Like a lot of people I used the
So here's my layout:
I tend to get aligned, focused, plate solved and on target prior to starting the sequence. So my Start Up section sends a notification to my phone, and cools the camera (in case I forgot!) And loads the Luminance filter. These tasks are done in parallel.
The target is imported from the Framing tab. Then I centre the target, run autofocus and start guiding. There are eight triggers monitoring the session, most are self explanatory, but I've just added Centre After Drift, When Becomes Unsafe and Interrupt When RMS is Above. Centre After Drift does a plate solve after every exposure and recentres if the target has drifted. The good thing about sequences is that they can be modified whilst the sequence is running. I adjusted my settings to every exposure and if more than 1 arc minute. When becomes Unsafe uses my Arduino rain sensor as a Safety Monitor and sends a Notification to my phone if rain is detected. The Interrupt When RMS is Above is a PHD2 Tools Plugin instruction that halts the exposure if the guide star is lost due to passing clouds or whatever.
Then I loop exposures till Astro Dawn or sometimes, if the target drops below 30°, depending on the target. Whilst capturing I use the Pegasus PPB as a Weather source with an if statement to send a notification to my phone if the temperature drops below 2°C or the humidity rises above 92%.
The End section carries out the shut down tasks in parallel. I added the Set Switch Value to turn on the flat frame light box which I use in the telescope park position but mostly I just go to bed at this stage and do the flats the next day!
I hope this is useful and I look forward to getting ideas from other's sequences too.
