Mars captured with Python in SharpCap<\/figcaption><\/figure>\n

SharpCap allows users to add Python scripts to setup and control captures and perform other functions.\u00a0 I recently wrote a Python script to capture Jupiter, Saturn, and Mars.\u00a0 Specifically for Mars, it prompts the user to manually select an IR filter, captures nine sequences of 120 seconds each, prompts the user to manually select a L filter, and captures another three sequences of 120 second.\u00a0 This script will be discussed in am upcoming video of my methods for capturing Jupiter, Saturn, and Mars using the ZWO ASI462MC.\u00a0 Here is the script:<\/p>\n

To use this, Open SharpCap, select Show Console from the Scripting menu.\u00a0 Now copy the Python script above, and paste it into the editing window.\u00a0 Save it as JSM_462.py.\u00a0 Now you can run it by selecting Run Script from the Scripting menu, and opening the JSM_462.py file.\u00a0 With minor modifications, this script is used to capture Jupiter, Saturn, and Mars.\u00a0 As I said, this will be further discussed in an upcoming video.\u00a0 Stay tuned for more!<\/p>\n","protected":false},"excerpt":{"rendered":"
