Moon phase retrograde

Watchface Design Expression Help
1

I use a mask with two 80% opacity circles to move over the moon twice in one 360 degrees rotation. So there is a 180 degrees rotation per moon. However, because of a new design, I want the mask to only make a 180 degrees rotation and then jump back to starting position. A moon phase retrograde. Udsing just one masking circle of course. This is the expression I currently use:

((((round(((((((367*#Dy#)-((7*(#Dy#+((#DM#+9)/12)))/4)+((275*#DM#)/9)+#Dd#+1721013.5+(#DH#/24)-(0.5*(((100*#Dy#)+#DM#-190002.5))/abs(((100*#Dy#)+#DM#-190002.5)))+0.5)-2458135.6)/29.53)-floor(((((367*#Dy#)-((7*(#Dy#+((#DM#+9)/12)))/4)+((275*#DM#)/9)+#Dd#+1721013.5+(#DH#/24)-(0.5*(((100*#Dy#)+#DM#-190002.5))/abs(((100*#Dy#)+#DM#-190002.5)))+0.5)-2458135.6)/29.53)))*29.53)*1000)/10)/100)*6.095374739)+90)

What do I need to change to turn it in a moon phase retrograde expression?

for reference try see this

“Inspect Mode” Available :slight_smile:

Hi Ben, tnx for responding. I don’t see an inspector mode, so I cannot derive the code…

try this link https://www.facer.io/watchface/6ciWO7uB5L/inspect and select element moon.png see expression at Rotation… hope this help :slight_smile:

Thanks Ben! But just like I usually do, you use two moons who share a 360 degrees rotation, 180 degrees per moon cycle.I want to use just one moon what jumps back to starting position after a moon cycle. So just 180 degrees rotation and then jump back. Do you know how?

I have the answer. It’s so simple: just divide the whole expression with 2. I will publish my watch face Universe-3 today after some tweaking.

Published. Can you check if it is working correctly?
