Before I jump into NB Ha, OIII and SII imaging I want to try processing images.  Is anybody willing to share their data?  I will not post the image.  I just want to practice with PixInsight.

 

Send me a CN email if you are willing to share your data.  Thanks

I did the same!
 

I was following Nebula Photos YT channel as he has several good tutorials on it using varying softwares. He links his stacked data to practice with.

 

I’ve also got some by request from r/askastrophotography on Reddit.

 

Finally, if you really want to have fun, I believe the Hubble and even the JWST data are available for download.

 

Btw, it’s an excellent idea to practice first.

 

i actually bought Pixinsight 6 months before I bought any equipment.

The Liverpool Telescope archive contains more data than you could wish for, though the UI is pretty obtuse! Hobby Astronomer has posted on this in CN in recent years.

Ok.  Here's my very first processed NB image using FIT's SII, Ha and OIII data from 'leemr' "M16 Narrowband Processing Challenge" posted on Cloudy Nights August 2016.  Leemr’s imaging setup was a Sky-Watcher Esprit 120mm f/7 and imaging camera an ASI1600MM-C.  I thank ‘leemr’ for using the FIT’s images.  This image will be deleted later.

M16 narrowband image processed with PixInsight 1.8.9-1.  The black point is darker than I would like.  This may be caused by Flickr JPEG compression and my fault using the Histogram Transformation.

I have tonnes of data sets on many targets. I would be fine sharing any but they are HUGE.

Nebula Photos presents a fun tutorial on how to download and process JWST data in Pixinsight.
