Sequence Generator 3.1 is Released!

Sequence Generator (Stable) is Released for General Use

Hello! Thanks for keeping SGPro up to date. This release on the stable branch is free of charge to owners of SGPro 3. The list below contains a brief description of all feature additions, changes and fixes in this version.

Note: This release marks end of life for SGPro 3.0 (no longer supported)

You can find it here:

Help files are (mostly) updated to reflect new features and changes in SGPro 3.1. You can access help files via the Help menu in SGPro or online here: About Sequence Generator Pro

Major Changes

  • SGPro can now load VERY large sequences VERY quickly. After the first target loads, the rest will perform calculations and rendering in the background allowing you to get moving quickly. There is no need to wait for the sequence to finish loading to use SGPro or even run the sequence. The only difference you will see is that, if you click on a target that has not yet finished loading, there will be a small pause while it gets loaded.
  • Restart on Safe: This feature should only be used if you have SGPro and PHD2 setup such that you can load a sequence, connect all gear, do NOTHING ELSE, click “Run Sequence” and have success. If you require other manual operations to start your sequence, they will not happen during restart.
    To enable Restart on Safe you will need to select the option in the Tools>>Options>>Sequence Options>>Restart Sequence when conditions are safe. You will also need a safety device connected.
    When conditions are unsafe SGPro will run the “End of Sequence” options and then immediately restart the sequence and pause. This will almost certainly end up in a paused state where SGPro is waiting on the conditions to become safe. SGPro will wait indefinitely in this state and will require 5 continuous minutes (currently not editable) of safe conditions before it will restart (unpause) imaging. Because of this your “End of Sequence” options should be such that your equipment is in a safe position (mount parked, observatory closed, etc). If you fail to park or home your gear, it will continue to track while waiting for safe conditions. When conditions become safe SGPro will perform a “Reset Sequence (Preserve Progress)”, select the target with appropriate start/end times and then run all of the normal “Run Sequence” events (cooling your camera, auto center, auto focus, starting guiding, etc).
  • SGPro Notification Center: This has been presented in a couple of other threads. See here: The intent of the SGPro notification center is to provide a user readable log of recent events, warnings and errors. Some aspects of Astrophotography are complex and when your sequence fails it it not always clear why. This should go a long way in working to reduce confusion and aid in general troubleshooting.
  • Auto focus: SGPro now uses a much more robust fitting algorithm to determine where focus lies. It is much more tolerant of bad data at the edges of auto focus runs (aka “wings”) Thanks to these very smart folks @bulrichl, @mikaelA, @jmacon).

Smaller Changes

  • Recovery will now persist through a meridian flip and continue recovery on the other side
  • The Mosaic and Framing Wizard can now download very large FoVs pretty quickly (was previously limited to ~15 degrees)
  • Option to attempt to move to the next target when the sequence fails
  • Copy target settings to other targets (handy for mosaics)
  • SGPro will now allow centering, focus and guiding startup routines to complete before waiting for TEC to be at temperature
  • Copy events to other targets is now BLAZING FAST.
  • Full support for Telescopius list and target import
  • RBI mitigation for FLI cameras
  • Full integration with SkyGuard (still beta)
  • The target display window (upper left of sequencer) is now bigger… don’t get too excited because the text has also gotten bigger so it’s easier to use. Displays ~7 targets now. We will experiment more here in the 4.0 beta.
  • The target settings icon is not visible until you move the mouse near the target list. Grants more display area to the target name.
  • Moved sequence time stats to the bottom of the sequencer window
  • Copy events to other targets is now BLAZING FAST.
  • Reorganized the sequence data and controls in the top middle of the sequencer
  • Formal integration with the ASTAP plate solver
  • Right click on an image tab to open containing folder and highlight the image file
  • Right click on Image window tabs and “Close”, “Close All But This”, or “Close All” Image(s)
  • Mosaic and Framing Wizard will optionally use color images for the working canvas
  • Most decision points that are prefaced by “Are you sure?” dialog boxes now have a “Don’t show again” checkbox (for those you who dont make click mistakes when you’re tired).
  • Telescope icon now points up… why was this pointing down?

Tons and tons of tiny things and bug fixes…
