Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Sorry, my question is certainly stupid.

I have manage to combined several filtered monochrome views into a nice HaRGB image, but when I us the "save" button, it exports a fits file.

I just wonder if it is possible to export into other image format like Jpeg or tiff ? Didn't find any option in this way

Thanks

Regards

@alpheratz06 Hi Jean-Philippe,

In my opinion there are no stupid questions. Once you have saved the HaRGB file, it appears at the bottom of the files list at the bottom of the APP window. You can double click it there to open it again. Next you can enable the Stretch check box on the upper right and then click the Save button. You will then get a popup for the file name and then a popup for the file type. There you can select JPEG or TIFF.

FYI FITS is the de facto astronomical standard for data, including images, and is in every sense of the word a "true" image file format 🙂

 

HTH, Wouter

@wvreeven Thank you very much , it worked great.

By the way , I'm a very unexperienced astro-photographer (even though I've shot a few non-astro picturesà and the results are very impressive.

I have attached my first "serious" picture, I mean with an astro camera, filters, and the result I got from scratch is very promising. orion of course, no alternative with respect to shoot toward the south (serious lockdown here) , not possible polar alignment, seeing far from perfect.

Regards

@alpheratz06 That is really great for a first result. Well done!

I see a lot of short colored lines in your image. Those are caused by hot pixels and by drift in your images. You can get rid of those by using dark frames, which help APP to identify and correct the hot pixels. Good luck!

@wvreeven I'm eager to do much better, I will learn and practice about calibration (dark etc) I noticed also vignetting is very important so I will manage to shoot some flats

Thanks , I appreciate your help.

clear skies !
