A new photo, Monkey Head Nebula, Lower's nebula, Jelly Fish nebula and Messier 35
I shot material for this mosaic image at end of the spring season 2021. I haven't got time to finalize it until now. I kind of like this image, it's very deep and shows the very dim background mist and a very dense starfield of the galaxy plane. Total exposure time with Tokina AT-x 300mm f2,8 camera lens, Apogee u16 Astro camera and Astrodon narrowband filters is around 6 hours, the exposure time with Celestron Edge telescope is around 30 hours.
An other interesting feature in this imaging project is that I did use my VARES-processing method to this.
(Variable Resolution imaging) I have shot the nebulae in this wide field image with a long focal length instrument, the Celestron Edge 11" few years ago. I use this high res material to boost details in the wide field image. But that's not all!
I used the VARES technique to add deepness to my older long focal length images. I added the very dim background nebula data from wide filled images to long focal length images. The result was very good. Now all detailed features in the image, like stars, brighter nebula details and dark nebulae are form high res image data. The dim and relatively featureless data is taken from the wide field image. At the end the both datasets are combined by VARES-processing method to a one very deep and detailed image.

I think, this was a first image in the World showing the extremely dim lower part, "Teil of the Monkey", of the nebula.
