Sun appears to rotate around. This rotation is normal for alt-az mounts.
