- Thin Galaxies (Tri) -

Here I will present some quite thin galaxies with an axis ratio of at least 1:5. Nevertheless this value is calculated from the given angular size, so the visual impression can differ.

12.5" f/4.5, 144x, SQM-L 21.0
bei 144x einfach zu erkennen - indirekt leicht länglich Nord-Süd-elongiert - gut begrenzt und gleichmäßig hell 		EASY

NGC 973 (Gx)

../images/dss/dss2blue_023420.10_+323020.01_5_web.jpg
Image source: DSS II (blue) - 5'×5'
Name: NGC973, UGC2048
Type: Gx, Sy2
Constellation: Tri
Coordinates: 02h34m20.10s / +32°30'20.01"
Brightness / Size: 12m.8 / 3.7'×0.5'
Robert Zebahl
8" f/6, 80x, Bortle 4-, SQM-L 20.8
At 80x and 150x very thin, elongated, tapering endings, evenly bright.

 		DIFFICULT
René Merting
12.5" f/4.5, 144x, SQM-L 21.1
bei 144x mit viel Konzentration und field sweeping ist die Galaxie blickweise leicht länglich zu erkennen - bei 206x wird es ein wenig einfacher, hier ist ab und an ein 3:1 elongierter Nebelhauch erkennbar 		DIFFICULT

UGC 1281 (Gx)

../images/dss/dss2blue_014931.71_+323516.20_5_web.jpg
Image source: DSS II (blue) - 5'×5'
Name: UGC1281, PGC6699
Type: Gx
Constellation: Tri
Coordinates: 01h49m31.71s / +32°35'16.20"
Brightness / Size: 12m.6 / 4.5'×0.5'
Robert Zebahl
8" f/6, 133x, Bortle 5, NELM 5m.5+, SQM-L 20.8
Glimpsed with averted vision as very faint, very elongated nebula.

 		DIFFICULT
8" f/6, 133x, Bortle 4, NELM 6m.0+, SQM-L 21.1
Very thin, elongated, evenly bright. Faint.

 		MODERATE
René Merting
12.5" f/4.5, 206x, SQM-L 21.3
bei 206x zeigt sich die Superthin indirekt als diffuser länglicher gleichmäßig heller Schimmer - Elongation 2,5:1 		MODERATE
