saw this visually for the first time on Friday night. it's quite faint but with averted vision and the 12" managed to see it well enough despite the local light pollution and the rising moon at the time. might have a better chance tonight although the transparency is against me this time!

your image is excellent. love the scale and the solid appearance of the nebula - lovely.

this is a great shot hoping to try this myself when it clears

Some very fine detail Danilo. Could you say a bit more about the the equipment you used?

[PAC]

Good detail there, well done!

Thank you, with pleasure!

The Flat Field Camera (abbreviated: FFC) SCL, Focal = 760mm f/4 of the Lichtenknecker Optics (Belgium) is a concentric aplanatic reflecting telescope with external focus, very bright (f/4), particularly indicated for long exposure astronomical photography.

It is an uncommon telescope in which the optical image formed on the focal plain, besides proving correct is also perfectly flat inside of a circumference of full light equal to 60mm, corresponding to an apparent field of over 4°(for film 6x6cm).

The optical configuration consists, essentially of three optical elements in glass Duran 50 at low coefficient of expansion. Following the optical light path we find: aspherical corrective plate; a primary spherical mirror and a secondary convex mirror of great dimentions; halfway between the plate and the secondary there is an opaque circular diaphragm.

This picture shows the FFC in parallel with a Pentax SDUF II 400mm f / 4, when I was in the mountains:

The mount is GM2000.

You've got some great looking kit Danilo and that scope looks particularly interesting. Very interested in seeing more of your DSOs.
