Last night was a rare clear night, unfortunately with full moon. I managed to get some data on NGC7000, it was not much, so, I wanted to add and stack previous data, I never tried stacking data on APP taken with different focal lengths, the new RASA11 has 620, the old Hyperstar has 540, but to my surprise, APP was able to resize and rotate the images and stack them as per the images attached.
APP did great job here and I did not loose my old data and now I can add to it and restack.
Here I have a question; IS APP able to stack different focal lengths and resolutions??
In removing light pollution, what is the best approach in selecting rectangle areas? Different locations give different results!
I have not used star removal tool in APP, how does it work? I used it before when it first appeared but was not successful.
I am glad that APP was able to stack two different focal lengths data, I know many of you knew about it, for me it was the first time.
Thank you,
Jay

Yes, depending on the image you choose as your reference frame, it can combine those.

When combining, make sure to use LNC and MBB, it may reduce the edges a bit already. But yes, that is a bit of a challenge, it's trial and error usually when doing LPC on that.

Star removal is something that depends a bit on the data at the moment, sometimes it works brilliantly, sometimes not. I tend to go for star reduction. Here's some parameters that could work, also there it's a bit of playing around: https://www.astropixelprocessor.com/community/postid/17761/

It's not obvious it could indeed, but it's why the calibration and registration engine in APP is so powerful, it also allows for (almost) 1-click mosaic creation and true distortion correction etc.
