Why would one need to select mode: no registration when you only stack, I even don’t see it in the stack tab, probably a blind spot.

Ok, let me know if it happens again, and try to replicate the problem.

If you aren’t using masters from RAWs then this is correct Rob. Just load your old masterdark (from PI) as a dark and create masterdark, then APP wil properly make a masterdark of your old masterdark and it will perfrom analysis on it (check fits header by using details selectbox above image viewer). This also applies to your old masterbias and…[Read more]

I think Rob is working with mono channel data, then the Halpha debayer mode is useless @supernov.

Yes, process the channels seperately Rob. Registration can be simply done when you have the stacks ready. Just load the stacks and register them and save registered frames.

Or another way.

Hmm, okay, to use the Ha stack as your reference, you will need to do the star analysis on the Ha-stack, so registration becomes possible. Then selecht the Ha as reference and unselect the Ha stack before starting the registration proces. Let me know if this works 😉

Usually I don’t work in the workflow. I make the stacks per channel. And then…[Read more]

This was when I still used the 1.033.1 version. I’m not sure how to recreate the error.

In the meanwhile I have updated to the 1.033.3 version.

Hi Rob, can you tell me on which version of APP this happened? If it happens again with a certain image, let me have a look at the image 😉

I know of one bug that is on my list, which can cause this, a saturation stretch on 8bit data? Could that be the case?

If you can replicate this problem, that would be most helpfull.

Marc, Unlinking like in unlinked stretch is bad practise I think if you want to have good control over your star colours.

In this case your camera simply sees the night sky as green, so this is not a green cast in your data. If you correct the data for LP and calibrate the background, and you still see a green cast in the background, then you…[Read more]

I had those as fits as well, but it’s better to reprocess them using APP. Since mine came from RAW format and I didn’t save that, I had to remake them. You can just select the seperate CCD frames and make new masters. It then, I think, properly recognizes them as masters.

When I progress them separately how do I make sure they are aligned correctly (during the registration phase)?

I think, as I also struggled a little bit with H-alpha, you better process these seperately and choose the mode in tab 0. Standard it says “Airy Disk” there, but there’s options for HAlpha etc.
