Sequencer error on stop guiding

[yomamma]

Sharpcap version 4.0.9538.0 1/23/2023
ZWO ASI294MC Pro camera
EQ6R Pro mount
WIN 10 Pro


I ran a simple sequence the other night and it errored at the end when I performed my cleanup. When time expired at 4 AM I sent a message that the job completed then the first thing I did was stop guiding. The stop guiding failed and said "'Exception' : Guiding not connected " even though all indications are that guiding should have been connected as the last message on guiding was INFO "GuideStep". When I look at the minute prior to 4 AM the guiding had just completed dithering and the last guiding updates were

It looks like guiding was active but there was a warning for the camera immediately after these info entries. I have included the portion of the log that contains the last Warning on being paused because PHD2 is dithering, thru the end of the sequence since this was at the end. Thanks for your help.

I forgot to mention that I had a stack in progress when I started the sequence and also had checked Monitor Guiding in the stack Guide tab

Hi,

there is some complexity here...

Live stacking can manage the connection to PHD2 guiding and so can the sequencer. At the moment the sequencer is unaware of live stacking having connected to guiding, so you will get this type of error unless you put a 'Monitor Guiding' step early in your sequence. It won't matter if you do this and live stacking is already doing guiding/dithering, but that step is an absolute requirement for accessing guiding functions directly in the sequencer later in the sequence as it connects up the guiding application to the sequencing framework.

cheers,

Robin

I was wondering if they may be separate threads and one could not share info with the other. With that in mind I think I can rewrite my sequence and have it connect to the hardware and PHD2 keeping everything in one thread.

Thanks for the help
