Another Batch PreProcessing?

[sreilly]

I use ACP/MaxIm for image acquisition and process almost solely in PI. My setup includes use of a Pyxis 3" rotator and dual chip SBIG camera. When imaging my setup takes an image, plate solves, and then corrects for any problem in image rotation and position. So in the course of the night I have images taken on the East side of the Meridian and then after the Meridian flip, on the West side. So because of this I need to take flats for each side of pier and create my masters. Is there a way for the BBP script to read side of pier and apply the master flat frames accordingly? Otherwise it seems to me I can still use the BPP but only for the two groups of images separately and then only by using as calibrate only. The resulting images I can then save and use the Image Integration Tool and combine them.

Is there another way using the BPP script that I'm missing? So far I don't think any processing software has the feature to read side of pier and apply the proper flats. This would certainly eliminate the need to research each night the time the mount does the Meridian flip and process accordingly.

i think this came up recently and juan said that you can use the "Add Custom" feature to support this, but it's not automatic. i've never tried it but i'm guessing you have to add your 'rotated' lights with a fake filter name and then add the flats with the same fake filter name.

Thanks Rob.

I'm guessing that you mean fake filter name that instead of say Blue I might have BlueW for the West side of pier? So I'd have to change the name in the master flat FITS Header to reflect this as well as in my images taken on the west side?

right, a custom filter name to indicate the side of pier. but you don't have to change the fits header; i think you can add your lights with "add custom" and define the fake filter name there, then add the flats the same way with the same filter name. i guess you only need to do one custom filter name since "Blue" can just stand for east in your example above.
