A refinement already. Good weather is a great incentive. So the LPS-P1 filter was used last night and this morning along with a longer lens and more data. There is definitely a dramatic improvement with greater signal to noise ratio due to all the changes. Next I'll try to use Pixinsight to see what else is in this data.
