Hi Mabula,

I would like to request a Crop function, maybe in R2?

Best,

There are actually 2 crop functions,

1) batch modify tool

2) and you can integrate to a crop of the reference in 6) integrate

If you want to crop just 1 frame, use the batch modify tool ?

Wow! Thanks for the guidance :-) . The batch modify button is probably the one button I didn’t click :-) .

With the batch modify tool, you can do several modifications

1) you can mutliply your data with a factor

2) you can add or subtract an offset

3) you can adjust the (FITS) header for ISO/GAIN/ exposure time, instrument

4) you can undebayer ! so from debayered data, you can create the monochrome CFA data again ! Try it

5) You can crop using offsets, even negative offsets, this will uncrop your data, so you can add a border around your data.

6) or crop, you can draw a crop in the image on your screen and select crop OK

And I discovered a little bug.

I rotated my image on the y-axis. Next I tried to place some area select boxes (remove light pollution), when I try to place a box the box appears a quarter right under the mouse pointer.

Hmm, can you make a screenshot, your description has me guessing how that actually looks.. I am afraid.
