B 10x50, [OIII], SQM-L 21.5
NGC 6960 zeigt sich nur bei der Kombination UHC+[OIII] und dann auch nur der Nebelteil südlich des hellen Sterns 52 Cyg - er wirkt sehr schwach und breit verwischt

MODERATE
100mm f/6.4, 20x + [OIII], SQM-L 21.5
bei 20x und mit UHC zeigt sich der nördliche Teil scharf begrenzt und spitz, während der südliche Nebelteil breit und diffus ausläuft - mit [OIII] sind weiter südlich jenseits des Besens einige Kondensationen mehr erkennbar - ohne Filter zeigt sich nur die nördliche Spitze, wenn ich den hellen Stern aus dem GF nehme

EASY
8" f/4, 25x + [OIII], SQM-L 21.5
bei 25x und [OIII] zeigt sich der Nebelbogen im Norden besonders hell, im Süden fächert er breit und diffus auf - noch weiter südlich sind weitere Aufhellungen erkennbar

EASY
12.5" f/4.5, 45x + [OIII], SQM-L 21.5
bei 45x sowie UHC ist NGC 6960 scharf gezeichnet mit breiter auslaufenden filamentartigen Nebelteilen nach Süden - Pickerings Triangle ist zwar schwächer, aber trotzdem sehr hell und mit weicheren Strukturen - bei 45x und [OIII] stockt einem der Atem - harte Kontraste in den Nebeln - das hat nichts mehr mit Sehen oder Nichtsehen (wie zu meiner Anfangszeit) zu tun, sondern mit: "kann man nicht mehr übersehen" - selbst die schwächeren Nebelteile heben sich kontrastreich ab

NGC 6992/5 & IC 1340 (BN)

Brightness / Size: 7m0 / -
Brightest part of the veil nebula. Consists of NGC6992, NGC6995 und IC1340. IC1340 is the fainter, southern part. Awesome view with [OIII] filter.

Pickering's Triangular Wisp (BN)

../dss/dss2red_204830.00_+313800.00_80_web.jpg
Image source: DSS II (red) - 80×80'
Name: Pickering's Triangular Wisp
Group: Veil nebula
Type: BN, EN
Constellation: Cyg
Coordinates: 20h48m30.00s / +31°38'00.00"
Brightness / Size: - / -
Pickering's Triangular Wisp is the third-brightest part of the well known Veil Nebula. While the two brighter parts (Eastern & Western Veil) are bright and well defined in their shape, this nebula is much more fainter and diffuse.

Just a faint, irregular haze. Anything but evident.

MODERATE
8" f/6, 37x, Bortle 3, NELM 6m4
Without any filter the nebula is visible only under very clear, dark skies. Hardly perceptible with averted vision.

DIFFICULT
8" f/6, 37x + [OIII], Bortle 6+, NELM 5m3, SQM-L 19.7
Quite evident with averted vision as irregular brightenings in a field of about 2°.

MODERATE
8" f/6, 37x + [OIII], Bortle 4
Only under good conditions easily visible with direct vision, otherwise averted vision is necessary. Overall fairly faint, very diffuse, without any obvious differences in brightness. Spread over a large area like wisps of fog. Moving the telescope can help to extract the nebula from the star-rich surrounding.

At 22x almost separated. The double star appeared strikingly orange and forms a conspicuous, nearly isosceles triangle with neighbouring stars. At 44x clearly separated, relatively close together with a small difference in brightness.
