Multi-session question

Hi Mabula,

Last night, 2019-03-24, I completed a second night of M101 in Ha. The first night was on 2019-02-17. In total I have 3.1 hours total integration time. Today I tried creating a stack that combines both nights. I do know about APP's multi-session and have used it with success in the past but I've used it only in the context of matching Lights and Darks by temperature in a single night. Now I have two nights, and I am running into problems. You may have guessed that I don't have a cooled camera.

I've attached a screenshot. Explanation follows:

Each night I capture a new set of Bias and Flats. Those I load and assign a session name of '20190217' and '20190324'. The Darks span the temperature range of 19.5F to 22.5F on the first night and 27.5F to 31.5F on the second night.  Since the temperature range is large I divide the Dark frames into four sessions: '20190217_19F5_20F0_20F5', '20190217_21F0_21F5_22F0_22F5', '20190324_27F5_28F5_29F0_29F5', and '20190324_30F0_30F5_31F0_31F5'. The last step is to load the Lights. I know their temperature so I assign them to the proper session.

The problem is this: the Lights know about the Darks but don't know which Flats and Bias to use. The reason, as best I can figure, is that I can not assign more than one session to the Lights. I would like to put a check mark on both '20190217' and '20190217_19F5_20F0_20F5' but the check mark controls are behaving like radio buttons.

Is there another way of accomplishing this besides purchasing a cooled camera?

Thanks,

Brian
