This is a single session of 60x60s frames, using my Canon T5 camera on my SkyWatcher BlackDiamond 150/750 telescope, and stacked using Deep Sky Stacker with darks, dark flats, flats and bias frames. No dithering. Post-processing was done using Pixinsight. This picture was taken in Santa Pola, Alicante, Spain, on June 20th, 2017.
Even if walking noise was a problem during post-processing, I was quite happy with the coloration and the details of the dark clouds, and also M21 can be seen..
This are 4 sessions for a total of 300x60s frames, using my Canon T5 camera on my SkyWatcher BlackDiamond 150/750 telescope, and stacked using Pixinsight with darks, dark flats, flats and bias frames. Manual dithering was done every 5 frames. Post-processing was also done using Pixinsight. This picture was taken in Santa Pola, Alicante, Spain, between June 20th and June 26th, 2020.
Improvement is noticeable, specially because post-processing was easier since the walking noise was eliminated when dithering. M21 is also noticeable in the top right corner.
