20251212 A short but hopefully longer observation session

The forecast is no good, but the worst case is not raining.  

So I pulled out my bigger rig to test out my new Antlia Quad Band filter.  Also, I am testing my new wiring, basically connect the EAF and guider cam to the main cam.  It works out well.

However, my new power cable was not working.  I ended up using my old wire first.  I have to turn off cooling to make it works.

The main camera was pointing at the Soul Nebula IC1848, taking 5 minutes exposures.


And then I switch to the Lobster Claw Nebula SH2-157 in order to avoid meridian flip since I will have a meeting soon.


After the meeting, I turned the main setup to M1 in the hope to capture some more detail.


After setting up the big rig, I pulled out also my S30.  The Ghost of the Cassiopeia IC63 will be the target of the night.  Over two hours of exposures are accumulated.


Then I switch to M42 for some more mosaic:


Cloud did roll in to ruin some of the shots, but it's still a night worth setting the stuff up.

The bigger ipad is monitoring the S30 while the smaller ipad is monitoring the ASIAir running the bigger rig:
